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. Chatham's lab-grown rubies have a pigeon's blood color and exceptional clarity worthy of this gem's ancient name ratnaraj: King of Gems.
Since 1938 Chatham has stood for quality, reliability, and integrity.
Our commitment to excellence ensures that each gemstone meets the highest standards of quality and craftsmanship before they reach your hands.
That is why we stand behind our lab grown gemstones through our lifetime warranty.
