Customer Testimonials

We have purchased custom and non custom items here. We always have a grand time in the store and first class service! Diamond Marquise was recommended to us by other friends and family who have had nothing but the best experiences here!

Natalie

Great store with an excellent selection of everything from traditional to truly unique to completely custom. Been a customer for over 10 years and have had nothing but great experiences and service. They are super knowledgeable and can help you find or create anything you are looking for. Not to mention they are there to assist if you have service needs both right on the island and in the US.
Thank you Diamond Marquise!

Mr. Phillip and his staff are the absolute best. We have been shopping at Diamond Marquise for over 10 years. All of my jewelry pieces are absolutely gorgeous. He has custom made rings for our family as well. We would never buy jewelry anywhere else! We look forward to visiting each year!
