Excellent quality of gems and service!

I had a great experience here, and I'm very happy with my order. Sam and his team communicated well and politely with me, and I will definitely order from here again!

I placed my order on 7th April and received it (in Europe, with unpaid import tax) on 25th April. I had a brief email exchange with Sam on 10th April when he informed me that the Pulled Czochralski Ruby i ordered was not available in current stock in a baguette cut, but they had one in emerald cut if I would like that instead. This was totally fine for my purposes (i also assumed that the order would take longer if they had to create and cut the ruby, but i never asked this).

The gemstones arrived carefully packed and undamaged. The quality of the rubies and moissanites was excellent, and I'm very happy with them! I also ordered hydrothermal rubies just as a comparison with the pulled rubies and I think for the purpose of turning them into jewellery there is no difference in quality to the naked eye. The moissanites (5mmx5mm square cut) came with GRA certificates+warranty cards, and were excellent quality overall.

I would highly recommend this store to anyone interested in gems!

I love the quality gem stones…

I love the quality gem stones purchased. The ordering process is straight forward and the selection is outstanding. The only issue I encountered was a delay in delivery and this is related to the Country the product is being ordered from and not the business itself. I made an inquiry about the purchase and Sam was great in communicating the status of the order and provided tracking for me. Shipping international can have its challenges, but the wait was well worth it. Beautiful quality stones that I cannot wait to use in my jewelry. I am looking forward to making another purchase soon. I appreciate your prompt response to my email inquiry and love the quality products you offer. Please continue to offer such beautiful stones, with a wide selection of sizes to select from.

I bought an aquamarine stone

I bought an aquamarine stone, it arrived in less than 10 days to Australia. It’s hard to get loose stones in Australia, to make a custom made ring. The stone I ordered was beautiful and even the jeweller commented that it is high quality.

Superb products, selection, quality & service

I was thrilled to find Gemsngems because their selection of lab-created stones is excellent, including some that are particularly hard to find, even unique. As a jeweler this doesn't happen to me very often, but I was genuinely excited to place my first order because so many of their products looked amazing and were so far behind. Best of all, the quality and beauty of the stones I received actually exceeded my expectations. I've placed several orders since then, and they've always been quick and very helpful to accommodate any questions or requests I've had. Overall, Gemsngems (sorry for the pun) is a true gem, and so happy I found them. Thanks so much again for all your help and beautiful products!

My first gemstone order ever

It was my first time order of this nature.
My order was over $4000 U.S.
I was uncertain and had questions.
Sam was patient and helpful.
There was a shortage of 2 items I ordered but we were able to find replacement choices.

Order arrived with no issues.
The stones are quite impressive!

I will order again.

Amazing quality, great service

Good customer service and product

I decided to buy some lab gems, a alexandrite and a tourmaline and they are really pretty. I choose the cheapest delivery and it took about 3 weeks, after some while I hadn't received the tracking information and decided to send an email. Sam replied really quick and was helpful, I got send updates about customs and pick up at te post office. So the customer service is really good. I would definitely buy again.

Trust is Everything

I have been buying the lab made items for many years and have always found Sam to be easy and old fashioned in business. With living in Thailand I pay by bank transfer and then I get the stones. It's that easy.
With the latest order, the wrong stone was sent so I returned it, sent the tracking and the correct one was received a few days later.
I recommend his work.

Great company to work with.

My order took a little longer than expected, but not much! I ordered in bulk for my business. Great prices, great quality, consistency and color. I recommend their gems and customer service!

Beautiful gems. Arrived damaged, but Sam made it right.

I ordered 3 very large, custom cut Moissanite stones from Gemsngems. The gems arrived damaged with chips in them. They were all packed together directly touching each other. I contacted Sam and sent him closeup photos. He rectified this situation by remaking the gems, they arrived in perfect condition, all very well packaged in individual padded containers. How a seller corrects an issue says a lot about them; I would buy from Gemsngems again.

Good as hoped better than anticipated!!

My name is Gary from the USA I ordered lab grown emeralds and diamonds from Gemsngems. The stones received were as good as hoped for and better than anticipated. They stayed in touch with us through the process. I will definitely use Gemsngems again when I buy stones.

Synthetic emerald

I bought a 5x5 mm synthetic emerald labeled as ”flux grown”. Shipping was fast and communications excellent. The product was not exactly as described - It’s a synthetic emerald showing clear signs of being produced by the hydrothermal method, not flux grown.

Reply from Gemsngems


Thank you for your feedback and for taking the time to share your experience. I'm very glad to hear that you were happy with the fast shipping and communication.

I'm sorry to hear that you believe the emerald you received was not flux-grown. I can assure you that the stone we sent was indeed a flux-grown synthetic emerald, as described in the listing. We work closely with trusted suppliers and ensure that the materials are correctly identified before being offered for sale.

Could you kindly share how you determined the emerald was hydrothermal rather than flux-grown? Was it tested by a gemologist or lab? We'd truly appreciate any additional information, as we take concerns like this very seriously and always want to ensure transparency and accuracy in our listings.

Please feel free to reach out directly if you’d like to discuss this further — we’re here to help and make sure you’re completely satisfied with your purchase.

Best regards,
Sam

Authentic, Affordable, Easy, Beautiful

Excellent experience. Affordable, even after the conversion from their listed USD prices. Sam at gemsngems.com had great communication and informed me of useful options and got the gems in my hands so fast.

Authentic gems (rubies, emerald, peridot) from them are so wonderful to have. I did 4 tests and they passed them all: Electric Conductivity, Hardness, Scratch, and UV. Knowing these guys are the real deal is comforting.

I'm excited to buy more. I highly recommend them.
