JOYA Moissanite by Judy Crowell 1.25" 1.00 DEW Solitaire Drop Earrings
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:
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.
Earring Back Types
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.
