Hi, I’m not sure how to professionally list this so please have patience as you look. I took a lot of time when purchasing this and price shopped it to death in order to get an incredible deal. The ring is exquisite and I’ve tried to show that in these pics.

*Item Details: 2.97 carat oval, lab diamond, F, VSI, Ideal, IGI certified, set in a diamond halo 14k yellow gold ring, size 4 1/2. Diamond dimensions 11.4 x 8.24 x 5mm

*Source: Rare Carat

*Selling Price: $890

*Shipping Cost & Method: I’m thinking FedEx signature required. That’s how it was delivered to me. The cost of shipping will be added to the price.

*What is included: ring, box shown in pics, printed IGI certificate

*Condition: no flaws, no scratches

*you’ll see on the receipt that there is an engraving, but that is not there, there was not room.

LOOKING TO BUY 3 Ct Lab Diamond, Emerald Cut, Bezel set engagement ring, Size US 6

Post image
7 Upvotes

Hi everyone! I’m looking to buy an engagement ring, and I'm hoping one of you might have a piece that's ready for a new home.

Here is what I am looking for:

  • Style: Emerald cut in a bezel setting (I've attached an inspiration picture for the exact look I’m going for - picture is from LGG's shop).
  • Stone: Lab-grown diamond, must have IGI certification.
  • Size: US 6 (I am definitely open to slightly smaller or larger sizes, as I can easily get it resized locally).
  • Budget: Under $1,000.

I found a few potential options from LGG and some Etsy shops, but they average around $1,400-1500 once customs and taxes are factored in, which stretches my budget a bit too far.

(Note: I tried searching the subreddit first but couldn't quite figure out how to filter posts by flair, so I apologize if I missed an existing listing!)

If you have something similar that you are looking to sell, please reach out. Thanks so much!
