Clear Unmounted

Where can I buy synthetic alexandrite?

I am looking for cut synthetic alexandrite (unmounted) gems, with a clear red-green color change (not color change corundum or the purplish-bluish-greenish specimens). Does anyone know of a manufacturer or retailer (it’s fine if it’s online) for synthetic alexandrite?
P/S: I have been looking for this information but I can’t seem to find it. I know Creative Crystals (in California) makes it, but I do not know about the quality – haven’t been able to find a website for them. Thank you very much!
Manufacturer’s names would also be very helpful. Thank you.
