About Black Spinel
Black spinel is only found in a few locations in the world, and because of its rarity, if the demand were to rise, supply would not be abundant enough to keep up with it. It is not known how the name spinel originated, but some suggest that it may have derived from the Latin word 'spina,' meaning thorn, possibly referring to its fiery color or the sharp pointed crystals that are found within some spinels. A durable stone that lacks cleavage, black spinel is rated at 8 on Moh's Scale of hardness. Spinel is associated with love and helping the wearer become devoted to another person. It is also said to encourage passion and increase the duration of one's life. Black spinel, in particular, is said to be a protective stone that helps reestablish relationships.

Sterling silver, also called fine silver, is a beautifully lustrous cool-toned precious metal favored in fine jewelry among other products. The most reflective of all metals (excluding mercury), sterling silver looks stunning by itself and brings out the best hues in an array of colorful gemstones.
Sterling silver can be polished to a higher sheen than platinum. In fact, Ag, the chemical symbol for silver, comes from a word that means “white and shining.” The surface of silver can boast that shiny, polished appearance, or can be brushed, satin, matte, sandblasted, antiqued or oxidized (chemically blackened).
In order to be called sterling silver, a metal must be made up of a minimum of 92.5% pure silver and 7.5% alloy (meaning other metals), including but not limited to copper and nickel. The alloy is added to pure silver to make the metal more durable, tougher and harder. Sterling silver is designated a fineness of “925.” Pieces with sterling silver may be marked “sterling.”
Finishes on Sterling Silver
Finishing, or plating, is a common treatment with sterling silver. Popular types of plating are rhodium plating, gold plating and anti-tarnish plating. Plating is used to extend the life and sheen of the jewelry. After sizing or buffing a piece of jewelry with a machine, it must be re-plated to restore the finish.
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.
