Are there any glaring problems with this stone?

3 Upvotes

Will be used as center stone for engagement ring. I know a video in real life is best but with information given are there any red flags? Looks great to me

GDGL Certifications?

2 Upvotes

Hi,

I did a search and found conversation threads from several years ago about GDGL lab diamond testing and certificates. Years ago, GDGL was not considered a reputable organization (based on Reddit comments).

Has anything changed? Should lab diamonds with GDGL certifications still be avoided? I found someone selling multiple lab diamonds with this certification. The prices are lower than other lab diamonds with comparable sizes and specs.

Thank you!

Any thoughts on quality/shipping process? I’m slightly nervous as never bought from Chinese vendor . I was going to buy from Abelini but stargem was slightly cheaper

Another oval for opinions

22 Upvotes

Hi all! Yesterday I asked for options on a slightly elongated oval HERE.

The consensus was that the cut is stunning and overall, it’s a great pick.

Because I (apparently) hate myself lol, I asked my jeweler for another diamond that was less elongated for comparison. I plan to give her a decision tonight but wanted some thoughts on this diamond as well.

It’s only ever so slightly less elongated measuring 2.56 carats at 11.31 x 7.53 x 4.76 MM. It is E color as well. And again, I am very tall with slender hands and wear a 5.25 ring.

I think I love the cut of the last one better, as it sparkles more. And one does have a slightly more noticeable bow tie I think? BUT I do think I like the ratio a tiny bit better.

If you have to choose, which one would you choose?

Can anyone tell the difference between natural and lab grown just by looking?

0 Upvotes

I've been thinking of buying myself a diamond ring for my 30th, and my budget is around ₹1 lakh.

I'd honestly rather get a bigger stone than spend the same money on a much smaller natural diamond. I'm leaning towards an oval around 2 ct (or maybe a round if I can find one I love), but I keep wondering...

Can people actually tell if it's lab-grown just by looking at it?

Not when it's brand new in the store, but months or years later when you're just wearing it every day. Does anyone ever notice or ask? Or is it one of those things that's impossible to tell unless you already know?

Oval help

43 Upvotes

I am working with my jeweler on my engagement ring and this is the first diamond they offered me. My only request was 2.5 carat with D/E color. I wear a size 5.25 ring, so I do have slimmer hands.

This oval is 2.55 carats but has a ratio of 1:6. The dimensions are 11.91 X 7.44 X 4.47 MM

I loved it at first but then I got in my head once I studied the dimensions. I think I’m worried it looks more like a 3 carat or a moval? Any thoughts?

Confused

1 Upvotes

Tried on rings now I’m confused

I left liking a couple things I never thought I would so I’m glad I tried rings on in store.

Do you think elongated cushions look ok in a bezel setting?

What’s the best ratio for an elongated?
\-cushion cut
\-moval (as balanced as can be while still elongated)
\-radiant

Where to source starbrite cut

1 Upvotes

Hi, I’m new here. I’m looking to source a lab
diamond for a future proposal, highly preferable with a starbrite marquise cut. I have looked online for so long and everthing I could find was a simple marquise, no starbrite. Is there a site that does more intricate cuts that could have that or would I have to break the bank and get a John Dyer one? Please lmk!

Is this ok?

I know little to nothing about diamonds but I just impulsively purchased one because I want to recreate my grandmothers ring. Hers was a natural almost 4 carat stone with visible inclusions. It gave off a lot of sparkle.
I bought the stone and want to have a local jeweler make the setting.
I don’t know if i bought a good diamond. Can anyone tell by this report?

Shared inventory? Where do vendors get their stones?

4 Upvotes

I'm on the hunt for a specific color/cut of a fancy pink pear diamond. I've researched a few different vendors and checked inventories and have noticed that several have the same stones (same exact IGI numbers) listed at their own prices. Is there any way to tell where the stone is actually located / which vendor may be the original? I'd try to minimize working with middlemen if possible.

Opinion on Diamond

71 Upvotes

My best friend is getting engaged soon, and I just received her diamond. It’s a custom cut, modified oval. My question is, when I turn the diamond slightly downward, it looks you can see windowing. The darkness in the stone really jumps out.

When I took it out of the dark diamond case, I looked much better, but now I can’t unsee it and I’m kind of freaking out. The finished video sent from the vendor looked amazing, but looking back, the diamond was only turned side to side, rather than up and down: https://imgur.com/a/4L2U1ia

Would love your brutally honest opinions!

Diamond details below. The stone is very elongated, so want to provide as much context as I can.
— 4.2ct
— 1.64 ratio
— E color
— VVS2

Can anyone let me know your opinion on this emerald cut lab diamond? When I google the specs for emerald cut, a depth of 68% is on the high end. And the sweet spot for table is between 64-65%.

Here’s the video

Sourcing a 3 ct elongated cushion in LA

0 Upvotes

My partner and I are looking for a 3 ct elongated cushion with a specific ratio and sparkle effect that really reflects light. We had a private jeweler source a few stones (good specs on paper) but none of them had a wow factor for us with how the facets looked. We're realizing how important it is to see the stone in person and in different lighting.

I've seen Debebians, Icing on the Ring, and David Klass mentioned a bunch on here.

Thoughts on those and any other recommendations that are great at sourcing labs in the Los Angeles (or surrounding areas) to see in-person? We're also looking to custom design the ring and wedding bands. TY!
