- (b) **The treatment creates special care requirements for the gemstone.** The seller should disclose that the gemstone has been treated and has special care requirements. It is also recommended that the seller disclose the special care requirements to the purchaser; or
- (c) **The treatment has a significant effect on the stone's value.** The seller should disclose that the gemstone has been treated.
