Please help me estimate the carat of this ring - thanks very much!

[noyu]

Hello everyone, first time posting here, please let me know if I should post to somewhere else and thanks in advance for your opinions.

This is the e-ring that my fiancé proposed with. The ring is actually bought by his family (a cultural tradition) and he doesn’t know the details and the certificate was with the future in-laws in a different country... I love this ring but I got so curious about the 4Cs... didn’t feel right to ask the future in-laws, so if you can help me get an idea of the carat at least, that would be great.

The finger size is 6.5.

Thanks again!

Looks bigger than mine which is 1/3ct but beyond that I’m not good at guessing

If you have a caliper to measure it the stone, you can plug into calculators online for an estimate — but ct is a weight measurement so two diamonds with exact same dimensions will be slightly different in ct

The best thing to do is measure in mm, and then check a mm to carat conversion chart, it will give you a rough estimate. It’s impossoble to tell from the picture but I would guess half a carat or so depending on the depth maybe a bit more. But it’s a very of guess like that.

With your fingers being a 6.5 (hello to all of us who don't have enviably teeny tiny fingers....) it might be a bit more than 1/2ct. But the best thing is to get a rough measurement. You could also go to an appraiser on your own in your city and have them look the ring over for you and give their opinions on the 4C's for you, which should include some basic measurements.

~5mm is generally around 1/2ct
~5.75-6mm is generally in the 3/4ct area

You can probably pop into any jewelry store and just ask them to measure it with calipers for you to get an idea.

I second what others have suggested about visiting a local jeweler.

I have size 6 fingers and my guess based on your finger coverage would be somewhere between 1-1.25.

Please come back and update us, I would love to see how accurate our guesses end up being.

Looks like a De beers ring. What does it say inside the ring???

 

[Kaycee2018]

Impossible to tell, but it looks about .75-.90 to me.

 

[Rose-gold-or-bust]

Inside the band, are there any numbers?

Yes, based on your finger size, I would think the diamond is apx 2/3 - 3/4 carat or so ...

If you have a ruler and can measure the diameter of the diamond, a 2/3 carat diamond is apx 1/5th of an inch, and a 3/4 carat diamond is just under 1/4 inch. Some standard rulers also include metric measure, and if yours does, just determine the diameter of your diamond in millimeters. Then do an internet search for a chart of diamond carat weight based on diameter mm.

By the way, your ring looks beautiful on your finger - congratulations!

I was thinking around 3/4 but a jeweler would be your best resource.

Thanks so so much for all your responses! Those are great suggestions! I haven’t had the time to go to a jewelry store but I’ve used the ruler tape and the diameter seems to be 6.0-6.5mm.

 

[Rose-gold-or-bust]

6mm would put you around .8 ct — close anyway. It’s so hard to tell exactly with a ruler and ct is a weight measurement anyway so it could be a .7 with more spread than usual or a 1ct that’s a little dense

OMG yes!
It said D1.07ct and d0.15ct

I think it means center stone 1.07ct and stones on the band 0.15ct problem solved.

I do think it looks somewhat smaller though! Oh well I don’t have slender figures anyway

Thanks again everyone!

Many of them will give you an "opinion" on color or cut quality, but if you want more information with actual measurements of the stone and a gemologists opinion, you'll need to pay an independent appraiser.

maybe .65?
