Difference between thin & med girdle

[glenn925]

I have found a diamond that rated a 1.8 in the cut advisor...But the rating is based on a vg polish and med girdle,,,The diamond I am interested in has a thin girdle,,,but an exc polish & sym!!! It is an H&A diamond...Should I worry about it having a thin girdle??

Hi Glenn, Thin girdle is not affecting beauty of the diamond. Tolkowsky described his ideal diamond with Extremely Thin - Knife Edge girdle.AGS ideal proportions allow Thin to Slightly Thick girdles.The only problem with a thin girdle is a higher chance to chip it.As for better polish and symmetry, it shouldn't hurt you at all

In an otherwise proplery cut stone, the thin girdle will have little adverse effect on durability and will have no effect on appearance. A thin girdle combined with a shallow crown angle contributes to a decrease in durability allowing girdle chipping and larger breakage to more readily occur.------------------

A thin girdle gives max spread and reasonable protection against chipping.
Very thick girdles have little impact on beauty - but a big impact on spread because there is additional weight at the thickest part of the stone.

a thin girdle is virtually NO DIFFERENT than a medium. it is no more or less appealing,has NO effect on the beauty or brillance, and is absolutley NOT more likely to chip more than a medium, AND it is quite unlikely that even well experienced diamond appraiser could look at a diamond girdle and be certain whether the GIA would call it a thin girdle or a medium....THE DIFFERENCE is EXTREMELY microscopic.
but for those who are enthralled with such minutia, a THIN girdle is generally prefered, similarly to a very small or no culet being prefered.

What I've read most is that Very thin to Extremely thin girdles are to be avoided in fear of chipping during setting or daily wear.It seems reasonable to me-diamonds are expensive and there are so many out there (in general). I would prefer to err on the side of safety.lawmax

Good link Leonid-that information is not so easy to find.
