Hello,
I am Kaeleigh Testwuide, founder and diamond expert at The Diamond Reserve. Thank you so much for visiting with us! My number one goal is to get you educated on all the dos and don’ts of buying a diamond, making sure you get the best diamond for the best value!
There is so much information out there regarding diamonds and a lot of mistrust when buying a diamond. At The Diamond Reserve we will give you the truth, answer all of your questions, and ensure that you feel confident when you select a diamond. Buying a diamond and an engagement ring does not need to be stressful, it should be fun and exciting, and that is exactly how it feels when you work with us.
Are you thinking about popping THE question, upgrading your diamond, redesigning your setting, or looking for a special gift? Send me an email and I will work with you personally to make sure we send you off feeling confident and excited with your purchase!
Yours Truly,
Kaeleigh Testwuide
