I've had nothing but positive experiences with Moissanite Co. My husband and I bought our wedding rings here. I loved it so much that I came back to buy the birthstones for my two daughters. Purchasing process was super easy and I love that they include videos and photos of their products so that I see exactly what I am buying. Shipment was quick and I received my orders I. A few business days. I would highly recommend them and will definitely return.
I spent $2,489 on a custom ring from MoissaniteCo, expecting a high-quality piece based on their marketing and warranty. Unfortunately, what I received was not up to par. The Moissanite center stone had a very noticeable bowtie effect and poor light performance. The engraved setting looked unfinished, with blurry detailing and visible burs—even to the naked eye. After raising these concerns, I returned the ring, but they withheld $497.80 from my refund, calling it a "custom cancellation fee." This made no sense to me, especially since their own warranty promises jewelry will be free of visible defects. I also had a professional jeweler confirm the flaws before returning the ring. They refused to acknowledge the issues and dismissed the jeweler's input as biased, despite never offering their own formal assessment. I've filed complaints with the BBB and FTC, and initiated a dispute with my bank. I really wanted to support a smaller jeweler, but this experience left me frustrated, out nearly $500, and without a ring. Think twice before committing to a custom piece here, especially if you're relying on their return or warranty policy for protection.
I haven't made an order quite like one with MoissaniteCo before, and I'm hoping I don't have to order any other engagement rings again 🤣 but the ring shipped a day or two before its projected completion date, based off their processing times, and I was very surprised at the level of detail put into the little markings and designs below the stone's bezel, and I have no doubt it's genuine 18K gold, as my fiancée has already worried herself sick about having put the tiniest scratch on the bottom of it. It's to be expected with higher purity gold though, it's a soft metal! The stone sparkles in a way diamonds could only hope to achieve, and the ring itself is a gorgeous glimmering gold. I was surprised to be able to get such a beautiful ring at such an affordable price, but that's the benefit of moissanite, and why I came here! Thank you for exceeding my expectations!
I asked many questions and even made changes to my order after it was placed. I had a great experience with all of my questions being answered in a timely manner and an easy process to changing the order after it was placed.
The process of your costume ring is so easy and fast response. The ring is STUNNING that I'm speechless on its beauty. The sparkle on my custom size Radiant cut is outstanding with all that sparkle. My ring just sparkles like crazy with the lab side stones and the hidden halo.
Great company and great products. It's was great experience dealing with you all. I would definitely recommend this company to anyone that's looking for quality jewelry. Keep up the great work. Thanks agin for a job well done.
Mossinate Co staff worked with me to create a custom aquamarine pendant. Way nicer, bigger gemstone than competitors at the same price point.
My partner loves her birthstone necklace!
They did fix my ring the second time I sent it in. I only wish that they would have contacted me instead of me having to send it back again. Some stones were not right and I was willing to pay to have them replaced. But had to pay to send them back to replace the stone when if ask I would have told them to go ahead. But great job they did so you don't need to worry about anything!
I was very impressed by thier at home trial rings and decided to use them for a wedding band. They did an awesome job and worked to make me happy! Very awesome company. Can't wait to order again and geta variety of bands to change out the look of my engagement ring!
Great Service! All good! Everything was fantastic.
Moissante Co is so easy to deal with. Always extremely satisfied. My ring is beautiful. Thank You.
Beautiful product and she absolutely loved it! Most affordable option!
Yes, I received it and love it! So happy with all my pieces from Moissanite Co. I'll never buy real diamonds b/c there is no reason when you have a quality product like these! Thank you!
Wanted to return an item within the 30 day window. After much back and forth they says no, item needed a security tag. No tag was on the item initially, it was on the main ring. They offered to resize, but the band didn't support the ring with a large stone. When I originally inquired to purchase an additional band, I was quoted almost $200 more than I was charged for the first band.
The engagement ring is beautiful, the band is cheap and thin. Company is not easy to work with, go to a local jeweler and save yourself the headache. There's not much difference in cost.
Moissanite Co provided the perfect ring for my best friend's wedding. The moissanite's brilliance was stunning, and the customer service was excellent. The ring exceeded our expectations and made the day unforgettable. Totally worth it!
Moissanite Co exceeded my expectations with its stunning collection and exceptional customer service. From browsing to purchasing, the experience was seamless and enjoyable. Their knowledgeable staff guided me through the selection process, ensuring I found the perfect piece. The quality of their moissanite stones is remarkable, and I couldn't be happier with my purchase. Highly recommend!
Answer: We are located in the USA. It would be made and shipped from the USA.
Answer: No telephone number, you have to send an email and it could take 24 hours to receive a response
Answer: Scam - they sell inferior products, their craftsmanship is of low quality. After you have made a purchase, you are left with no recourse if the item is not up to par, not as advertised, poor quality. The owner is rude and has no idea how to retain clients

We are sorry that in the end he wasn't pleased with his purchase. However we’d like to clarify a few of the details.
The custom ring was returned and thoroughly inspected by multiple GIA-trained gemologists employed by our company. All of them independently concluded that the Moissanite stone did not have a bowtie effect or any light leakage. This was a professional, fact-based evaluation—not an opinion. Below is a link to a picture of the ring and Moissanite for this order.

The ring itself showed a high-quality finish, including clean engraving and polish. We do concede that small imperfections can be seen under magnification, but this is true of all hand made jewelry.
The customer referenced an unnamed third-party jeweler (a competitor) who noted defects. However, when asked to provide a written evaluation or any supporting documentation, none was provided. Without verification, we can only consider it an informal and potentially biased opinion.
While custom orders are typically non-refundable, we made an exception in this case. We accepted the return and refunded 80% of the purchase price, withholding only the standard 20% custom order cancellation fee. This policy is part of the terms of sale agreed upon during the ordering process.
This appears to be a case where the final product did not meet the customer’s expectations—not one where the ring was defective. Nonetheless, we extended flexibility beyond our normal policy. We remain committed to transparency and stand by the quality of the ring that was delivered. And in the end, we are sorry that the ring didn't meet the customer's hopes and expectations, despite being a beautiful ring.
Update: We respectfully disagree with the claim that we don’t stand behind the quality of our jewelry. From the very first communication, we offered support and were responsive to Fabian’s concerns. Despite the ring being a custom piece made to his exact specifications—which is typically non-returnable—we agreed to buy it back and issue a partial refund. That flexibility reflects our commitment to customer satisfaction and product integrity.
We also tried to explored multiple solutions, including offering to replace the Moissanite with a lab-grown diamond. Unfortunately, all attempts to resolve the matter were declined.
