Many of the gems we offer are "Natural" and "untreated", but the majority of the gems on the market are routinely enhanced or treated in some way, so we have always been concerned in disclosing any treatments that we know may exist as well as the affect it may have on the gem you are considering.

We disclose the particular treatment that may apply to a particular gem, both in our online description as well as at the point of sale.
