Found a stone I like. It is SI2 GIA cert. IF there are inclusions that break the surface of the stone or the girdle of the stone would the GIA cert tell me so?
I hope my question is clear because I''ve searched PS and not found an answer. THANKS
No, the major labs are pretty remiss in this respect. The only surface breaking characteristics which you can spot using a major lab report is a chip or a cavity. Otherwise it''s a guessing game. You have no idea if a feather is internal or surface breaking. No idea what the threat level of a surface breaking feather is, if any. No magnified photos to give you an idea.
I know with EGL certs looking at mine that internal inclusions are marked in red and external in green, not sure if this is the same for GIA certs,but someone else may be able to tell you for sure with GIA certs. For example, naturals which are small areas around the girdle that some cutters can add to hit a certain carat weight are marked on the cert. The appraiser or vendor will give you a better idea. The best thing to do is to be careful with surface breaking inclusions in any case, but your vendor will be honest with you, particulary if you are buying online and advise you if there is a surface break which might be a durability concern. Not all SI2 diamonds have surface reaching feathers etc or large obvious inclusions, they need to be taken on a case by case basis, but your vendor or appraiser will be the best person to help here. Also in any case an independant appraisal is always a good idea to check the diamond out, for $120 as a very rough figure, it is a small price to pay for peace of mind and online vendors will encourage you to do so. If you find a great SI2 that is great, some here have fantastic and eyeclean diamonds in that clarity grade. Probably best to get an expert to verify for you.
I asked the saleslady about this and she said that the GIA report would tell me if an inclusion broke the surface. She gave me a copy of the GIA report. I guess she didn''t know that it won''t tell me.
With checking for surface reaching inclusions I wouldn''t advise trying to decide about them yourself, really for your protection that is best left to the appraiser.
