Natural Red sapphire

Natural Red sapphire are technically categorized as rubies, a kind of corundum (aluminum oxide), which derives its color from trace amounts of chromium. The term “natural red sapphire” is misleading.

Igneous rocks including syenite, nepheline syenite, and pegmatite contain corundum as a major mineral. The downslope soils and sediments contain some of the most significant ruby and sapphire deposits in the world, where the gems have weathered from basalt flows.

Unusual Characteristics
Red Sapphires advance in self-awareness, truth realization, and steady development on their life’s journey. It is a gem for government workers, farmers, politicians, and medical professionals who want to do well on competitive tests.

Therapy
The high-temperature electric furnace with an induction heating element was used to heat treat beautiful sapphires. Different temperature regimes are defined based on the gem material and the desired color of the sapphires after treatment. If necessary, a particular gas environment is also established by using specific reagents with varying redox strengths.

Uses for jewelry include pendants, necklaces, rings, studs, earrings, and more.
