What is the Best Synthetic Corundum International Gem
There are many ways to synthesize gem-quality corundum both ruby and sapphire gems. Flame fusion is the least expensive method of synthesizing any stone. Hydrothermal synthesis is the most expensive. This involves growing a crystal from a solution under great heat and pressure.

Flame Fusion Gemstone Synthesis from YourGemologist
There are other indicators of synthetic corundum by flame-fusionbut you should not attempt to make a call for syn -v- natural using these methods until you are well experiences with known stones. The first is fluorescence. Due to the absence of iron in most synthetic rubies they tend to react much brighter to UV light than naturals.

· Table 1 details the occurrence of corundum inclusions in Juina diamonds and summarises the mineralogy and geochemistry of diamond hosts and associated mineral inclusions. Three inclusions of ruby have been recovered with one 60-μm sample (BZ241C) being a touching grain with a high-Al (10 wt. ) Mg-pyroxene (BZ241B1).
Synthetic SpinelGemstones Guide
· Synthetic spinel continues to be made for several reasons. First because it is slightly softer than synthetic corundum it can be fashioned more rapidly and less expensively. Secondly several of the colors in which it is made are better imitation for a number of natural stones than those made in synthetic corundum.
