What was Stress supposed to do to a diamond again?

[pyramid]

I know that many experts believe that Stress is only of concern in a diamond during the cutting process. I cannot remember and was wondering what it was that those other experts thought stress would do to a diamond after cutting! Was it that cracks would appear in the stone where there was none before?

No idea about these two camps, but it must take lots of wear and tear to match the preassure a diamond is submitted to during cutting and polishing.

BTW, 'stress' seems to mean at least two different defects in diamonds. Depending on context, stress is 'something' that makes diamonds either less white or more included or less durable. In all cases, this sounds like a classical 'scare' (= diamond shopper's stress

) rather than gemology. Do you know of a good electronic source explaining what is diamond 'stress' ?

Thanks valeria101. I was trying to read the previous posts, but I thought it was not due to wear and tear but that a crack could develop within a diamond due to strain whether the diamond was worn or not. i.e. it was going to happen anyway. Maybe I read it incorrectly before as I cannot find that part again.


Electronic Source? all I have heard about are looking through a polariscope and then what the human believes.

Anyone know if it was said by those that believe it, that strain in a diamond can cause cracks to appear even if the diamond is not worn?

Thanks strmrdr.

Wouldn't the stone cleave along a natural fracture line? Which could be an inclusion becuase it causes weakness in the structure around it - or just a weak point due to geometry and geo. formation.? It would depend on the type of stress (could you give an example)? Traumatic or constantly increasing pressure could do this but I can't think of an everyday scenario that would subject a stone, in a ring say, to that kind of pressure. Just an amateur. Someone with know how should answer this one.

I think I imagined that they just cracked without any impact or stress as I cannot find it now. This has been debated many times on diamondtalk.com and on this board but it seems that most experts believe it is only a problem in the cutting process and that after that let insutance worry about it.

Regarding the type of stress, I recall in the other threads that people mentioned getting rings trapped in doors and filing cabinets and also said that rings do go through a lot of stress if worn on a daily basis.

I do not thing any one really wants to talk about this as it has been discussed so many times and there are plenty of threads on the newsboards which would just duplicate it. There is no proof as no one wants to break up expensive diamonds to find anything out.

Thanks Pyramid - still a newbie! I haven't checked all those threads - Good point about the testing. Personally, I am willing to leave it to insurance for now. Cheers.
