What Customers Are Saying
They could not have been more helpful and professional and we were amazed with the service. Happy to recommend anyone who’s considering diamonds online
They are ABSOLUTELY TRUSTWORTHY!!!
These earrings are so simple but legit sparkle like crazy. Perfect for everyday or when I wanna look fancy. Website was smooth, shipped fast. Obsessed.
There customer service is very very patient when I had a problem with resizing. The ring that I order was a bit smaller but no need to worry since they had it resized for me. Everything was SMOOTH. Will definitely order from this shop again for sure.
The website is so user-friendly. You can easily access everything you want from rings, bracelets, pendants and earrings even wedding rings. They even sort out the colour of stones for buyers. All the designs are super nice it even makes me had a hard time to choose what to buy but I really wanted a tennis bracelet during that time but would probably buy a ring for my girl next time. They are highly recommended!! Customer service was nice because I have to make some adjustments with the chain length and they were patient on every process. Fast replies. Thank you, GEMNAT!!!

Outstanding customer service and experience. It is already our 2nd time buying a ring here and I always got what's expected. Very beautiful ring!!

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.
