synthetic corundum and spinel gemstones

SYNTHETIC (LAB CREATED or LAB GROWN) CORUNDUM & SPINEL GEMSTONES

SYNTHETIC CORUNDUM:

          When someone lists the most famous gemstones, corundum does not usually get mentioned. However, its two varieties are sure to be on any list of gemstones. The red variety of corundum is known as ruby and all the other colors of corundum are usually called sapphire. No wonder that there have always been attempts to imitate natural precious stones, especially those which are most highly valued, like ruby and sapphire.

Natural corundum or aluminum oxide mineral (Al2O3) is the second hardest natural mineral known to science. The hardness of corundum can be partially attributed to the strong and short oxygen-aluminum bonds. These bonds pull the oxygen and aluminum atoms close together, making the crystal not only hard but also quite dense for a mineral made up of two relatively light elements. Synthetic corundum has all the properties of the natural mineral, but is much cheaper than its natural counterpart, which allows it to be used not only as a synthetic gemstone, but to also have a number of industrial applications. 

Our synthetic corundum is available in two shapes: half-boules and full boules and in a number of different colors.

SYNTHETIC SPINEL:

          When someone lists the most famous gemstones, Spinel does not usually get mentioned. However, its two varieties are sure to be on any list of gemstones. The red variety of corundum is known as blue spinel and all the other colors of spinel. No wonder that there have always been attempts to imitate natural precious stones, especially those which are most highly valued, like ruby and sapphire.
