Hello,
First post here and no expert on gemstones so I'd appreciate any thoughts on a vintage brooch I have.
The gemstone is lab created as too perfect but I'm just trying to figure out if it's colour change sapphire or alexandrite. At first I thought it was just glass but Presidium went straight to the line between sapphires and diamonds. The colour change is very difficult to capture in the photos but I hope these give some idea:
1) daylight outdoors
It does have shades of bluish/greenish colour in daylight.
2) incandescent light. It changes to a slightly warmer and more saturated purple.
It glows emerald green along the edges under UV light, brighter and greener than in the photo but I cannot photograph it properly.
Any ideas? Thank you!
