An emerald cut does the opposite: the open, mirror-like facets slow everything down so you can actually see into the stone, and on this piece that means watching blue and green separate across different facet planes instead of blending into one tone. Paired with the fact that it's unheated, with GIA finding no indications of heat treatment, this is a genuinely uncommon combination of cut, color, and treatment for teal material.\" — Ahmed Shareek, Crescent Gems\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eRarity Analysis\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003eTeal is already one of the less common sapphire colors — most sapphire production skews toward blue, pink, and yellow, with teal representing a narrower slice of what comes out of the ground.\u003c\/li\u003e\n\u003cli\u003eThe emerald cut (step cut) on teal material is a genuine format rarity: the large majority of teal sapphire is cut as oval, cushion, or round specifically to maximize brilliance and even out color.
