Hello!

I’m Kaeleigh Testwuide, the Founder and Diamond Expert at The Diamond Reserve. Thank you so much for being here with us as you celebrate your next new beginning. 

As you start this journey you will find that our team’s top priority is to educate you on the do’s and don’ts of buying a diamond to ensure that you are getting the best diamond at the best value.

Historically, the industry has been clouded with a lack of trust and misinformation when it comes to purchasing a diamond. However, we are here to show you that an honest and personal diamond buying experience is attainable.  

The Diamond Reserve does diamonds our own way. The right way. My team stands behind our process, values education above all else and always stays rooted in the true meaning behind your investment. 

Are you thinking about popping THE question, upgrading your diamond, redesigning your setting, or looking for a special gift? Send us an email and we will work with you one-on-one to make sure we send you off feeling confident and excited with your purchase!

Yours Truly,

Kaeleigh Testwuide
