An Experience as True as You

Kaeleigh Testwuide | Founder & Diamond Expert

After growing her professional career as a diamond expert with other brokerage firms and jewelers, Kaeleigh was determined to change the way that real people shopped for diamonds. Not only was she inspired to break from the traditional, male dominated industry, but she saw an opportunity to have a greater impact by bringing a private diamond buying experience to Denver. 

In 2015, she rebranded The Diamond Reserve into a female led, custom fine jeweler with a foundation built from integrity. 

Fast forward nine years, 3,000 happy clients and endless proclamations of “I do!”, Kaeleigh and her team have transformed bespoke jewelry in Colorado, Texas and beyond. 

When Kaeleigh is not raising her wild-spirited son, Cal, in the Rockies, you can find her right where she belongs; in the Cherry Creek North office hand selecting each and every diamond to ensure that The Diamond Reserve showcases the finest selection of loose GIA certified diamonds. 

As the brand continues to expand, Kaeleigh has made a promise to never stray from The Diamond Reserve’s mission: to provide unparalleled diamond education and one-on-one customer service to see that every client is investing in a forever piece that is a true representation of their love, budget and deepest desires.

I cannot recommend The Diamond Reserve enough! We loved working with Kaeleigh. She made picking out wedding bands an exciting and easy experience. Not only that, but she helped my fiancé guess my ring size perfectly based on looking at a photo - amazing!! The Diamond Reserve has a fun and comfortable atmosphere too, making it that much easier to find the perfect rings. We couldn't be happier with the whole experience and adore the rings we picked.

Erin Kurtz | Diamond and Jewelry Design Expert

Erin has been a driving force behind The Diamond Reserve since the beginning.

In 2016 she was on-boarded as an Executive Administrator to work alongside Kaeleigh. Six years later she has successfully implemented unparalleled customer service, an authentic client experience and progressive business strategies that have been incremental to the brand’s competitive edge.

You see, diamonds and Erin have always been better together. Yet, it took adopting the brand’s process (and her own design style) for her to realize it. As a laid-back, intentional woman, Erin always thought diamonds were meant for the elite. Until she started approaching her client relationships with a new perspective. By crafting custom pieces with real couples, she has found that diamonds were always meant for anyone who had a story for one. Including herself.

Today you can find her in her element at the Austin office as she warmly greets everyone who walks through the door and creates timeless pieces that perfectly embody the divine human connection we share.

When she is not setting high standards in the office, you can find her pedaling around the city or in her garden with her hands dirty (yes, there is a diamond for that too!).

We visited two other jewelry stores before meeting Erin at Diamond Reserve. Erin took the time to explain all we needed to know about picking and purchasing an engagement ring. She is so patient, helpful and willing to answer all my questions. She has gone above and beyond and created a beautiful engagement ring. I also went back to Erin to help create a necklace for my mom, which she loves! Would highly recommend Erin and The Diamond Reserve!
