I came across an eternity band ring with each diamond slightly less than 1 carat. However, the jeweller said that at that size they don't come with GIA certs. I don't believe that because I bought a pair of earrings years ago, each was about 0.7 carat, and each was accompanied by a GIA cert. Does anyone know above which carat do diamonds come with certs?
 
I think that is perfectly reasonable. Some stones just don't have certs. The reason behind it is based on the jeweler's decision - sometimes a jeweler is targeting at a clientele that wants more of a guarantee and hence needs a cert for every stone, or another targets a client who just wants a bracelet that looks nice enough but doesn't care about the cert. There are good quality diamonds around without certs and not-so-good diamonds with certs. It is not necessarily based on carat weight. Usually diamond eternity rings and bracelets are built by "competent-looking" diamonds that don't require a cert, but I've also seen such items come with certs for each stone. I've seen certified diamonds that are less than .5 carat. 0.7 studs, a total of 1.4 is considered a rather big purchase, so it will probably come with a cert. 0.7 is much bigger than the .10 carat stone (each, I guess for that design) for the eternity.
 
Thank you for the information! The eternity ring I saw had Asscher diamonds, EACH about 1 carat or slightly less. Maybe 0.9ish. It was around USD90K. Shouldn't that sort of price warrant a guarantee?
 
I worked at a high-end jewelry store a few years back and they issued certificates to diamonds of 1 carat or greater. Anything smaller didn't come with one. Unfortunately, I don't remember the reason why.
 
evekitti-----Check out the GIA website. A wealth of info there, including the fees.

Thanks! It didn't occur to me to check the GIA website. Apparently it doesn't cost a lot to get a diamond graded, a mere fraction of the price of what a diamond would retail for. I wonder why some jewellers don't bother doing it. Surely, it'll help convince a potential client.

Thanks again steelsapphire for the tip.
 
What the jeweler may mean is that under 1 carat the GIA does not issue certificates, it issues GIA documents, an abbreviated kind of paper. But he is being disingenuous since he is not offering you that either.

You have to be the one to decide whether or not you want to spend $90K without knowing exactly what you are getting. that's what GIA certs (or AGS, they're just as good) do for you. The in-house gemologist may be good but he/she does have some pressure on them to bump up the stones color and/or clarity just a little. They are not impartial like the independent gem labs. And with diamonds, they may look very pretty and also sometimes even the same to the naked eye, but there is a real price difference between a .95 carat and a one carat for instance, or between an F VVS and a G SI1.
to me, a good reason to forego a certificate i(EGL USA can also be okay, I wouldn't bother with IGI or some of the others) is if the diamond is really, really cheap, which is not the case here. You also are not going to have as good resale value (such as it is) without a certificate unless you have some name on the bracelet, such as Tiffany. So if I were you, in this case, I would go elsewhere.
