7.4 Carat Fantasy Cut Color Changing Blue/Purple Umba Sapphire, 11.1x10mm
This listing is for the depicted loose gemstone that I personally precision cut on my lapidary equipment
• Massive at 7.4 carats • 11.1x10mm 8.3mm in depth • Cut in my own dodecagonal Fantasy design with a compass cut crown • Untreated • Naturally occurring • Corundum (sapphire) • Unique attributes: Extremely rare size and clarity. This stone has some visible imperfections but it does not detract from the appearance. NO HEAT! A color shift to a medium purple/lavender is observed under warm tone spectrum lighting. Also distinct pleochroism from a dark to a light hue is observed on the tilt.
Unique attributes: This sapphire is the largest sapphire I have ever faceted. The cut and color are exceptional, this sapphire has a bluish purple hue with a medium tone and vivid saturation. It is dichroic, when tilted to one angle it shifts to a lighter color hue. Magic material, will not disappoint.
