Hi! I recently bought a custom piece with a colour-changing stone that was sold to me as “alexandrite” (likely lab-created), and I’m trying to figure out how to verify what it actually is.

From photos and videos, it shows a noticeable colour shift (blue/green in daylight to pink/purple in warmer light), and it’s faceted and pretty clear. But I know lighting and cameras can sometimes make things look more dramatic than they are.

I’m not expecting it to be natural alexandrite, just want to confirm whether it’s genuinely lab-created alexandrite vs a generic colour-change synthetic or glass.

What are the best ways to tell at home?

•	Are there specific lighting tests I should do?

•	Any visual signs I should look for in the facets or colour shift?

•	Or is the only reliable way to take it to a jeweller/gemologist?

Would really appreciate any advice or things to check 🙏
