Mine’s GIA & I have no experience with any other labs, but your post caught my attention (I also stalked you from the other thread :P)
Have you thought at all about getting a stone with flourescence? Buying a stone with flourescence can also reduce the cost of the stone. It is a risky property for jewlers because some believe that flourescence can make a diamond cloudy in about 10% of diamonds with flourescence-others say that it doesn’t at all. Most jewlers buy via the cert, and never see a the diamonds they purchase ahead of time, so they don’t want to risk a stone being in that 10%. As such, the stones sell for a bit less than the same stone would without flourescence.
My stone has strong blue flourescence, so not only was it less expensive than if it didn’t have that property, but it GLOWS under UV light! It is not cloudy at all, and by far my favorite thing about the stone is the flourescence. (Pic below- one of the accent diamonds has flourescence as well). Additionally, it will make some lower color grades appear more colorless and enhance the beauty of the stone. Lower color grade=more savings. Mine’s a J, and it lookes white white. (The two most important things to me were cut and carat size by far- no one is asking you if you have a G colored ring, anyway)
I also noticed that you were debating between getting a Ring Bearer v. an oval around 2.5 cts.
Let me start off by saying that I LOVE ovals. When we were first designing my ring, I knew I wanted an oval- there was no doubt in my mind at all. I drooled over Katie Holmes and Blake Lively’s rings- there wasn’t another option for me. So we had a jewler bring in several ovals, ranging from 2-3 cts. I hated them all once they were actually on my finger! I realized that I was missing the finger coverage that I wanted and needed at least a 4ct to get the look I desired, and I have never been a fan of halos. I’ve seen some women on here with gorgeous ovals, but on my finger, they looked awkward and small.
I’m not saying this to scare you away from ovals, but before you do too much thinking, have a local jewler order some stones for you (virtually no jelwer has ovals of that size on hand) so you can have a look.
Cost-wise, they are about the same, but ovals are a much riskier shape to buy for.
I’m not sure if you are considering online at all, but Adiamor was GREAT! My rep drove to see several stones in person for me so she could make sure they weren’t cloudy. She drove something like 2 hours each way for the stone I ended up getting, and called me when she was there so I could ask her questions about it!I don’t believe this is the common practice, but I was impressed because I thought I’d have to limit myself to James Allen! They also constantly notified me of new stones that fit my criteria before they hit the website.
Adiamor also works with a lot of uncommon metals (mine is palladium, which is the cheaper version of platinum & the metal Iron Man uses in the movies… they also use 19k white gold (they are currently not providing this option to all customers just yet), which is in between platinum and white gold cost wise- the special alloys in the 19k white mean that the metal is naturally white and never has to be rhodium dipped). Buying online also means no sales tax and more competitive prices.
Adiamor’s diamonds are also all certified conflict free, one thing that you may not be able to trace using another grading scale
Idk- I think I’m going through withdrawl because I spent months researching stones and metals- and I have no new rings to perfect. (Although I noticed you asked about the width of my band, personally, I would go for a 1.9mm if I had to do it all over again). Probably more info that you were looking for, but I was just like wow-she seems to have similar tastes and be in the same position as I was a year ago (I may have stalked your post about oval/rb cost :P)
Best of luck!
