Girdle single stone competition “Master”

[oliviers]

Hello,
I am surprised that this year the thickness of the girdle is 0.5 +/-0.1mm for Master. In past years it was 0.3? I just wanted to know what was the reason for its increase? would the “standarts” change?
Thank you.

It was felt that the thicker girdle is better if you intend to set the stone later. There have been complaints about the too-thin girdle in the past.

Hi Oliviers – the measurements for the 2020 competition stand as published, but will likely revert in 2021. This is being discussed now by the competition committee.
