For most of recorded history, rubies have been the most valuable gems. Rubies are very rare: it’s almost impossible to mine flawless rubies and many mined rubies are enhanced with heat and fracture filling to improve their appearance. Our lab Grown Chatham rubies have an almost pigeon’s blood color and exceptional clarity worthy of this gem’s ancient name, King of Gems.
