Looking for a 3D Scanner for Gemstones

Good morning, guys.

I'm a CAD Designer and we already have a NextEngine Scanner.
This scanner is pretty great, but runs into issues when scanning reflective/refractive objects.

The suggestion from them was to coat the objects in a white film for them to become 'opaque' but that's not an option for some of the smaller gemstones we sometimes have to scan.
Are there scanners out there that are, say, under $7500 (preferrably $3000 or so) that have the capability of scanning gemstones or rings without having to coat them?

Thanks in advance.

What about mounting the gemstone on a clear "pedestal" and placing them in a glass of distilled water?

Would the reflections be dispersed to provide better clarity?

Just wondering...

I have never tried that, but I don't think I'll be able to keep distilled water clean in my current environment.
It would be an interesting experiment, for sure.

However, my superiors have tasked me with finding a scanner that can easily scan gemstones without a need to 'jank it', so, while I can probably test what you're talking about, anyone happen to know of such scanners?

You could use a touch-probe scanner; it doesn't care if the subject is reflective or clear. I've got a Roland MDX-20 I could sell for what you're looking to spend; it has a piezo touch-probe and also some milling functions. Message me off-thread if you want to discuss it.
