Where do I find these dime sized rubies for 20 bucks?

[–] gravitas_deficiency@sh.itjust.works 2 points 2 years ago (1 children)

Right? A dime is a touch over 18mm, and prices I’ve been able to nail down on a couple sites for artificial rubies of that size, while way less than terrestrial rubies, cannot be considered ”cheap” - we’re still talking thousands of dollars.

Maybe they mean ruby infused grinding wheels?

Or maybe they were exaggerating a little bit and thinking about ruby bearings.

I searched lab grown rubies and these guys seem to be pricing near to that cost. They seem legit from a cursory search but i haven't looked that deep.
