Treatment Slips
These are designed for clients who wish to have a clean gemstone without any enhancement, or wish to replace one enhancing substance with another, before having an identification or origin report issued. These Treatment Slips do not identify the nature of the gemstone, only the enhancement. This means that the gemstone submitted is not tested for its identity.
     There are two types of treatment slips:

  • T1: This treatment slip only states the extent of enhancement, without stating the nature of the substance. Fee: US$50 for AGTA members / US$75 for non-AGTA members
  • T2: This treatment slip states the extent of enhancement as well as the nature of the filler. 
    Fee: US$100 for AGTA members / US$125 for non-AGTA members.

     Fees apply every time a gemstone comes back for recheck.
