Our Guarantee

  • For the protection of your investment, your diamond and jewelry should only be obtained from an established and reputable jeweler.
  • Unlike other jewelry stores all of our jewelry is designed and crafted by our in-house jewelers. Therefore any modifications that our clients desire can be made on-site (we don't have to send our jewelry out for changes). By having in-house craftsman we can guarantee your satisfaction.
  • If you are looking to make that investment, we offer you free advice, whether you are buying or selling. On average, diamonds purchased from Diamond Jewelry Company have been appraised at double the selling price.
  • Each diamond comes with an Internationally Accepted Certificate (GIA or EGL).
  • As a leading supplier, with offices world wide, we can provide valuable insight into the history, cutting, polishing and grading of diamonds for those interested in expanding their knowledge before making a sound investment.
  • We offer a thirty day exchange on all of our diamonds or you can upgrade at any time at the full purchase price.
  • Call today and enjoy a pleasant and fascinating visit in a relaxed atmosphere.
