Physical Properties of natural earth-mined Sapphire
Sapphire is the Birthstone for September and naturally occurs in every spectral color. Ancient Greeks and Romans believed that Sapphire was symbol of wealth and wisdom; they also believed it would bring the wearer success in the affairs of the heart. Sapphire is a very hard stone and wears extremely well. Here are the specific qualities of the sapphire: Crystal Structure: Hexagonal, Refractive Index: 1.717, Density: 3.98-4.1g/cm3, - Hardness Mohs: 9, Chemical composition: Al2O3SiO2 (Alumina Silicate Mineral)
Sterling Silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver standard has a minimum purity of 925. Jewelry Works had developed a proprietary sterling silver alloy that is superior at holding its shape and tarnish resistance.
Fine silver, for example 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength. Sterling silver is prone to tarnishing, and metals other than copper can be used in alloys to reduce tarnishing, as well as casting porosity and firescale. Such metals include germanium, zinc, platinum, silicon, tin or boron.
