What is a Yemenite Ruby?

Hi

I'd like to find out what specifically a red Yemenite ruby is. I'm
trying to locate the stone in order to have a ring talisman made a
Xmas present for someone. Someone told me they think that it's also
called a Yasimite but I haven't been able to independently verify the
information. Unlike other rubies which would probably break if
engraved, this one should be engravable.

Any information on what exactly this species of ruby is, how much it
costs per weight and what other names it goes by would be most
appreciated.

Please email me at [EMAIL PROTECTED] if you know. Thank you.
