    Kaeleigh was extremely easy to work with and a true expert at her craft. She made sure that everything was within the budget I gave her, and quickly tracked down exactly what I was looking for albeit rare. I highly recommend her.

    I would like thank Kaeleigh for designing the perfect engagement ring!!! I had been looking for a couple of months but could not find the one that I liked, until I found The Diamond Reserve. Kaeleigh was very helpful and worked with me to design a beautiful ring.
