"Amazing selection and service!"

Great selection of diamonds and amazing price.
Customer service is one of the best I have encountered. Viktoria and Nikolay managed to deliver the diamond I purchased a week earlier than expected (and on a Sunday).
Very happy with the purchase and service!

"Oh I absolutely love my ring"

Oh I absolutely love my ring. Received lots of compliments. The website was pretty easy to use. I had a custom ring made and I must commend the process as it was incredibly seamless. Took all the corrections I wanted and made adjustments in record time. Would 100% recommend!!

"A Truly Ethical Choice…"

A Truly Ethical Choice with Outstanding Customer Service.

I recently purchased a lab-grown diamond from Moon Ocean, and I couldn't be happier with my decision. As someone deeply concerned about the unethical practices of the traditional diamond industry—especially companies like De Beers, which have a history of monopolising the market, inflating prices, and offering sub-par products—I knew I had to choose a more ethical and sustainable option. Moon Ocean surpassed all my expectations.

From start to finish, their customer service was impeccable. Viktoria, the head of customer services, deserves special mention as a fantastic ambassador for the company. She guided me through the process with professionalism, warmth, and prompt communication. Even when I encountered an issue with payment, their live chat support resolved it quickly and kept me informed every step of the way. This level of care and transparency is rare, and I generally have very high expectations for customer service.

The packaging was beautifully presented and included a certificate of authenticity that can be independently verified. The certificate matches a microscopic laser-etched serial number engraved on the diamond's edge—a detail you can't see with the naked eye but that proves its authenticity.

Choosing a lab-grown diamond felt like the right decision for me, both ethically and in terms of quality. Moon Ocean delivers a product that is flawless and guilt-free, making the traditional diamond industry feel archaic by comparison.

I cannot recommend Moon Ocean highly enough. If you're looking for a sustainable, ethical, and high-quality alternative to mined diamonds, look no further.

"Moon Ocean are great!"

Moon Ocean are great!

I bought a loose marquise diamond from them for the most reasonable price compared to other retailers selling the same diamond.

I dealt with Viktoria whose communication was awesome and provided a first class service which gave me real confidence in buying through them.

I would highly recommend!

"I wanted a ring from their high…"

I wanted a ring from their high jewelery category, but the price was too much. But, Camilla from online support explained me that they can do it with lab diamonds instead of naturals. In 5 weeks i got my replica with labs. I am super happy - my cocktail diamond ring looks amazing.

"I was a bit hesitant at first"

I was a bit hesitant at first. They are a relatively new brand, and buying an engagement ring is no small decision. But the aftertaste is the following: 1) great service experience 2) Perfect looking ring delivered on time. 3) price for my ring + lab diamond was better than other brands I looked into.

"Many thx to Andrew for his patience"

Me and my partner ordered custom wedding ring. Andrew, the ring designer, remodelled the ring 3 times for me - since i wanted to add some details and additional sidestones at a later stage:) Eventually i was happy and gave it a "Go" for Production. Frankly speaking, i though they would charge us extra for the headache, but Andrew took it like a Champ! At no additional fees. My ring looks stunning. Thank You Moon Ocean!

"Loose diamond purchase"

I recently purchased a loose lab diamond from them. Online service was very helpful - got all details about the diamond and its qualities. Price was very good.
