My fiance bought me a beautiful Garnet engagement ring about a year ago through their Amazon store. Last week one of the side stones fell out. I contacted Gem Stone King and, since it was under their lifetime warranty, they replaced the ring at no charge! The process was quick and painless! I'll definitely be shopping with them from now on.
Purchased a tanzanite and diamond ring online. The ring is AMAZING! I've also purchased a tanzanite bracelet that I love and a diamond heart necklace. All jewelry comes with a lifetime warranty that this company stands by. My 5 year old white gold charm for my necklace tarnished a little bit. I sent it to them and they sent it back looking brand new. I will purchase ALL jewelry from this store going forward.
My significant other bought me a beautiful ring for Christmas, but the wrong size. We sent it back before the New Year for a different size all via email, and they had the new size sent back within a week. I love my ring! It is beautiful, well made, and really just stunning! I wear it constantly and have had no issues. Thank you for such a beautiful piece of jewelry!
Color on amethyst heart earrings are pale and nothing like the pictures. Ear wires are also not the same as the pictures. Really not the quality that I expected. Probably won’t order anything else from them.
real gold but the emerald was glass don’t buy from these guys
So let me start off with how I came across Gem Stone King. Last year I ordered a customized tennis bracelet with gemstones for my mother for a Christmas present. The company I ordered hers from was by Ross Simons, which was very similar to the tennis bracelet with gemstones I received today, for my birthday. Let me just say that I’m very impressed not only by the gemstones that vibrantly shine, but also the craftsmanship, which is absolutely stunning. Thank you Gem Stone King, I’m very pleased with my birthday present, and will DEFINITELY recommend to family/ friends!!!
First purchase from Gem Stone King...Received my pendant which was exactly as shown on web-site. I am in my late 80's and I was thrilled to see the remarkable workmanship - including the engraving. Thank you for the prompt delivery too.
I frequently purchase from this company on Amazon and am pleased with my purchases 99.99% of the time. I appreciate the fast shipping; I love not having to wait weeks for my lab-grown diamonds. The return process is also easy, with no questions asked if you’re not satisfied, which I really like. However, I believe there are three areas for improvement. First, the band could be a bit heavier. It feels very lightweight and paper-thin, which makes it seem too delicate and fragile. Second, when you buy a lab-grown diamond, whether small or large, I would like it to come with a IGI certificate and stone ID # too. Lastly, the engagement ring heads sit too high. This is particularly noticeable with a 3 or 4-carat stone, making it look oversized and fake. A low-profile, seamless setting would be much more elegant. It wouldn’t catch on everything, and you wouldn’t have to worry about chipping, cracking, or damaging the ring in any way. A low-profile setting is stunning, especially for larger stones, anywhere from 2 to 4 carats. I hope they make these changes, as a halo setting should look seamless. The gap created by having the stone sit so high is just not appealing; an elegant and safer design is definitely preferable.
There was a little hiccup with shipping but the company ensured that they corrected this, and eventually sent the package by expedited FedEx mail. Great customer service and the silver necklace was exactly as pictured. Very pleased with both the service and the product.
2 years ago I bought an 18k rose gold plated heart necklace which has since turned black (I discovered this when I went to wear it for my anniversary). I clean my jewelry after every wearing and keep it stored in an air tight container. Real rose gold doesn't contain any kind of metal that tarnishes. This company fraudulently misrepresents the quality of its jewelry.
Dear customer, Thank you for sharing your feedback. We’re sorry to hear about your experience and understand how disappointing this must have been. The necklace you purchased was 18k rose gold plated, which means it has a rose gold layer over another metal, most likely silver. Unlike solid gold, plated jewelry can naturally tarnish over time, even with careful care. We strive to provide clear product descriptions and regret any misunderstanding. Please feel free to reach out to our customer service team—we’d be happy to assist further. Thank you for your feedback as we work to improve. Warm regards, Gem Stone King
As I indicated to a Gem Stone King representative, it’s refreshing and nice to deal with a reputable company, and in my opinion, Gem Stone King is definitely one. Recently I purchased two semi precious stones for some custom earrings, but although they were exactly as advertised and beautiful, I decided that they didn’t match some other already worn jewelry by my girlfriend and returned them. Gem Stone King accepted the return without issue and refunded my purchase price less a very reasonable restocking/shipping fee. Undoubtedly Gem Stone King is a reputable company and I highly recommend them as a source for your jewelry product needs.
Love it. That was awesome
Items looked like their website and I received my order quickly.
This company is fraudulent. Thank god I have some gemology training. No treatments were declared for the necklace we bought. Under the microscope it was clear that the sapphire had been heated and is heavily fractured, the "ruby" is that lead glass filled junk and still looks heavily fractured with poor clarity. Facet junctions on the gems look like someone has owned these stones for 30 years, they are heavily chipped. Will be contacting for full refund. Buyer BEWARE. This is illegal behavior and completely unethical.
Very good communication on my order and the ring is just gorgeous! I also liked getting the additional $10 off my purchase!
I bought a necklace with my birthstone as pendant. I love it, it looks nice.
I like the design of the sapphire earrings, they are so match my sapphire ring
I am beyond pleased with the items I ordered. The design in both rings is so delicate and out of the ordinary. You have gained yourselves a new loyal customer! Have a wonderful Christmas and New Year's season.
