Extremely happy with our purchase

I’m extremely happy with our purchase of the graduated Diamond tennis necklace from Gem Jewelers Co. I took a leap of faith after finding them online and as I have read from other people, their quality definitely stands out from other competitors that I have seen and definitely amazing prices. We got the necklace in the mail a few weeks and are extremely happy with the way it looks and the quality. We also appreciate their amazing payment plan which helped us greatly in purchasing this gorgeous tennis necklace. I highly recommend Gem Jewelers for anyone looking for a very high-quality tennis necklace. Thank you!

Miracles are possible when you have the right partners!

Joe was an amazing partner to not only design but deliver a breathtaking custom piece that will be a show piece tennis bracelet in our family for generations. He helped me with assessing the right quality GIA certified stones for my anniversary gift to my wife. The team worked to all hours of the night. Despite it being during busy holidays Joe and the team were able to work a miracle and deliver from start of design to in an overnight FedEx within 3 business days. Joe didn’t stop there, he followed up continuously to make sure the delivery made it to me. He made it possible for me to have it just in time to surprise my wife on our anniversary.

18 in 5 carat TW diamond/platinum tennis necklace

I ordered an 18-inch, 5 carat total weight, natural diamond tennis necklace from Gem Jewelers as a gift to my wife for our 30th wedding anniversary. Their website was easy to navigate, their customer service was top-notch (especially Jessica who helped me throughout), and the item arrived as-advertised and on-time (a week before our anniversary)Gem Jewelers offered a better selection of platinum necklace lengths (14 to 18 in vs. only 16 in elsewhere) and total diamond carat weight (3 to 15 carats) than available elsewhere, and they offered a better average diamond color (G vs. H-I elsewhere) and clarity (VS2 vs. SI1-SI2 elsewhere) for less money.Gem Jewelers also offered a 10% Labor Day discount and even suggested I order the necklace a day early to avoid impending price increases due to tariffs (I checked later, and prices did, in fact, rise the day after my purchase). They also gave me a $100 new customer discount.To top it all off, they included a free pair of 1 carat total weight diamond stud earrings.My only (very slight) negative feedback: For some reason, their platinum diamond tennis necklaces are final sale (not eligible for their 14-day, no-questions-asked, money-back guarantee available with their white, yellow, and rose gold necklaces) so I had less room for error! Fortunately, I got it right, and my wife loved it!If the platinum necklace hadn't been final sale, I might have exchanged it (and spent a bit more) for the 7 carat total weight option for some added sparkleOverall, a great experience. No regrets! I recommend Gem Jewelers and will definitely shop here again!

Thank you

I bought a diamond tennis necklace from Gemjewelers co. I was not very knowledgeable about diamonds. Christine spent more than an hour to explain to me how to determine the quality of a diamond. She also showed me the different options I had as far as diamond tennis necklaces were concerned. She never pushed me to buy anything, she was just there to help out. I eventually picked up a gorgeous necklace. I was delighted to put it on. The price was very affordable. I got a good discount. Thank you, Christine! You are the best!

I’ll be honest—at first

I’ll be honest—at first, I was skeptical about ordering fine jewelry online. When I bought my first tennis necklace from Gem Jewelers Co., I actually took it to a local jeweler to verify everything because I wanted to be sure it was the real deal. Not only did it check out, but the quality was even better than I expected. Since then, I’ve become a loyal customer and honestly wouldn’t shop anywhere else.My collection now includes 2 tennis necklaces ( One Graduated one classic of course lol ) and a beautiful tennis bracelet from them, and I’ve been impressed every single time. The necklaces have this amazing non-flipping design that lays perfectly on the neck, which is so hard to find. The bracelet is classic and elegant—exactly what I was looking for. Every piece sparkles like crazy and feels substantial, not lightweight or flimsy like some others I’ve seen.What really sets Gem Jewelers Co. apart is the combination of unbeatable prices and genuinely great service. They always respond quickly, answer questions with patience, and you can tell they care about making sure you’re happy with your purchase. It never feels like a sales pitch—it feels like you're dealing with people who truly stand behind their product.We’ve been shopping with them for a while now, and I can confidently say they’re the best in the business when it comes to quality, price, and customer experience. If you’re on the fence like I was, just go for it. I’ve never looked back.OH BTW Ask for Joe for the extra special treatment.

I highly recommend Gem Jewelers

I highly recommend Gem Jewelers! I was looking for a specific piece and asked if they had anything like it—they offered to custom-make it for me on the spot. The whole process took just a few minutes, and the final piece turned out even better than I expected. It was ready in just a week and came at a great price!

Diamond tennis necklace!!

I’d been wanting a diamond tennis necklace for a while but didn’t know who to trust. A friend told me to check out Gem Jewelers Co., so I reached out — ended up speaking with Joe, and he was honestly amazing.He didn’t try to upsell me or push anything. Just really helpful and patient. He walked me through all the different options, explained the differences in diamond quality, carat sizes, and even little details like how their necklaces are made to not flip (which was something I didn’t even realize mattered — but now I totally get it).The necklace I got is beautiful. The diamonds are super bright, it sits perfectly, and the whole piece just feels really high-end. I’ve worn it a few times already — to dinner, an event — and people always compliment it. One person even asked where I had it custom made.And price-wise, I was honestly shocked — in a good way. It’s a natural diamond, not lab-grown, and the quality was better than some of the stuff I saw in stores around LA that were literally twice the price.If you’re looking for something timeless and high-quality without spending retail store prices, definitely hit up Joe at Gem Jewelers Co. I had a great experience, and I’m already thinking about getting a matching bracelet next.
