Wondering if anyone can help. I have an old appraisal for a diamond dated 5/1981. It reads:
Ladies solitaire diamond ring set in a 18 Kt. yellow gold mounting. The "Radiant" cut diamond wieghs 52/100 of a carat, with a quality of #2 color and #2 clarity per G D C Grading. This is a FINE quality diamond.
Can someone tell me how this "G D C Grading" compares to the current diamond grading standard? Or should I take the stone somewhere to get it certified/graded?
Any help will be appreciated!
