Moon Ocean Reviews 

Stone arrived before expected. Great comms throughout & we're thrilled with it in person.

My bespoke ring is absolutely stunning. The whole experience was seamless, with tailored advice I got a diamond that completely exceeded my expectations. Having bought from luxury stores before, I can honestly say this is on another level. Thank you Anton and the Moon Ocean!

Highly recommend Moon Ocean. The pricing is unbeatable and the quality of the design and craftsmanship is superb. Huge thanks to Anthony and Viktoria for their wonderful customer service!

I ordered a loose lab grown diamond recently from Moon Ocean with no problems. I mostly dealt with a lady named Viktoria who was very knowledgeable and helpful. I needed the diamond by a certain date and it was delivered as promised. I'm very happy with my purchase and wouldn't hesitate to use this company again.

A beautiful diamond ring and excellent customer service from Viktoria. Nothing was too much trouble for her sourcing my perfect stone and the setting is breathtaking. I honestly couldn’t be happier with the end result. Far exceeded expectations and I am fussy. Thank you so very much. I would highly recommend Moon Ocean. The whole process takes time but is definitely worth it. I am over the moon. 🩷💍

tried to get a diamond on a coupe of occasions, was asking the normal questions and get info then they just stopped replying. Terrible customer service I would not recommend.

They only have a mobile number and it rings to someone who i think is outside of the country... i would be very very sus of ordering from them

I placed an order with this company over a month ago. I hadn't heard anything about my order for over three weeks, so I decided to message the company to see if there was a problem with the order. After I received no answer from them, I called them on their phone number... which is a mobile number, no landline seems sketchy to me, but anyway, there was no answer. When I eventually got hold of them, the person who answered the phone coincidentally told me that they were just now in the middle of sending me an email to explain that the diamond I had selected had a flaw. They were going to send me suggestions for a replacement. After selecting a replacement, I still haven't received anything from them. I have sent them emails and tried to contact them by phone since, but I have had no reply or answer to my attempts at contact. this company may have good prices on their website but what good is a low price when you never receive the product... either this company is a scam or they have the worst customer service known to man with highly incompetent staff who are seemingly unable to answer a phone call reply to an email or do anything at all related to their so called job. will never use this company again if they are are a genuine business they are an awful one and deserve to be shut down but in all likely hood i wouldn't be surprised if its a complete scam. if you're considering ordering from here... DON'T!

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. 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 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!

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 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. 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.

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!

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.
