> Synthetic rubies and sapphires have been around for over 100 years and are dirt cheap ($10 for a 15mm one on eBay).
Rubies are much cheaper than that.
At least, I used to order them from Pehnec Gems at prices more like $3 per (in lots of 10+). I haven't bought them in years and pehnec.com currently resolves to 10.0.0.1; not sure what's going on.
