On the Mohs Scale, which measures the hardness of minerals, cubic zirconia is an 8.0 to 8.5. It is important to understand that hardness is not necessarily related to durability. Even though diamond is the hardest mineral (10.0 on the Mohs Scale), it can still be chipped or broken.
The only ways to tell the difference between cubic zirconia and diamond are by use of a thermal probe, by weighing the loose stone or by microscopic examination of surface features and inclusions. Cubic zirconia weighs approximately 65% more than diamond. Therefore, while a 6.25 mm round diamond weighs about 1.00 carat, the same size cubic zirconia weighs about 1.65 carats. If you know the weight of a cubic zirconia, you can figure out the diamond weight equivalent by multiplying the cubic zirconia weight by 0.6, or 60%.
Few natural diamonds on the market today are perfectly cut, and those that are cost much more than the usual diamond. Unleashing the fire, beauty and brilliance of a stone depends on its precise cut. Simulated diamonds are an excellent balance between quality, beauty and price.
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.
Stainless steel, also called corrosion resistant steel, is a steel alloy with added iron and chromium. The metal is low maintenance, rust-resistant, durable, highly lustrous and extremely hygienic, making it ideal for items such as cookware, knives, surgical instruments, jewelry and watches.
The nearly-indestructible and masculine nature of stainless steel is appealing for many jewelry styles. It has a similar appearance to platinum and polishes to a glistening sheen. Any scratches that may occur from day to day wear can be easily buffed away without endangering the piece. Unlike traditional gold, silver or platinum jewelry, stainless steel jewelry is not poured into molds, but is usually hand-cut from a solid piece of steel, leaving no seams or weak spots. With stainless steel, your jewelry will last a lifetime.
Stainless steel was first recognized in France in 1821 by metallurgist Pierre Berthier. He realized the iron-chromium alloys maintained resistance from acids and recommended their use in cutlery. After several corrosion-resistance related discoveries and patents in Europe and the United States, Harry Brearley in England discovered a modern blend of stainless steel alloy. When it was announced by The New York Times in January of 1915, he was officially credited with the invention of this impressive modern metal.
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.
