Question for Professional Diamond dealers/jewellers

[pyramid]

I have seen the experts many times saying if part of a girdle is extremely thin/very thin as long as it is only a tiny part the diamond will be okay.

1. Is this just because there will be less of the area to chip or does it mean the diamond could be proportioned okay?

(I realise if the whole girdle was extremely thin the possibility of damage would be far greater.)

2. However, when giving this advice does this not mean that the diamond being bought will have a WEAK SPOT?

3. Why buy a stone like that? Why do cutters cut diamonds with these dangerously thin girdles?


I know they try to save diamond rough but other manufacturers would make alterations to pieces if they were of inferior quality.

Diamonds have been worn for a long time with very little breakage from any "problem" that most have in some form or another. They are not unbreakable, but they really are extremely durable. A tiny area of very thin girdle is a weak spot, but it is a very tiny one. It is likely not to become damaged. You can insure against that happening and the insurance company will not charge you any extra since they do not base their premiums on "risk", but on a very generalized scale that is simply based on total retail value.

When you consider the many possible weaknesses in a diamond, those of you who have a super stone really are paying a higher premium than you deserve to pay and those with a risky stone are getting a better deal than the diamond deserves. Of course, this is hypothetical, since insurance coverage on diamonds is NOT risk based.

"Don't worry" may sound like an easy thing for a seller to say. Most of the time it is proper advice, although, there could be some limited cases where worry might be fair.

Thank you Oldminer, I was forgetting about insurance.

However, why do cutters cut diamonds with dangerously thin girdles?
