Best Prices for the Best Diamonds

Our website carries many diamonds from many reputable vendors across the world. Derco Jewelers has always strived to provide the best service, products and prices possible. We focus on a high turnover rate to ensure we can provide our clients with the best prices. If there is ever any question about the quality of a diamond our international agents will be available to inspect the diamond and ensure that it is of the best quality.

Conflict Free Diamonds

All of our products at Derco Jewelers are made in house at our manufacturing department or provided from reputable dealers in the United States. All of our diamonds are conflict-free, ethically sourced and follow the Kimberly Process Certification Scheme. The Kimberly Process, established in 2003, ensures that diamond purchases are not financing groups in areas with ongoing conflicts. All of our diamonds are provided by reputable vendors from areas outside of said ongoing conflicts.
