Agate Gold over Bronze Drops
Found all over the world, agate has been creatively striped by nature. It is a type of chalcedony quartz that forms in concentric layers of colors and textures. Each individual agate forms by filling a cavity in a host rock. As a result, agate often is found as a round nodule with concentric bands like the rings of a tree trunk. Tiny quartz crystals called druzy (sometimes spelled as drusy) often form within the stone, adding to its beauty and uniqueness. Agate is a hard stone, within the range of 7.0-9.0 on the Mohs Scale.
In 1497, the mining of agate in the Nahe River valley in Germany gave rise to the cutting center of Idar-Oberstein. When the Nahe agate deposit was exhausted in the nineteenth century, Idar cutters started to develop the agate deposits of Brazil, discovering Brazil's rich deposits of many other gemstones. A famous collection of two to four thousand agate bowls, accumulated by Mithradates, King of Pontus, shows the popularity of agate at the time. Agate bowls were also popular in the Byzantine Empire. Collecting agate bowls became common among European royalty during the Renaissance and many museums in Europe, including the Louvre, have spectacular examples.
Although the small town of Idar-Oberstein is still known for the finest agate carving in the world, today Idar imports a huge range of other gem materials from around the world for cutting and carving in Germany. Cameo master carvers, modern lapidary artists and rough dealers flourish there, exporting their latest gem creations. It is an entire industry that grew from the desire for agate products during the Renaissance.
Agate was highly valued as a talisman or amulet in ancient times. It was said to quench thirst and protect from fevers. Persian magicians used agate to divert storms. Today, some believe that agate is a powerful emotional healer and helps people discern the truth.
Pronounced "vermay," vermeil is an electroplating process in which 14K gold or higher is coated over sterling silver. Officially designated by the jewelry industry, items may only be sold as vermeil if they have a minimum thickness of 100 millionths of an inch (2.5 microns) of gold over the silver. Regular gold plating is less than 2.5 microns.
The "vermeil" technique of plating sterling silver with gold originated in France in the 1750s. It differs from "gold filled" or "gold plated" in terms of the thickness or thinness of the microns over sterling silver. "Gold filled" pieces have a much thicker layer, between 15 and 45 microns, which is mechanically bonded to the base metal with heat and pressure. Vermeil is a more expensive version of "gold plated". It does not wear off as quickly as gold plating does. However, over time, vermeil wears off and therefore will require re-plating.
Gold/Platinum Embraced Silver or Bronze:
Our platinum and gold embraced collections feature layers of platinum or 18K gold over sterling silver or bronze for a lustrous, radiant finish everywhere you look and touch.
To care for your plated jewelry items:
Remove jewelry before bathing, swimming, washing hands, putting on make-up, lotions, perfumes, and/or working with household chemicals, cleaners, or acidic liquids.
Do not clean plated jewelry in an ultrasonic cleaner or in silver cleaning solutions, as it could completely remove the plating finish from your item.
Ensure your jewelry item is thoroughly dry before storing. Moisture in an enclosed space can increase tarnishing.
Store your plated jewelry in a jewelry box lined with felt or anti-tarnish material. Items should not be stacked as this may cause damage to the plating surface.
Do not use excessive pressure when cleaning with a polishing cloth or soft brush, as this may cause damage to the plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
Earring Back Types
The backing is an important part of an earring, providing a secure closure and comfortable fit. Keep in mind, some earring styles work better with certain back types. Experiment with the different types to find the best fit for you!
Butterfly Back: A double looped piece resembling a butterfly that fits over a post. Variations on this design are called push back clasps. The basic post and butterfly back are usually used for stud earrings and lighter weight drop earrings.
Hinged Snap Backs: This clasp features a hinged post that snaps into a groove on the back of the earring. It is commonly found on hoops. Sometimes the hinged post is curved to provide more room to fit around the ear, sometimes called a saddleback.
Hook Backs: This earring backing is simply a long, bent post that fits through the piercing. Hooks have several variations, most notably the shepherd's hook and the French hook. While thin wire hooks reduce the weight of long earrings, making them more comfortable, they aren't as secure as other clasp styles.
Lever Back: A hinged lever snaps shut against the curved post to form a closed loop around the ear lobe. This clasp is very secure and good for large or medium sized styles that drop just below the ear.
Omega: Also called French clips, this clasp has a straight post and a looped lever. The hinged lever closes around the post and is held against the ear with pressure. The omega clasp is the most secure clasp, especially for the larger, heavier earrings.
Screw back: This backing is a slight variation of the standard post and butterfly nut back. Instead of pushing on the back, the nut twists onto the threaded post. A screw back post design is often preferred for expensive diamond stud earrings that require increased security.
