Like finding treasure.

I love vintage style but shops are too costly. Found a sapphire pendant on GEMGEM, just like grandma’s. Got it for half price. Came safe, looks perfect. Meant for me.

Too good to be true?

I saw $3,200 ring for $1,850. Didn’t know the seller. But GEMGEM had checks, return, escrow. So I tried. Ring came and wow… so beautiful. Better than photos. I love it!

A Great and Secure Selling Experience

I had an old ring that I didn’t wear any longer and I selected GEMGEM to go and find it a new home. Their platform made it all feel safe and respectful. Communication was great and they were professional all the way through the transaction. “I am really pleased with the outcome and how simple they made it.

Efficient, Trustworthy, and So Easy!

I was trying to sell a set of designer earrings and I wanted it to be easy. GEMGEM was exactly that. Listing was fast and once I had a buyer their team took care of the payment and shipping details safely. The money was deposited in my account a little after the delivery. Very efficient and reliable service!

Great Support for a First-Time Seller!

This was my first time selling jewelry online, and I chose GEMGEM to list a silver locket. I was a bit nervous, but their support team was incredibly helpful, guiding me through creating an attractive listing and understanding the shipping procedure. A buyer was found relatively quickly, and GEMGEM facilitated the sale seamlessly. I received my payment without any hitches right after the locket was delivered. I'm very pleased with the support and the positive outcome!

GEMGEM's guidance during shipping was very helpful, and the security GEMGEM offered made me feel very safe throughout the transaction. Payment was made immediately upon delivery of the goods. Definitely, a reliable site for selling jewelry.

Will likely sell again

I listed a necklace and got a few messages from potential buyers. Eventually, someone made a good offer and GEMGEM helped handle the next steps. The payment arrived shortly after the package was received. It was a good experience overall, and I’d consider selling more pieces in the future.

Happy with the selling experience

Tried out the platform to sell a pendant I no longer wore. Uploading the item didn’t take much time, and I was contacted by a buyer within a few days. I was given clear instructions on packaging and tracking the shipment. Payment came through soon after the delivery was confirmed.

Helpful support and smooth delivery

Listed a ring for the first time and was a bit unsure how everything would work. The support team answered my questions and helped me prepare the item for shipment. The transaction was finalized without issues, and the buyer gave a positive response once they received it. Glad I gave this a try.

Clear communication and a quick sale

I recently listed a pair of earrings, and the process was really easy to follow. I appreciated how clearly everything was explained, from uploading the product to setting the price. Once a buyer showed interest, the GEMGEM team helped facilitate the rest. Payment came in not long after shipping, and the overall process felt very secure.

Authentic Labubus Giveaway Prize

I won their Labubu giveaway and they shipped it really fast! I was surprise that they gave me the entire box set with 6 blindboxes inside. I scanned the authenticity QR code and it is legit. I highly recommend this business as they honor what they say and shipped me my giveaway prize. I thought it was only going to be one single box but they gave me the entire set with 6 blindboxes and I am honestly grateful that they did that for me! 10/10 stars from me! Happy that I won this giveaway! Please support this business! 😊⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

Beautiful ring & excellent customer service

I won a gorgeous 3.6 Carat Blue Topaz Ring in 18 KT White Gold setting from this company's Facebook page. I sent the company a private message on Feb. 12. They replied back 7 hours later. I just received the ring on Feb. 26 via Fed Ex. I can't believe how fast I received it. The ring came in a beautiful pink lighted ring box. It contained all the important information regarding the ring. The ring is absolutely gorgeous and beyond my expectations! This is going to be my engagement ring. I definitely recommend this company to people looking to buy or sell quality fine jewelry.
