Gold Karat
Gold's softness and malleability make it a wonderful metal to work with when creating virtually any design in jewelry. But this softness can be a drawback as well. To make it stronger and more durable, gold is usually alloyed, or mixed, with other metals such as copper or silver. The higher a metal's percentage of gold content, the softer and more yellow the jewelry piece. The karat weight system used to measure gold in a piece is the same for all hues, including white and yellow gold.

The word “carat” is Arabic, meaning “bean seed.” This is because historically seeds were used to measure weights of gold and precious stones. In the United States, “karat” with a “k” is used to measure gold's purity, while “carat” with a “c” is used in measuring a gemstone's size. The karat mark of gold represents the percentage of pure gold to alloy.

  • 24K is pure gold or 100% gold
  • 21K is 21/24ths gold content or 87.5% gold: In the United States, jewelry with this karatage or higher is rare. It is far more common in Europe, the Middle East and Southeast Asia.
  • 18K is 18/24ths gold content or 75% gold: This karatage is a popular high-end choice in the United States, Europe and other regions. Its popularity is spreading throughout North America.
  • 14K is 14/24ths gold content or 58.5% gold: This is the most common gold karatage in the United States because of its fine balance between gold content, durability and affordability.
  • 10K is 10/24ths gold content or 41.7% gold: This karatage is gaining popularity for its affordability and durability. Commonly used in everyday-wear jewelry such as rings, 10K gold beautifully withstands wear and tear. It is the lowest gold content that can be legally marked or sold as gold jewelry in the United States.

    In order to determine the karat weight of a specific item, simply look for the quality mark. Jewelry items will bear the stamp of their karatage based upon the United States or European system of marking. The United States system designates pieces by their karats—24K, 18K, 14K, 10K, etc. The European system designates pieces by their percentage of gold content. For instance, 10K gold is marked “417,” denoting 41.7% gold; 14K is marked “585,” denoting 58.5% gold; and 18K is marked “750,” denoting 75% gold; etc.

    Diamond:

    The value of a diamond is determined by the Four Cs: Cut, Color, Clarity and Carat weight.

    Diamond Cut
    The cut of a diamond (the depth, width and uniformity of the facets) determines the stone’s brilliance and sparkle. Even if a diamond has perfect color and clarity, a poor cut can make it look dull. A diamond’s proportions determine how well the light will reflect and refract within the stone, with symmetry of the cut being extremely important.

    Diamond Color
    Acting as a prism, a diamond can divide light into a spectrum of colors, reflecting light as colorful flashes called fire. Color within a diamond diminishes the brilliance of the stone by diminishing the spectrum of colors that are emitted. A colorless diamond disperses light throughout the entire stone. Therefore, the less color that is in a diamond, the more colorful its fire, the better its color grade, and the greater its value (and priced accordingly). Diamond color is graded using an alphabetical range from D-Z (D being totally colorless). Diamonds graded better than J are colorless or near-colorless, with color that is typically undetectable to the unaided eye. Color K-Z is especially noticeable when set in platinum or white gold.

    Diamond Clarity
    Most diamonds naturally have small internal flaws called inclusions, which interfere with the passage of light through the stone. The size, number, position and color of these imperfections determine a stone’s clarity grade.

  • FL (Flawless): No internal or external flaws
  • VVS1-VVS2 (Very Very Slightly Included): Very difficult to see inclusions under 10X magnification
  • VS1-VS2 (Very Slightly Included): Inclusions are seen under 10X magnification, but not typically visible to the unaided eye
  • SI1-SI2 (Slightly Included): Inclusions are highly visible under 10X magnification and may be visible to the unaided eye
  • I1-I2-I3 (Imperfect): Inclusions visible to the unaided eye

    Our diamonds have been evaluated and graded by GIA graduate gemologists using the standards established by GIA (The Gemological Institute of America). Through these guidelines, we no longer provide clarity grades for SINGLE cut diamonds.

    Diamond Carat
    Carat is the standard unit of measurement used to determine a diamond’s weight. Although two diamonds may have the same carat weight, their color and clarity may be different, thus determining each individual stone’s value. Additionally, since larger diamonds are more rare than smaller diamonds, diamond value tends to rise exponentially with carat weight.

    More About Diamonds
    The most precious of all gems, diamonds have an incredible rarity factor. It takes a minimum of one million diamonds to be mined in order to find a 1.00ct gem-quality diamond, so each 1.00ct quality diamond is literally one in a million. Making them even more incredible, the mining of diamonds requires moving and sifting 250 tons of the Earth’s crust to find just one diamond. Mining companies literally move mountains to find diamonds.

    Diamonds have the longest endurance of any substance known on Earth. Carbon dating has established that diamonds, on the average, are 3.4 billion years of age. They consist of pure carbon and there is no chemical difference between them and carbon powder (the lead pencil center). Obviously, however, the physical difference between carbon powder and a diamond is fascinating. Diamonds are created from a basketball-sized piece of pure carbon that becomes white-hot. It is squeezed to the size of a small pearl, turning from black to clear in the process and becoming the hardest material known to humans, ranking a 10.0 on the Mohs Scale . Because they are so hard, diamonds can only be ground and polished by using diamond dust that has been ground from other diamonds.

    Diamonds are found in a rainbow of colors. The value of a fancy-colored stone depends largely on the rarity of its color, the saturation of the color, and the purity of the color. Probably the most famous colored diamond is the Hope, which features a deep-blue color and weighs an amazing 45.52ct. It can be seen at the Smithsonian Institute in Washington, D.C.

    With diamonds found all over the world, America has a couple small producing diamonds mines, but it only produces industrial grades with non-gem grade material. These black and brown industrial-grade diamonds are widely used as cutting and grinding tools in various industries, such as oil drilling and stone carving.

    Diamonds have come to symbolize the ultimate gift of love and romance and, in the United States, are traditionally used in engagement and wedding rings. The tradition of the diamond solitaire engagement ring may have started in 1477, when the Archduke of Austria gave a large solitaire diamond to Mary of Burgundy for her hand in marriage. Amidst this tradition of romance, the diamond is also the birthstone for April and given as 10th, 30th, 60th and 75th anniversary gifts.

    Diamonds have been the pride of empires throughout time. Ancient Hindu followers believed diamonds were created by thunderbolts striking the ground. Ancient Greeks believed that diamonds were teardrops of the gods and splinters of stars that had fallen to Earth. The stones were believed to possess magical qualities and have powers far beyond the understanding of common man. Even the name stems from “adamas,” the Greek word for “unconquerable” and “indestructible.”

    The diamond is considered the most magical of all gems. When worn, it is believed to promote spirituality, even ecstasy, and is often utilized in meditation. The diamond promotes self-confidence in relations with the opposite sex and is often worn to conquer infertility. The diamond is the stone of love and is worn to ensure fidelity. Owing to its sparkling and flashing nature, it has long been regarded as a stone of protection and peace. It can be worn today for courage and strength, and represents fearlessness and invincibility.

    Since only diamonds can scratch other diamonds, it is important to wrap and store your diamond jewelry pieces separately so they do not touch one another. To clean jewelry at home, soak diamonds in warm, sudsy water made with any mild liquid detergent. Brush with a soft toothbrush and rinse and pat dry with a soft, lint-free cloth. Other effective cleaning methods include soaking diamonds in household ammonia, brand-name liquid jewelry cleaners, or even a glass of vodka.

    White Gold
    Although gold is most often thought of as having a soft, yellow glow, the metal is available in an entire spectrum of different hues. The different colors of gold depend upon with which metals the gold is alloyed, or mixed.

    Increasing in popularity in recent years, white gold has become fashionable as the preferred cool and contemporary look. White gold boasts the same properties as classic yellow gold, but achieves its white color by mixing with different alloys. In general, white gold is created when a nickel or palladium alloy (zinc and copper) is used. White gold may also be plated with an even whiter metal, such as rhodium, to enhance its cool appearance. As well, a white gold setting can enhance the rapture of white diamonds.

    Emerald
    The symbol of spring and rebirth, the emerald has a color of green that communicates harmony, love of nature and a primeval joy of life. The word emerald was derived from the French “esmeraude,” which comes from the Greek root "smaragdos,” meaning simply “green gemstone.” For centuries, emerald green has been the color of beauty and eternal love. Even in ancient Rome, green was the color dedicated to Venus, goddess of love and beauty. Many cultures and religions today hold a special position for the color. For instance, green is the holy color of Islam; all states of the Arabian league sport green banners symbolizing the unity of their religion; and green is among the liturgy colors in the Catholic church. The emerald gem is May’s birthstone, and it is the traditional gift for couples celebrating their 20 th and 35 th anniversaries.

    Emeralds come in a variety of light and dark shades of green, often with subtle background hues of other colors such as yellow, blue, brown or gray. Most often, the purer and richer the green color, the more valuable the stone. Flawless emeralds are exceptionally rare, and therefore command great prices (even higher than diamonds, in some instances). Most naturally grown emeralds, however, have numerous inclusions that weaken their structure and cloud their color. F laws and cloudiness, called “jardin,” are very common in emeralds, so many are treated in some way to remove surface flaws and enhance color. The most common technique is to oil the stone with a green-tinted oil that strengthens the stone and fills in surface cracks.

    Emerald gemstones have been prized for thousands of years for their lush green hues and rare beauty. Venus, the goddess of love, is said to have loved the stone, and ancient Romans associated the emerald with her because it symbolized reproduction. Nero is said to have watched the Roman games in the coliseum through a set of highly prized emerald glasses. It's also said that Isis, the mother goddess, wore a green emerald on her headband. Supposedly, all who looked upon it would be able to conceive and were guaranteed a safe trip through the land of the dead. The gem is also considered the magical stone of forest spirits (elves).

    In ancient Egypt, emeralds were mined close to the Red Sea. This tranquil green gem was highly prized by priests and the wealthy, and it is said that Cleopatra loved it more than any other gem. In fact, gemstone mines called “Cleopatra’s Mines” were exploited by Egyptian pharaohs between 3000 and 1500 B.C., and were found empty when they were rediscovered centuries later. Even the ancient Incas and Aztecs in South America, where the best emeralds are still found today, worshipped the emerald as a holy stone. With the conquest of South America by the Spaniards in the sixteenth century, emeralds became more plentiful in Europe. Pizarro and Cortez took over the existing emerald and gold mines of the Inca and Mayan civilizations. They shipped these fortunes back to Spain, who in turn shipped them to trading ports throughout the world, turning Spain into one of the leading world powers of the time.

    Phrases about emeralds appear in the Veda, ancient sacred writings of Hinduism, including “Emeralds promise good luck” and “The emerald enhances your well-being.” Treasure chests of Indian Maharajas and Maharanis contained wonderful emeralds. One of the largest emeralds in the world is the "Mogul Emerald.” Dating back to the year 1695, it weighs 217.80 carats. One side is inscribed with prayers, while the other side is engraved with opulent flower ornaments. This legendary stone was auctioned off at Christie’s of London for 2.2 million U.S. dollars to an anonymous buyer. Other famous emeralds include a cup made from pure emerald that was owned by Emperor Jehingar. It is currently located in the New York Museum of Natural History, as is a Colombian emerald crystal weighing 632.00 carats. The entire collection is owned by the Bank of Bogota and contains five valuable emerald crystals weighing between 220.00 and 1,796.00 carats.

    Throughout the ancient world, emerald symbolized eternal hope, rebirth and the arrival of spring. The ancients ascribed numerous magical and mystical properties to this most precious of green gems. It was believed to give a person psychic powers, in that the gem could tell if a lover’s affections were true. Some cultures believed the gem rewarded its owners with love, intelligence, eloquence and a soothed soul. Middle Age seers used emeralds to foretell the future, as well as to ward off evil spirits and cure ailments ranging from bad eyesight to infertility. During the Renaissance, emeralds were used as a test for friendship among the aristocracy. It was believed that an emerald given to a friend would remain perfect as long as the friendship endured. The stone was also said to improve memory and bring great wealth to its wearer.

    Emeralds have long been thought to have healing powers, especially for eyesight. It is said that in business, emeralds can be used to promote sales and cash flow. It is also used to attract love by quickening the heart. The emerald is believed to put one in touch with the mind and have positive effects on psychic powers. It is said to increase those powers when used in meditation. Wearing an emerald bracelet on the left wrist is said to protect you when traveling in forests.

    Brazil is by far the world's largest producer of emerald, with a wide range of quality. The finest emeralds have traditionally come from Colombia, but Russia's Ural Mountains also have produced top-quality gems. Other sources for the stone include Afghanistan, Australia, Egypt, India, Pakistan, South Africa, United States, Zambia and Zimbabwe. Emeralds belong to the beryl group of stones. They have large, perfect, six-sided crystals with a hardness of 7.0-8.0 on the Mohs Scale.

    Tanzanite:
    No other gemstone discovery has made a bigger impact on the jewelry market than the recent newcomer, tanzanite. Its luscious color, and the fact that the stone is found in only one location throughout the world, makes tanzanite an exceptionally rare, valuable and highly sought-after gem.

    Tanzanite’s mesmerizing saturation of color is what has made the stone so popular. It is the blue variety of the mineral zoisite and occurs in a beautiful range of colors. Rarely pure blue, the gem almost always displays signature overtones of purple. In smaller sizes, it tends toward light tones such as lavender, while in larger sizes, the gem typically displays deeper, richer blues and purples. The finest quality tanzanite is usually deep blue or violet, which is extremely spectacular in sizes above ten carats.

    Tanzanite is pleochroic, meaning it shows the appearance of several colors in the same stone, depending on perspective. From different angles, the gem can appear blue, purple, yellow, grey or brown. Most rough crystals show a large proportion of brown shades, since tanzanite in its natural form is typically brown with red, orange, yellow or bronze hues.

    Gem cutters may change this coloring by heating the stone to 500°C. This heat treatment releases the intense violet-blue colors for which the stone is famous. According to legend, the effect of heat on tanzanite was first discovered when brown zoisite crystals were caught on fire by a lightning strike. Local cattle herders noticed the beautiful blue crystals sparkling in the sun and picked them up, becoming the first tanzanite collectors.

    The gem was first discovered near the base of Mount Kilimanjaro in the Merelani Hills of east-African Tanzania in 1967. This breathtaking location is the only known mining site on Earth for tanzanite. Right after its discovery, New York jeweler Louis Comfort Tiffany was presented with the first stones. Knowing it was going to be a sensation, he recommended finding a new name for the gem, since the gemological denomination “blue zoisite” reminded him of the word “suicide.” Tiffany suggested the name tanzanite, derived from its place of occurrence, and the new name quickly became established on the market. Tiffany & Co introduced the stone to the public in a spectacular promotional campaign two years after it had been discovered. It was enthusiastically celebrated as the “Gemstone of the 20th Century.”

    A noted 122.70ct faceted tanzanite dubbed the “Midnight Blue” is on display at the Smithsonian Institution in Washington, D.C. In 1996, a 255.00ct tanzanite crystal was discovered near Arusha, but because of its many inclusions, it proved to be of little market value. Tanzanite ranks a hardness of 6.5-7.0 on the Mohs Scale and has become the traditional gift for couples celebrating their 24th anniversaries.

    High-quality and larger-size tanzanites can be sold at extremely premium prices. Although demand for this beautiful gem continues to grow, supply shortages in recent years have hampered production and caused price fluctuations. In 1998, the weather phenomenon known as “El Nino” soaked Tanzania with heavy rains during what should have been the drought period. When the monsoons hit, the groundwater swells were high and caused devastating floods. Mines caved in and all hopes of finding additional tanzanite rough were swept away.

    Because it is such a new gemstone, there is little folklore, superstitions or healing properties surrounding tanzanite. Some believe the stone helps people to be more practical, realistic and honest. It is thought to uplift and open the heart while helping one cope with change.
