I almost gave up trying to pick a tennis necklace because I had no idea how different they could all look until I started shopping. Every website had perfect pictures but I still couldnt tell what would actually look best in real life. I ended up calling Gem Jewelers Co and worked with Melissa and she made the whole thing so much easier. She actually picked out two necklaces she thought fit what I was looking for and sent me videos of both. We even did a FaceTime call where she showed me each one up close from different angles and answered every random question I had. It honestly felt like I was standing in a jewelry store instead of sitting at home in Texas while they were in LA. I finally decided on one and Im so glad I listened to her. The necklace is absolutely gorgeous. The sparkle is crazy and it lays perfectly on the neck. Pictures really dont do it justice. Ive worn it a few times already and people keep asking where I got it from. The best part of the whole experience was never feeling like I was buying online. Melissa made everything feel personal and took her time helping me choose instead of rushing me. Thats pretty hard to find these days. If youre on the fence or buying a tennis necklace for the first time just give them a call. Im really happy I found Gem Jewelers Co and I’ll definitely be back for my next piece. Thanks again Melissa for all your patience and help.

Diamond Tennis Necklace
My husband and I have had a great experience working with Joe on the selection of a diamond tennis necklace for our 40th anniversary. We selected a necklace which was very beautiful, but changed our minds on the style. Joe worked with us to ensure our complete satisfaction. Received my necklace today. We are very pleased with the experience and the results.

WOW WOW WOW im honestly blown away by…
WOW WOW WOW im honestly blown away by this necklace lol i knew it was gonna be nice but i wasnt expecting it to sparkle like this. The second my girlfriend put it on we both just kept staring at it 😂 it shines like crazy and catches the light from every angle. The best part is how good it looks with the diamond pendant she already had they just go so well together like they were made as a set. I was kinda worried the necklace would be too much or take away from the pendant but it actually makes the whole look even better. She hasnt taken it off since it came and i dont think she plans on it 😂 ive looked at so many tennis necklaces online and im really happy i went with Gem Jewelers Co. The quality is on another level and it just looks expensive the second you see it. If youre thinking about getting one just do it you wont regret it one bit.

Incredible jewlery and incredible service!
I was pressed to find a high quality tennis bracelet for my girlfriends birthday. I originally was uneasy ordering online and spending that kind of money, but Gem jewlers were extremely responsive! I noticed I filled out the incorrect address at the time of my order, and within hours they had updated the adress and assured me my package would arrive on time. 2 days later I got the package and safe to say, my girlfriend absolutely loves it!

An Exceptional Jewelry Purchasing Experience!
My recent purchase experience with Gem Jewelers is one of the best I have had. First, the jewelry is exquisite. The stones are high quality and the craftsmanship is excellent. The price point was the best I could find with online gemstone jewelry. You get exactly what you pay for, no hype, no dupe, the real deal.
The customer service is probably the best I have experienced. My initial necklace was so beautiful that I decided to increase the carat weight and get an exchange. Melissa handled the exchange and she is an expert. The response times to my inquiries were fast and thorough, clear instructions and pleasant communication. I could tell she cared that I as a customer had a great experience with Gem Jewelers. I will be a repeat customer for my jewelry needs because of the quality and care!

Thank you so much, Karyn, for your thoughtful review! We're truly grateful for your kind words and are thrilled to hear you love your necklace. It was our pleasure assisting with your exchange, and Melissa will be so happy to know she made the experience a great one. Thank you for trusting Gem Jewelers Co. with such an important purchase. We look forward to helping you again for many years to come! ✨

Flipping necklace, non-existent customer service
I made a very expensive online purchase here based on the Trustpilot reviews so it's important to relay my recent experience. 5 weeks ago I ordered an adjustable tennis necklace and was assured it would NOT flip despite its adjustable nature. It arrived and immediately flipped no matter which direction I put it on. I called in a panic and was told there was no one who could speak with me about the issue, that I needed to SCHEDULE a phone call. I emailed videos of the defective item while waiting. 4 days later/1 hour before the first available scheduled call, they asked me to cancel the call and send the necklace back so they could see it in person. They also said they would need to make it a fixed length as the clasp on the adjustable portion of the necklace was likely causing it to flip. I shipped it back that day, June 23, and I was told on June 24th that they would provide me with an update when it arrived. It arrived June 26th- no update. On July 1st I emailed and got a response that they would provide an update on July 2. No update. On July 7th I again emailed asking for an update and they blamed the holiday weekend and promised an update by end of day. No update. I emailed yet again today July 13th and have not received a response. So I paid for an expensive necklace 5 weeks ago that was not as advertised, that I no longer possess, and the customer service to address this has been non-existent. They are also advertising free diamond studs with all orders $1500+ and when I asked about that in one email I was ignored.

Hi Jennifer,
Thank you for taking the time to share this, and we sincerely apologize for the experience you've had. This is not the level of service or quality we aim to deliver, and we want to make it right.
After checking your account, it seems our team worked with you on a custom adjustable bezel necklace. Adjustable designs are more complex to construct than our standard fixed length pieces, since the setting has to hold its shape correctly no matter how the length is adjusted.
We wanted to accommodate your custom request as you envisioned it. Once you reported that the necklace was flipping and not laying correctly, we took responsibility right away.
Rather than attempt a partial fix, we agreed to fully exchange and remake the piece as a non-adjustable 15 inch necklace with a secure lock closure, a sturdier and more stable setting overall, at no additional cost to you. We wanted the final piece to be something you'd be genuinely happy wearing, not a patched version of the original issue.
We hold every piece to a standard where it needs to be right before it goes out the door, and a custom rebuild like this takes time to do properly, so it took slightly longer than expected.
We also want to acknowledge that our communication during this process fell short. Between the July 4th holiday and the usual summer season, our team was stretched thinner than normal, which affected how quickly we could keep you updated. We're sorry for that gap, and we're taking steps to do better.
I can see here that a team member reached out to you again this morning. We are here if you need anything further, please feel free to reach out any time. Sorry again, and we look forward to helping you again in the near future.
Best,
Christine
