Welcome to Old World Diamonds

A note from Adam

We are the world’s largest vendor of genuine antique diamonds. All of the diamonds you see on our website are from our own inventory and not just a compiled list from many sources. If you have interest in a stone that has no picture or video, please let us know and we will be happy to take one for you. Some of my personal favorites are listed here. Be sure to check often as they will change. Thank you again for visiting Old World Diamonds.

Our Antique Diamonds

Three beautiful genuine antique cuts, Old European, Old Mine, & Antique Cushion.

Old European


The Old European diamond has a very small table, a heavy crown, and great overall depth. This diamond cut was the fore-runner of the modern brilliant cut. Like the modern round brilliant, the Old European diamond has a circular round shape.

Old Mine


Old mine cut diamonds date back to the 1830's and were common up until the turn of the century. They are the earliest form of the modern brilliant cut. Old mine diamonds are mostly off-round in shape with a high crown, small table and open culet.

Antique Cushion


The cushion cut diamond was one of the most popular cuts of diamonds ever. For more than 70 years from 1830 to the turn of the century this was how diamonds were cut. The cushion cut has a rectangular to square shape with rounded corners.

View the OWD Collection




It is a rarity in the customer service industry for someone to excel beyond your expectations but OWD and Adams team manage to do that for us! My husband and I had a custom 10 year anniversary ring made along with a matching wedding band. Adam helped us select a beautiful OEC stone that is absolutely unique, mesmerizing, and high performing. He even went out of his usual sourcing channels to procure elongated French cuts just to allow this dream ring to come to reality. The custom setting process was a worry free procedure as there weren\'t any communication issues, and there was the opportunity to make adjustments even after seeing the final product. Adam and OWD has gained a customer for life and I am so thankful and in awe of the beautiful rings that are pieces of art work on my fingers! The stone and the workmanship was top notch. Enjoying this ring and wedding band for many years to come and already designating OWD as my jeweler for all our future projects. We can\'t thank you enough, Adam!

Selling Diamonds?

Old World Diamonds buys all types of diamonds. We buy both antique and modern diamonds of all shapes, sizes and qualities. The best way to start is to tell us everything you know about your diamond like shape, weight, color and clarity. If your diamond has a grading certificate such as EGL, GIA or AGS, this will make the process very easy. We can offer you a quote just be viewing a copy of your certificate. Please keep in mind appraisals generally show a much higher value than what your diamond will be worth in the second hand market appraisals. Appraisals are mostly meant for insurance replacement reasons. Old World Diamonds makes it very simple and safe to ship your diamond to us for evaluation. We will wire you your money the same day or overnight you a check! Please call or email with any questions.
