Flux Grown vs. Flame Fusion Video

Rubies and sapphires both belong to the gem species corundum. It is the presence of the trace mineral chromium that gives rubies their rich red color. Rated 9 on the Mohs scale of hardness, rubies are very durable making them ideal for use in jewelry.

Eco-Friendly Chatham lab-created rubies are not fakes, rather they are REAL rubies grown in a laboratory. With Chatham, you get top quality, top color rubies for a fraction of the price of natural rubies.

Vedic Astrology and Chatham Rubies

Chatham rubies are flux grown rubies that grow in the natural crystal structure of corundum. This means they began with a natural seed crystal. Many believe Chatham stones still have the essence of the natural crystal in them, so they are powerful for purposes of Vedic Astrology. Ruby is often prescribed when Sun needs strengthening.
