"Best Jeweler of the Southland"
Design your own ring
Show us a sketch, an inspiration photo, or simply browse our showroom to start the design process. You'll be wowed by all of the options. And yes, we gladly accommodate any budget.
Fashion Jewelry
Come by and see our unique pieces and popular styles. From our diverse inventory of rings, earrings, necklaces and watches you'll find the perfect gift.
Sell your unloved jewelry
Receive a complimentary appraisal on your gold and diamond pieces, including watches. All evaluations are conducted confidentially with honest, high-cash offers.
Watch restorations
We have over 20 years experience in polishing and restoring time pieces to their original luster. With careful buffing and polishing under slight abrasion, depending on the finish of your watch (brushed vs. high polish metal), we are able to remove the scratches and imperfections from daily wear.
Cleaning & Inspections
Ensure that your jewelry stays beautiful and secure by having it professionally cleaned and inspected by our in-store jewelry experts. Everyone can take advantage of our repair services, no matter where your jewelry was purchased.
“Blue diamond is truly the best. I came in for an engagement ring and left with a work of art.”
“I can't recommend Blue Diamond Jeweler enough. They are kind, professional, prices are fair (you don't have to worry about being upcharged here) and the service is always warm and welcoming.” ”
“They passionately explained everything to the smallest of details. You can really tell that they truly love what they do!”
“Never pushy and always patient. Their top priority was helping us get our perfect rings, rather than just trying to make a sale. ”
“We love stopping by to say hello because it's such a friendly setting. Definitely a "neighborhood gem".”
