JOYA Moissanite by Judy Crowell 17" 9 x 6mm Lab Created Sapphire Necklace
Platinum can be used as a finish coating over sterling silver or copper alloys. Its bright, pure luster enhances the brilliance of gemstones and does not discolor or oxidize. Platinum plating is also characterized by its good resistance to surface abrasion, making jewelry pieces more durable against everyday and long-term wear. Over time, platinum plating will wear off and therefore will require re-plating.
To care for your plated jewelry items:
Barrel Clasp: Used on most rope chains to make the chain more secure. The barrel clasp looks like part of the chain and twists to get a pendant on and off.
Lobster Claw Clasp: As a traditional clasp style found in bracelets and necklaces, the lobster claw is generally reserved for heavier styles that may need added strength. The closure's shape is more oblong, similar to a teardrop shape, and is controlled by a tip that opens and closes the spring in the clasp. This type is also considered a more expensive finding that can add to the overall value of the jewelry piece.
Magnetic Clasp: The popularity of the magnetic clasp has greatly increased in recent years. It is a quick and easy way to secure jewelry while not having to fuss with a tiny clasp, which can be difficult if you have long fingernails, arthritic hands or other mobility challenges. A magnetic clasp relies on a strong internal magnet that works to pull both ends of the clasp together. In most cases, a magnetic clasp is used for light to medium weight jewelry pieces that do not put excessive stress on the magnet.
S-Clasp: An S-shaped piece of metal that connects a chain by hooking metal rings on each end of the S-shape.
Slide Insert Clasp: This type of clasp is exactly as it sounds. With a box-like shape that is hollow on the inside, the wearer will slide the nearly-flat tab into the box until it clicks, indicating a secure closure. On some jewelry, a slide insert clasp will be accompanied by a side safety catch, which adds strength and security to the clasp. Although this type of clasp is found on both bracelets and necklaces, it is particularly popular on bracelet styles. These types of clasps are often reserved for more expensive jewelry.
Spring Ring Clasp: One of the most common closure types, the spring ring clasp is typically used for light to medium weight bracelets or necklaces. It is round in its design and features a small tip which controls the opening and closing of the spring. The circle then closes around another smaller loop or link at the other end of the strand.
Toggle Clasp: A toggle clasp is a narrow piece of metal, usually designed in the shape of a bar, which is then pushed through a circular ring to act as a fastener. Unlike the lobster claw or spring ring clasps, a toggle clasp is not controlled by a spring. The pretty design is less secure than other closure types, but is usually meant to be a big part of the design and is meant to "show". The clasp is an attractive way to secure a chunkier link bracelet or necklace.
The length of a necklace or chain you buy depends upon a number of factors, including what you will be wearing with it and your neck size.
To measure your neck, wrap a soft, flexible tape measure around the base of your neck. This is the same measurement used for collar sizes in men's shirts. A good rule of thumb is to buy a necklace or chain a minimum of two sizes up from your neck measurement. Thus, a man with a 17" neck would want to skip the 18" size and get a 20" size to ensure a comfortable fit.
Appropriate women's necklace lengths are more dependent upon the style than neck measurement. Knowing your basic neck measurement, though, will help you decide what length will work best with your outfit and create the look you are after.
Created Moissanite has very high dispersion and displays 2.4 times more fire than diamond (0.044). Its inherent high refractive index gives Moissanite a dazzling sparkle, while its precisely calibrated and carefully hand-cut facet patterns intensify fire and maximize brilliance.
Moissanite is extremely durable. It is harder (more resistant to scratching) than ruby or sapphire – second only to diamond – and it is resistant to breakage.
Larger sizes of near-colorless Moissanite (6.5mm or 1 carat and larger) might appear to have a slight color. A variety of factors, such as dispersion, tint and the type of jewelry setting, can create and affect this unique color appearance. Moissanite aficionados enjoy the slight hue that results in a very natural-looking gemstone, even though it's lab-created.
Moissanite’s high dispersion produces flashes of rich rainbow (spectral) colors. The appearance and degree of these tints are less noticeable when Moissanite is set in jewelry. Jewelry set in gold (yellow, rose or white) and/or set in platinum will affect the face-up appearance of Moissanite.
Nobel Prize-winning chemist Dr. Henri Moissan discovered minute quantities of natural silicon carbide (later named Moissanite in his honor) while analyzing part of Arizona’s Diablo Canyon meteorite crater in 1893. Upon close inspection, he noticed the tiny crystals shimmered with brilliance and dispersion, although they were too limited in quantity and not large enough to use in jewelry.
Almost 100 years after Dr. Moissan's amazing discovery, a way to create Moissanite was developed. Appreciated for its overwhelming brilliance, Moissanite continues to take the jewelry world by storm.
Brilliance: The white light leaving a jewel, traveling upward, which is visible to the eye. Brilliance is sometimes referred to as "sparkle."
Dispersion: Flashes of rainbow colors. Also called "fire."
Hardness: Resistance to scratching. The higher the number, the more resistant.
Luster: The shininess of a jewel.
Toughness: Resistance to breakage.
Created or Simulated Gemstones: How are created or simulated gemstones different from natural gemstones? Natural gems are created by the forces of nature and must be discovered, usually by digging in the ground or sifting through a riverbed. When these stones are created in a laboratory, they are called created, simulated or synthetic gemstones.
The purpose of creating gemstones in a laboratory isn’t necessarily to reduce the cost, but also to produce larger, more perfectly consistent stones. Created or simulated gems can be made of any material. Synthetic gems, however, share virtually all chemical, optical and physical characteristics of their natural mineral counterparts.
Austrian Crystals: These are known for their excellent reflective quality and prismatic brilliance. This man-made crystal is created using natural minerals and quartz sand, which are then heated and slowly cooled using a process similar to that of creating hand-blown glass. This process creates an end product that can be fashioned into a beautiful crystal.
A special machine is used to create a highly faceted crystal. The crystals are cut in various directions, which allows for excellent light refraction, exceptional brilliance and unsurpassed color quality at an affordable price.
Today Swarovski® is one of the largest suppliers of high-end crystals. In the late 1800s, Daniel Swarovski invented a machine to cut crystal with extreme precision. He patented his technique and to this day, only select Swarovski family members and employees have unrestricted access to the production facility that creates these crystals. They are used to decorate everything from stilettos and sculptures, to chandeliers, jewelry and clothing.
