This is the most asked question from our customers when selling their diamond jewelry. The value of a diamond is primarily determined by:

• Carat Weight: The weight of the diamond
• Color Grade: A wide ranging scale of colors affect prices
• Clarity Grade: The clearer the diamond, the more expensive it is
• Shape: Round diamonds are worth more money than fancy shapes such as Princess or Emerald cuts, for example
• Cut Grade: How well your diamond reflects light and sparkles (round diamonds only)
• Brand: Luxury brands such as Cartier, Bvlgari, Tiffany & Co. and more add value

To determine how much your diamond jewelry is worth we need to see the diamond and expertly determine all of these factors. Click the button below to get your bespoke price quote from our experts.
