Try contacting Ladyrockhound.com I believe she has some. She had at least 20 jars but she showed me a trick using a lazer light for clarity and to see inclusions. $15 I believe. She is the one that makes the italdo diamond spray. Good Luck.
I know that Refractol is no longer being distributed, but I have been distributing a replacement, “ImmersAll” for about six months. Contact me by email, I’ll send you pics and info. 2 oz bottles, 4 oz jars and kits including an immersion cell and a set of polarizers. My email is email@example.com and I am on FB under Wayne Emery.
Try wetting your stone with common hand cleaner like “Germ-X” sold at Wal-Mart. You may be surprised as to how well you can see inside. If nothing else you will have a clean germ free stone when through.
Hi Nancy, I recently attempted to find Refractol for a new faceter. I wasn’t able to get any from the sources that listed it. So, I did some homework and found that there is a really good replacement that is less messy and safe to use. It is Benzyl Benzoate, RI 1.568. This is available in 50 ml bottles at several online chemical suppliers. It is way less expensive than Refractol and less smelly too. I am no longer using my last bottle of Refractol after using this better disclosing liquid.
