Customer Reviews
Solid tennis bracelet
Got a lab grown diamond tennis bracelet. Quality is good. Shipping was fast. Item was exactly as described. No complaints.
Really pretty necklace
I got one of their lab grown diamond necklaces, the solitaire pendant, and it's super nice. It came in a cute little box and got here pretty fast. I was a bit worried about buying jewelry online but it was a good experience.
Good ring, minor delivery issue
I bought a white gold pave engagement ring during their spring sale. The ring itself is beautiful and looks just like the pictures on the site. The lab-grown diamond sparkles nicely, and the craftsmanship seems solid. Shipping was free, which was great, but it took about 10 days to get to me in Oregon, which felt a little long compared to other online purchases. I had hoped it would arrive a bit quicker. Customer service was polite when I inquired about the shipping status, but they couldn't speed it up. Still, good value for the price.
Great value on my first purchase
As a first-time buyer, I was looking for the best deal. I signed up for their newsletter and got a first-order discount on a pair of lab-grown diamond hoop earrings. The discount brought the price down to something I felt comfortable with for fine jewelry. Shipping was free, which always helps. The earrings are really pretty and feel well-made. For what I paid, I feel like I got a really good deal on quality earrings.
Detailed review of my purchase
I ordered a 1.5 carat round brilliant lab-grown diamond for an engagement ring setting. The ordering process on their website was straightforward, with good filtering options for the diamonds. It shipped within a week and arrived securely packaged via FedEx, requiring a signature. The diamond itself came with IGI certification as promised, and its quality matched the specs listed online. I did have a question about the color grade, so I used their online chat support, and they were responsive and helpful, providing clarity. Overall, the transparency and product accuracy were impressive.
My new earrings are amazing!
I absolutely love my new lab grown diamond stud earrings! They sparkle so much and look fantastic. I was so excited when they arrived, it was quicker than I thought it would be. I'm definitely telling all my friends about Modern Gem. I'm already planning my next purchase!

trying to figure out shipping times to like, Dallas. Is it usually quick or should I expect a wait for an engagement ring?
hey, anyone know if Modern Gem does military discounts? looking for an engagement ring for my fiancé.
Thinking about an oval cut ring, but I'm worried about sizing it if it's not perfect. Is that something they handle?
can you stack multiple discount codes at Modern Gem? like a newsletter one and a holiday sale code?
does Modern Gem do financing, like Affirm or something? A big purchase like a ring would be easier spread out.
