Carateu Avis 

The order experience was very simple and nice to use. I could design my own ring just the way my soon to be wife would like it. There is plenty of options to chose from, and the diamond selection was very beautifully displayed. I ordered on 16.08.2026 and received it in super good quality with a nice box and certificates plus a very pleasant self written note from the gemologist Raiha on 23.09.2026. I always knew where it was, as the nice team of Carateu kept me informed with updates. After the quality check the ring arrived in 2 days from Stockholm. Pricing, product, and overall experience considered, i couldnt have bought it anywhere for better value!

I recently bought a 10.13 ct emerald cut from Carateu, best decision i made. They are super reliable and the stone came as in the videos shown by the supplier. It matches the IGI certificate and it’s spectacular. Im very happy with my purchase and the support. A coloured diamond will be my next purchase for sure.

Outstanding customer service. The ring delivered is as expected: perfect. Thank you so much for a great experience.

I had an amazing experience with Carateu from start to finish. They were incredibly helpful throughout the entire process, and I'm really happy with how everything turned out.

I ordered their Candice ring with a custom orientation, and one of the things I particularly appreciated was the ability to choose my own diamond, it seems to be quite a rare option among European jewelers.

Raiha was absolutely wonderful to work with: always helpful, polite, and quick to respond. I was working with a fairly tight timeline, as I already had my engagement trip planned, but the team managed to produce the ring and get it shipped in time.

The ring itself is beautiful, just like I wanted, and the whole experience was smooth, personal, and reassuring. I’m very happy with my choice and would definitely recommend Carateu to anyone looking for a beautiful, thoughtfully made engagement ring and a great customer experience.

I placed an order with Carateu; I was a bit hesitant at first because there weren’t many reviews.
However, that quickly changed – Raiha looked after me.
She really gave me excellent support and helped me in every way she could.
It was a bit tricky because of my tight schedule, but I’m more than satisfied and would definitely recommend this retailer!
Brilliant – keep up the good work, Raiha!

They provided clear information of the process and have great customer support

The experience has been exceptional. Before shipping the diamond they have sent me a video of it so, i could confirm that it was the diamond i have ordered. They have shipped it earlier than expected. I am very happy with my purchase.
Would %100 shop again!

I had a great experience ordering my ring from this company. The ring arrived exactly as shown in the pictures, with excellent quality and beautiful packaging. The ordering process was smooth, shipping was fast, and the customer service was responsive and professional. I’m very happy with my purchase and would definitely recommend this company to others!

Amazing diamond! We were looking a very specific and hard to get diamond - champagne color approx 2ct. We found it only on Carateu. As the company didn’t have many reviews we were a bit stressed but all worked well! ♥️ communication was very smooth. We got a real video of diamond. Shipment was fast. After we received diamond our jeweler confirmed that everything was matching the offer and certificate. Diamond is beautiful! ♥️ thank you so much! And thank you for a letter we got from you with the diamond. It was really nice! 🤗 we recommend 100%!

It was amazing. It arrived very fast. It was the exact diamond that I ordered. Everything was perfect

The communication and service are impecable

Great Support, fast shipping.

Perfect ! My timing issue was really taking care of.

Everything was according to its description. I purchased a lab diamond, the price was very good, the quality of the diamond was amazing and the shipping went really smooth! Thank you Carateu for the very professional service. I will definitely buy again!

Perfect service
The representative of the company was really helpful with setting up a B2B account and leading us through the process. The diamonds that arrived to our place some time after that (within promised time period) were wonderful, better than in the pictures online.

I had an absolutely outstanding experience with CaratEU from start to finish.

I was searching for a very specific oval lab-grown diamond with excellent proportions, minimal bow-tie effect, strong light performance, and a clean, elegant appearance. Instead of simply trying to sell me the first available stone, their team carefully reviewed multiple diamonds for me and honestly advised against several options that did not meet their standards.

Their communication, transparency, and professionalism were exceptional throughout the entire process.

A special thank you to Raiha and the gemologist team in Stockholm, who personally compared several diamonds, provided additional videos in different lighting conditions, explained the differences between stones, and ultimately helped me find a truly stunning diamond.

The final diamond I purchased exceeded all expectations:

incredible brilliance and fire
almost no bow-tie effect
excellent cut and proportions
verified in Stockholm before shipment
exactly matched the IGI certificate

The packaging, handwritten note, insured FedEx shipping, and overall customer experience felt truly premium and personal.

What impressed me most was their honesty and attention to detail. At multiple points they recommended better stones instead of pushing a sale, which gave me complete confidence in the process.

I can wholeheartedly recommend CaratEU to anyone looking for a high-quality lab-grown diamond and a trustworthy, knowledgeable team that genuinely cares about helping customers find the right stone.

Thank you again from Croatia! 💎

I found Carateu through Reddit while i was searching for a diamond to make a ring. Raiha made the whole procedure as easy as it can be and i felt i was in the right hands from the start! I was a bit overwhellmed at first as i was not sure what to look exactly. They asked for all the details i was looking and presented me with their best product they could offer in my budget. That for me is a 10/10 customer service. They also provided me with more photos and videos when requested, which was greatly apreciated and the shipping was fast and w/o any problems. Prices are a big plus also as they seem to be as competitive as posible to EU region, All in all this was fast,easy and great experiance and i highly recomend to choose them for your next diamond purchase.

Fick jätte bra hjälp, svarade på mina frågor och val av diamant blev lättare tack vare carateu! Kommer köpa härifrån igen!

I ordered a diamond and it arrived exactly as described, in perfect condition and well packaged. Unfortunatelly I had to send the diamond back due to personal changes. However I would like to emphasize, that also the refund process worked out very smooth!

I definitly can recommend this shop. 10/10!
