In stock


This beautiful unheated sapphire is a very pale shade of blue, appearing nearly colorless in person or under incandescent light.  The macro image shows one tiny inclusion but not visible without a 10x loupe–its an eye clean gemstone.

This sapphire is faceted in the classic diamond round brilliant design, cut to “hearts and arrows” precision.  It weighs 0.51 carats and measures 4.7 x 3.1 mm.  It would make an amazing center stone for a beautiful engagement ring!
