What is my diamond worth?

Each diamond is over 1 billion years old and is as unique as a fingerprint. When it comes to valuing them, experts use the 4 C’s method: cut, clarity, color and carat. If the diamond is not attached to any jewelry, it will be assessed on the 4 C’s, age and provenance. When it comes to the cut or shape of the diamond, round brilliant cuts seem to carry the higher value but other cuts such as Old Single, Old European, Mazarin, Peruzzi, Princess, Cushion, Heart, Tear, Marquise, Radiant, Asscher, Emerald and Oval cuts have consistent demand in the market. A professional appraiser would use the GIA cut grade system to determine the worth of the cut accurately. Condition of diamonds is also important. Although diamonds are the hardest natural substance known to man, they might have cleave or break on the edge directions. The carat of the diamond is certainly important as well, however the clarity and color is actually more essential to the value of the diamond. If a diamond were high in carat but low in quality, it wouldn’t be worth much more than a quality sapphire. It is essential that a professional diamond expert conduct the valuation in order to have the best idea about the market value and estimate price at auction. If you want to have a diamond appraisal fill out our form and send us detailed pictures of the diamond and if applicable original box and certificate.
