Diamond Valuation

Colour and Price

The first thing that you need to know is that there is a direct relationship between the colour and the price tag of a diamond. The most valuable diamonds are the purest stones. This means that they are clear and colourless and appear a very bright white to the human eye. The total lack of tint makes for a rare and coveted stone. A person who is not working with diamonds and other precious stones for a long amount of time may not be able to identify whether a yellowish tinge is present, or differentiate one diamond’s shade from the other.

Diamonds are essentially made from carbon atoms that have been subjected to extreme pressures and temperatures in the bowels of the earth. While this is happening, other naturally occurring trace elements can make their way into the mix. In the microscopic level, they change the atomic structure of the diamond. Their intrusion is manifested outwardly and is perceived by human observers as the presence of colour

Discerning colour differences

The three most common tints of diamonds are grey, brown, and yellow. The strength of the tint ranges from quite obvious and undeniable to almost imperceptible. The easiest way to spot a yellowish diamond is when it is placed next to a pure white diamond. To the untrained eye, the distinction may not be as evident when the two are placed separately. The yellowish tint may escape the observer altogether if the diamond is presented alone and without another stone present for comparison.

This observation becomes relevant when the setting involves more than one stone. If the design for your engagement ring involves a center diamond flanked by two others placed on either side, make sure that the stones chosen have exactly the same tint. The alternative is to ensure that the smaller diamonds have a darker tint than the center stone so that the others do not overshadow the center stone that is being highlighted.
