At The Gold Guy buying diamonds is in our blood. We’ve been family owned and operated since 1952. All of our diamond buyers have an extensive knowledge of gems and gemstones based on experience and are highly trained through the Gemological Institute of America. Training at the GIA gives our diamond buyers a thorough knowledge to objectively compare and evaluate diamonds in order to determine their true value. A diamond’s value is determined by 4 qualities: carats, color, clarity, and cut.


  • Carat: A diamond’s weight is measured in metric carats. Even a fraction of a carat can make a considerable difference in value
  • Color: Diamond color is all about what you can’t see. A diamond’s value increases the closer it approaches colorlessness – the less color, the higher their value*
  • Clarity: Diamonds are formed under immense heat and pressure which can cause unique birthmarks, either internal (inclusions) or external (blemishes) that affect value.
  • Cut: The precision and style of cut will also affect the diamond’s value.


*There are exceptions to this rule with fancy-color diamonds such as pink or blue.
