Thermal Only, Treatment, for corundum gems

This is a grade for Thermal treatment only ! On a GRS certificate or GemResearch Swisslab. It states the ruby is only subject to H treatment or H (a) is also acceptable.

@TomC what is the question? It just looks like you posted a series of statements.

The error as I wrote it, I missed. Apologies.
I will attempt to make the correction.
Correct is " Is this a new grade" for Thermal treatment only
