This listing is for the depicted loose gemstone that I personally precision cut on my lapidary equipment
• 4.24 carats • 11.3mm in length, 7.9mm in width and 7.2mm in depth • Cut in my own fantasy octagon design • No Treatment • Naturally occurring • Corundum (sapphire)
• Gemological description: A natural tourmaline with a greenish blue and yellowish green hue both visible. It has a medium tone and vivid saturation. This is an open tone tourmaline, it will glow in any light! The multi hue appearance is from pleochroism, the AB axis of the tourmaline was greenish blue while the C axis was yellowish green. Imperfections are visible but don't detract from the appearance.
Gemstone Rough Country of Origin: Democratic Republic of the Congo
