Welcome to The Diamond Bank!
We are an independent group of merchants dedicated to providing our customers with the best possible value in their diamond purchase. We have many years of experience in this business and have one of the largest selections of certified diamonds, bringing to you the best value for your money. We are confident that once you compare our diamond quality and value to anyone else's, you too will become a Diamond Bank customer.
We sell only EGL USA, GIA, AGS, certified diamonds, and we supply you with a certificate for safe keeping. We recommend that you only buy a diamond if it has a certification from one of the above laboratories. A certification is only a certified grading report, not an appraisal. We also provide a free appraisal with your diamond purchase. We ship Fed-Ex or Certified Mail - Insured.
