Bought at the source
Jay has traveled the world seeking the finest gems, from being one of only a few Westerners permitted into Mogok Valley to find Burma rubies, to traveling with armed escorts into Colombia’s Muzo emerald mines. These adventures made Jay one of the most powerful buyers in the world, capable of finding the rare and precious jewels that Astrological Gem is known for.
What makes a Jyotish gem
Color
Each gem species has a wide range of color. The gem’s quality of color, its tone and its modifying shades matter most.
Clarity
Free of eye-visible flaws, and free of black inclusions even at 10 to 20 times magnification.
Cutting
A well-cut jewel whose sparkle delights the eye and pleases the heart.
A sweet, sattvic feel
You can’t see it, even through a microscope, yet it is one of the most important qualities of a fine Jyotish gem.
