Pinctore Sterling Silver Blue Zircon, Sapphire & Diamond Halo Ring

Caring for Sterling Silver
Sterling silver becomes tarnished as the result of a natural chemical process that occurs when sterling silver is exposed to chemicals in the air, rubber, wool and latex. Humidity also plays a role in accelerating tarnishing. It's easy to keep your sterling silver sparkling, though, by taking a few steps to prevent tarnish and other wear and tear.

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.

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.

Sapphire:
An ancient Persian legend states the Earth rests on a gigantic sapphire that gives its blue reflection to the sky. The most popular colors for sapphires range from light blue to a blue that appears black. Hence, the name was derived from the Latin form of the Greek word for blue, "sapphirus." These blue colors are caused by iron and titanium in the stone. Bright daylight makes most sapphires shine more vividly than the somewhat muted artificial light. So the most highly cherished color for blue sapphires is not the darkest blue, but a deep and satiated blue, which even in dim, artificial light remains to appear blue.

While sapphires are best known for being velvety blue, it was decided long ago to consider all gemstones of the mineral family corundum to be sapphires. Non-blue sapphires are termed "fancy" and can be nearly any color, including yellow, green, white, pink, orange, brown, purple and even black. Red corundum is the exception, however, and was given the special name of "ruby."

In lighter-colored sapphires, the shade of color is determined by how the stone is cut. A cutter must take special care with sapphires. Not only do they rank a 9.0 on the Mohs Scale, second only to diamonds in hardness, but they display a different coloring and satiation depending on the perspective. The cutter must align the orientation of the stone in such a way as to bring about the best possible display of color.

There are a great number of varieties of sapphire, many of which are quite rare and highly sought-after in the gemstone market. A rare orange-pink variety, known as padparadscha, can be even more valuable than blue sapphire. Given the poetic name meaning "lotus blossom," it features a delicate orange color with pink undertones

Another rare variety of sapphire is known as the color-changing sapphire. This stone exhibits different colors in different light. In natural light, color-changing sapphire is blue, but in artificial light, it is violet. This effect is the same phenomenon seen in alexandrite.

For experts and connoisseurs, the Kashmir-color is considered the most beautiful and valuable shade. It features a pure and intensive blue, which is enhanced by a fine, silky gloss. Its color does not change in artificial light, but remains intense with a deep, velvety sheen. Setting the standard for the color of top-quality sapphires, Kashmir sapphires were found in 1880 after an avalanche. They were intensely mined for only eight years until the source was depleted. The Burma-color is also considered especially valuable, ranging from rich royal blue to deep cornflower blue. Ceylon sapphires are prized as well for the luminosity and brilliance of their light to medium blue color.

There is a translucent variety of sapphire, called star sapphire, which displays a six-point star when cut into a smooth domed cabochon. The mineral rutile is embedded in an asterisk-shape within the stone, causing light to reflect in a phenomenon called "asterism." Six- or twelve-ray stars appear to magically glide across the surface of the stones as they are moved. Star sapphires and rubies are expensive rarities and should always display the stars exactly in the center of the gem. The star stone is said to be the home of each person's angel, who lives there in contentment with the sapphire's spirit.

White sapphires have become a very suitable diamond substitute. With their high light refraction and level of hardness, they provide a less expensive alternative that is still very capable of turning heads with a very convincing sparkle.

The oldest sapphire mines are situated in Ceylon, where gemstones were mined in ancient times. Most blue sapphires today come from Thailand or Australia, but sapphires from Kashmir and Myanmar are highly prized. A large sapphire occurrence stretches across several miles in Madagascar. There are also two large occurrences in Tanzania, where smaller, yet high-quality sapphires are found. The stone is also mined in many other parts of the world.

Sapphires are readily available in sizes of up to 2.00ct, but gems weighing 5.00-10.00ct are not unusual. The cushion-cut Logan Sapphire from Sri Lanka weighs an astounding 423.00ct and can be seen at the Smithsonian Institution in Washington, D.C. There is also a 258.00ct stone set in the Russian crown, which is kept in the Diamond Fund in Moscow.

Because the gem has long symbolized sincere love and enduring faithfulness, blue sapphires are often given in engagement rings to express commitment and loyalty. Many women throughout the world decide on the blue stone for their engagement rings, as the gem also represents truth, friendship, harmony and consistency. Sapphire blue has become a color related to anything permanent and reliable, making it an ideal stone to symbolize the promise of marriage.

Often referred to as "Gem of the Heavens," sapphire also symbolizes a noble soul. It is September's birthstone and is traditionally given as 5th and 45th wedding anniversary gifts. Star sapphires are given for the 65th anniversary. The color sapphire-blue is known for representing clarity and competence. In fact, the first computer to ever declare victory over a chess grandmaster and world champion was named "Deep Blue."

Sapphires have been associated with magical powers throughout the ages. The Greeks identified white sapphires with Apollo and the oracles at Delphi used them to tap into the subconscious and super conscious. In the 13th century, it was said that when worn, sapphires cooled the inner heat of anger. Soldiers wore them to prevent capture by enemies and kings wore the gemstone to defend against harm and put themselves in divine favor. This supposed "divine favor" is why sapphires were often the gemstone of choice for high priests and royalty throughout history. In fact, the British Crown Jewels contain a number of notable sapphires.

During the Middle Ages, sapphires symbolized the tranquility of the heavens and wearing them was thought to bring peace, happiness and purity of the soul. Medieval priests and monks would wear sapphire jewelry believing it had the ability to quell wicked impulses and impure thoughts. The color blue became the symbol of the union between a priest and the heavens, so sapphires came to be adorned on the rings of bishops.

Today, sapphires are still believed to hold special powers. It can be considered an aid to psycho kinesis, telepathy and clairvoyance, while providing spiritual enlightenment and inner peace. White sapphires, like diamonds, are considered the guardians of love, enhancing it and ensuring fidelity in marriage. The most powerful type of the gem is said to be the star sapphire. They are believed to protect against negative energy and have a calming effect that allows the mind to experience tranquility, joy and clear thinking.

Zircon:
Zircon often suffers for its name’s similarity to “cubic zirconia,” the simulated diamond. The stone zircon, however, is actually a beautiful natural gemstone. It is named from the Persian word “zargun,” meaning “gold-colored.” This is despite the fact that it comes in a wide range of rainbow colors . The majority of zircons are brown or yellow-brown, while pure red and green are the most valuable colors. The yellow-red to reddish-brown variety is called “hyacinth.”

For many years, the most popular type of zircon was the colorless variety. More than any other natural stone, colorless zircons produce a brilliant sparkle similar to diamonds . The most popular color today tends to be the bright pastel blue variety. Sometimes called “starlite,” blue zircon has recently become considered an alternative birthstone for December.

Zircon is one of the heaviest gemstones, meaning that it will look smaller than other varieties of the same weight. It ranks a hardness between 6.5-7.5 on the Mohs Scale and is mined in Cambodia, Sri Lanka, Thailand, Myanmar and Australia.

Travelers during the 11th century wore zircon amulets for protection and to encourage welcome greetings on their journeys. In the Middle Ages, the stone was said to bring wisdom and prosperity to its owner. Hindu mythology even mentions the gem when referencing the Kalpa Tree, which was a glowing tree covered with gemstone fruit and leaves of zircon.
