Unheated 44.36 Carat Yellow Sapphire Pear, GIA, Pendant, Enhancer, Collector Gem
By Sarosi By Timeless Gems
Located in Los Angeles, CA

It was masterfully cut to unlock its spectacular canary yellow color and maximum brilliance. The accompanying Gemological Institute of America Report #2141858703 states that this unheated gemstone...
