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 and 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. Excellent clarity for material from this locality

Gemological Description: A natural untreated corundum (sapphire) with a dominant bluish violet hue, a medium tone and vivid saturation. Imperfections are visible. Notably fully formed rutile needles spanning the gem. This gem has a secondary bluish green hue visible on the tilt and has a notable color shift to a violetish purple hue indoors under warmer spectrum lighting. 

Gemstone Rough Country of Origin: Umba Valley, Tanzania
Cutter: Sennin
