Customer Care + Craft = 💯
Ordered my fiancé’s engagement ring and there was a tiny issue with the addresses… I thought Christmas proposal was ruined 😭. But it showed up on Xmas Eve morning and I got to propose!! Super happy with the quality and how fast it got here.
Hassle-Free!!
Ordered a made-to-order amethyst bracelet for my mom. The stones are gorgeous and the design looks exactly like I imagined. There was a slight delay with shipping since I ordered it during Holiday season, but the team kept me updated the whole time. Mom was thrilled and I will definitely buy from them again!
GO FOR GEMNAT!!
Okay, jewelry addicts… the quality of these pieces is insane. Bought an eternity band elsewhere for double the price and it looked nothing like these. Gemnat has me hooked!!
OMG!!! MY GF CRIED WHEN SHE OPENED HER GIFT. BEST PURCHASE EVER
Love it
OMG this is literally PERFECT!! Exactly what I’ve been hunting for. It got to me crazy fast, the packaging looked super fancy, and ordering was a breeze. Customer service was super friendly too. Honestly, I’m blown away, can’t believe how smooth and amazing the whole experience was!
I have wanted a ruby since I was a little girl.
Now I finally have it and at 5cts this ruby is an absolute STUNNER!! I asked them to customize the design since I wanted a bigger stone than the 1ct they had on the page and they totally made it happen!! Had it set on a 1.5mm white gold box chain for extra strength and that perfect sparkly but classic vibe!! I’m SO in love with it!! Yay me!!!
Nice! Great quality, would definitely buy again.
My son gave this to his girlfriend and she was thrilled! It’s so dainty and gorgeous.
My new go to place when it comes to diamonds!
I'M OBSESSED!!!
My husband got it for my birthday and I am seriously obsessed!! The pink sapphire is so bright and sparkly, way prettier in person than I ever imagined. It fits perfectly and I get compliments on it literally every day!! I can’t stop staring at it, it’s just so gorgeous!!
My husband bought me this beautiful ring for our 10 years anniversary, absolutely stunning! Mine is 0.53 carat white gold and it goes well with my engagement and wedding ring together.

I’ve had nothing but great experiences here. The quality of the jewellery is excellent
a 101% RECOMMENDED!!!
I’ve been planning to propose to my girlfriend for months, but I was terrified of choosing the wrong ring online 😅. I wanted something meaningful, unique, and perfect for her. She loves sapphires, so I started looking for one that would make her eyes light up. I stumbled upon Gemnat and honestly, I didn’t know what to expect. I ended up customizing a sapphire engagement ring with a slightly larger stone than the standard, and I kept imagining her reaction while biting my nails. When the ring arrived, I was blown away by how beautiful it was the stone sparkled like nothing I’ve ever seen, and the craftsmanship was impeccable. On the day I proposed, she literally gasped, had tears in her eyes, and said yes while covering her face. I’ve never seen her so happy, and the ring looked even more stunning on her than in the pictures. Gemnat made the whole process smooth, from customization to shipping, and even helped me with sizing questions. I can honestly say this was the most important purchase of my life, and it couldn’t have gone more perfectly. Thank you for making this moment unforgettable!
It’s elegant without trying too hard.
It came slightly big but customer service fixed it sooo fast!!
If I could give more than 5 stars I would! You can’t go wrong with GEMNAT, they have amazing pieces and excellent quality. I can’t wait to get my next purchase from them again
What You See Is What You Get!
I'm super happy with my 1st purchase here at Gemnat. I would give them 10 stars if I can! They are HIGHLY RECOMMENDED!!
I wear this literally all the time now. It’s simple but diamonds make it look expensive af. Gemnat’s sizing guide was actually helpful, and support answered a quick question I had about chain length. Packaging was neat and delivery was on point.
YAYYY!!
I wear this every day, and it still looks brand new. The pink sapphire catches the light so beautifully. Would definitely buy again!
I was scared about quality but it exceeded expectations.
Worth the WAIT!!
I was a bit anxious waiting for it to arrive, but once I saw it, I was truly impressed by the quality and beauty. My wife absolutely loved it and it looks amazing on her. I’m very happy with this purchase and would definitely recommend this site to others.
