Of course, whether or not to take on a gemstone repair job depends on the specific situation. As neophyte faceters, you’ll face these decisions. Personally, I don’t do repair work for the following two reasons.
First, by working on someone else’s gemstone, you open yourself to some liability. Things might go wrong, or the customer just may not like what you’ve done. Even if you made it clear up front that there’s no way to predict what will happen when you put a stone on a cutting lap, even if you made it clear the risk is theirs, you can still get sued. Admittedly, this would be an extreme case, but it does happen.
For example, a gem cutter friend of mine was sued over an emerald repair. You’ll find many emeralds out there in need of repairs, since most are poor quality. (Shocking, I know). In this case, the gem had a major flaw, which he pointed out to the jeweler. He informed my friend his customers (the stone’s owners) knew the stone had flaws and to proceed with the cutting. So, he did. The gem owners later claimed that cutting the stone made the flaw worse.…
