Let's talk about integrity. Blue Marlin Jewelry was recommended as a reliable place to repair two bracelets that were extremely important to me - and they vastly exceeded my expectations. I am so impressed with their knowledge and experience - aside from advising me on the best way to implement the repair, they actually took the time to explain the process, and options, to improve the durability and appearance of my jewelry.

I'm floored by their attention to detail and extraordinary craftsmanship. They won a customer for life with their kindness and commanding knowledge of making, repairing, and purveying premium and iconic jewelry. By the way, their collection of nautical creations is extraordinary. A must see.

We stopped in to Blue Marlin as mere tourists just killing time. We received the kindest attention from Penny. She patiently guided us through their exquisite selections while we floundered (no pun intended) to make a decision. We left thrilled and excited at finding our future wedding bands. Our deepest thanks as we know what we purchased will shine brilliantly in our hearts.

25 years ago I purchased a ring from Blue Marlin Jewelry. An opal cracked this year. I called and was thrilled that Armando was still at the store. Penny was a huge help with setting up the repair of my ring. A beautiful experience, once again.

I've been married for 46 years, and lost the diamond from my engagement ring. This jewelry store not only replaced it, but made rhe experience very special! I highly recommend this store!

I haven't received my item yet but Blue Marlin was engaged from the moment I ordered. I have a quick story.many years ago I managed a high volume tourist restaurant and during a particularly rough time in my life in addition to a chaotic day, I discovered a little Blue Marlin gift bag, with a card addressed "for you", although it was not specifically for me the card was a kind and thoughtful expression to whomever discovered this bag with a shiny jewelry bobble in there.

I hope that many more of your gifts found there way to the right person's at just the right time! Your a stellar part of our community and from me personally. I'm grateful you are part of our keys community, you are wonderful owners, managers, and staff!

From the minute you walk through the door, it speaks of class and world-class service. The selection is vast! Penny, Shannon, Corrine and the new associate were very welcoming and pleasant. I had the opportunity to meet Armando, the owner who was quite gracious and appreciative of the business. I left some watches for battery replacements and the receipt shows photos of your item left for repair, which impressed me. Who customizes classy receipts? They also displayed some unique phone holders with fish, turtles, flamingos, etc. and lots of bling! Check it out! You will not be disappointed.

They are the best! I Was having my rings cleaned and Armando noticed the prongs were loose on my diamond. And my wedding band had a crack in it. I got both back. They look brand new after 41 years! The staff at Blue Marlin are so helpful and knowledgeable. Thank you so much Blue Marlin!
