What is a properly proportioned gemstone and why is it important?
We get asked often “what is a properly proportioned Gemstone? ”
In general it is a stone that has a 1/3 crown and 2/3’s pavillion with a thin, but not sharp, girdle.
Why is this important?
With our mountings being pre-notched, you are not cutting the seat in the mounting. This is why having a properly proportioned gemstone is important. More than likely if your gemstone is very deep or very shallow it will not sit properly into the mounting, which can put it at risk of damage or loss.
