If you are looking for a deep electric blue gem, this is it. It does have a darker body tone so in lower lighting environments it will appear opaque with electric flashes of blue as it catches the light. Please review the low-light videos in the gem clip (on hand) before deciding if it's a good fit.  Even with the darker tone, it's a stunning sapphire in my opinion.

Detailed Gem Description:

A natural and heat-treated zoisite var. Tanzanite with a dominant violet hue, a medium tone, and moderately strong to strong saturation.  This is an open-tone gem, it will glow and sparkle in any lighting!

See the last graphic for reference on how I graded these. To maintain originality, I made the reference graphics with gems of my own design but it is based on GIA's color description system.

Photos were taken in daylight and under a microscope.  The first four videos were taken in daylight with the sun overhead and a blue sky. The last few scenes in the fourth video are inside in passive lighting and under my overhead LED lights. The outdoor scenes in the fifth video were taken on an overcast day.   Please review all the videos thoroughly.

Gemstone Rough Country of Origin: Tanzania
Cutter: Indigo

• Microscopy Report:
This gem has one healed secondary fluid inclusion, It can be seen on the flat edge opposing the point.  It looks like a milky white streak. The reference photos were taken in 4x magnification under direct and darkfield illumination. 

• If you would like this gem for a custom jewelry project, you can reserve it directly from this listing, follow up with the details for your custom project, or purchase it bundled with a pre-priced setting.

• A GIA lab report can be ordered for your purchase, see the "GIA laboratory report listing" for details
