I need 10 1.75mm white saphires for a project I am thinking
about doing - but have been unable to locate any stones of this
Stuller stocks white sapphire in that size. The run about $1.20
each according to thier catalog. If you want them matched it may
be a little more, I'm not sure. You can probably get them cheaper
elsewhere, but I don't know that it is worth the effort to look
for stones this inexpensive. Stuller phone: 1-800-877-7777
Hope this helps.
