Natural Untreated Ruby / Red-Pink Sapphire. 1.3 cts. Umba Valley, Tanzania

$2,600.00

This vibrant 1.3 carat ruby / red-pink sapphire is natural, better than eye-clean, unheated, and untreated. It has been polished to competition grade in an original modified radiant cushion cut. Exceptional color for such material from this region. This gem has a color profile right at the cusp of the cross-over from the most vibrant red-pink sapphires into the red primary realm of ruby. In natural day light this gem to our read sits squarely with red as its primary color and appears to us to classify properly as ruby. As such a call in the gem industry involves a subjective color read with experts often not in agreement in cases on the cusp, we are listing this also as “red-pink sapphire.” This is a stellar gem.

Better than eye-clean with some rutile rod inclusions under loupe magnification in direct sunlight as is typical for corundum from this region. Videos:
