Before selling your diamonds (Buyers and Sellers Do’s and Dont’s).

  • All diamonds and or jewelry should be viewed in front of the seller. Do not let a diamond dealer or buyer inspect anything that you have in other rooms or offices.
  • Be worrisome if your diamond expert is calling multiple people on the phone to come and look at your diamond. This tells you he isn’t proficient at buying diamonds and will need help or partners to facilitate a purchase. Also the more people are in on the deal the less money you will be offered on your diamond.
  • Beware of commission based workers. Diamond buyers play a very integral part of a jewelry/ diamond buying office. If you are commission based, they will look to make low offers. Our suggestion is to ask to speak to an owner or a partner of that establishment.
  • Overall atmosphere. Do you feel relaxed and comfortable in the diamond office? Do you feel like you have enough privacy and security? These are some of the questions you need to ask yourself. A professional diamond jewelry or buying office should look clean, secure, and private. Your business shouldn’t be done in front of random people coming and going. You should be dealt with in a professional and serious manner only.
  • Does this diamond buyer have the financial capabilities to purchase jewelry or diamonds on the spot? If you are offered a Cash Only payment be ware. Most fly by night companies offer Cash payment only because they may not open tomorrow. A reputable diamond buyer will offer Check, Wire Transfer, Direct Payment and or Cash.
  • Does your diamond dealer know what your are selling? If your are selling Diamonds or Jewelry designed by Graff, Van Cleef and Arpels, Tiffany and Co, Cartier, Chopard, Bvlgari your diamond dealer should let you know.
