How to Buy Diamonds

Diamonds come in all sorts of shapes and sizes — here is how to find your perfect match.

Like snowflakes, every diamond is different and each one is beautiful in its own right. Diamonds, however, can be graded according to cut, color, quality and carat size. It is the particular combination of these elements that comes into play when you set out to buy the right diamond for you. Each of these factors, alone and combined has an impact on a diamond’s value.

Carat size: The larger the diamond, the higher the price, as they are valued primarily on carat size. Larger diamonds are rarer than smaller ones and therefore the price per carat rises exponentially with the size of the diamond.

Clarity: This refers to the presence of flaws within a diamond. Marks on the surface are called blemishes. Internal marks are called inclusions. The amount, type, size and placement of these imperfections can diminish a diamond’s value — if they are in the center of a diamond, this has a greater effect on light return, for example, than if they are off to the side. The Gemological Institute of America (GIA) clarity scale, the industry standard, contains 11 grades: Flawless (FL), Internally Flawless (IF), Very, Very Slightly Included   (VVS1   and VVS2), Very Slightly Included (VS1 and VS2), Slightly Included (SI1 and SI2), and Included (I1, I2 and I3).
