What is my diamond ring worth?

Diamonds are inherently complex items to value, with over 20 factors to consider. They require expert gemological knowledge. The main factors that will affect what your diamond ring is worth are the following:

  1. Certificates: Are the diamonds ring certified by a reputable lab? The most accurate diamond grading laboratory in the industry is the GIA.
  2. Condition: Look for any chips or abrasions as these will affect price.
  3. Market Conditions: Market demand changes over time and affect value. Diamond shapes will fall in and out of fashion over the years.
  4. The 4 C’s: color grade, clarity grade, cut grade and carat weight. These four C’s form the fundamentals of diamond grading. Color grades range from D – Z, while cut grades range from IF -I 3. Cut grades only apply to round brilliant diamonds and range from Excellent – Poor. And carat weight is the weight of the stone.


Where to find this information:

The 4 C’s can be found on most diamond paperwork, such as a diamond certificate or appraisal. To get your bespoke price quote, click the button below and we will be in touch.
