A buyer's guide to pink diamond rings

When thinking of diamonds, most people think of the white, colourless variety. However, diamonds come in a range of colours: blue, yellow, brown and pink.The rare pink diamond is one of the most valuable of all diamonds and natural pink diamonds rings can be more expensive than similar rings with white diamonds.

How diamonds are graded

Pink diamonds
Pink diamonds come in a range of different shades, from very light and pale pinks to dark and deep tones. The deepest pinks are the most expensive on the market. If you are planning to invest in a diamond ring, it is a good idea to know something about how diamonds are graded and what makes one diamond more valuable and expensive than another. Classifications of diamonds
Diamonds are classified and graded according to the so-called "four C:s": carat, clarity, colour and cut. The carat is familiar to most people and it tells you the weight of the diamond. Large diamonds are more difficult to find than small ones and diamond engagement rings with one large diamond (at least over 1 ct) are always more valuable than rings with several small diamonds.

Diamond cut, clarity and colour

Cut of the diamond The cut of a diamond is what makes the diamond reflect light and sparkle. A good cut makes a diamond brilliant and sparkling, but a poorly cut diamond can look lifeless. A cut which is too deep or too shallow can severely affect the diamond's overall quality. Clarity feature of the diamond Clarity depends on how flawless the diamond is. The clearer a diamond is, the more brilliant and sparkling it looks, and the best diamonds are flawless both on the inside and on the outside. Most diamonds have some minor flaws, but the quality depends on the amount of the flaws on the inside and on the outside, and on the size of possible inclusions.
The colour of the diamond Colour is the fourth of the "C:s". White, colourless diamonds are usually the most sought after and valuable because of the unique way they reflect light. Diamonds with brownish or yellowish tones are less valuable and less expensive, because the off-white surface absorbs some of the light and makes the diamond less brilliant. However, the rarity of natural pink diamonds make them more valuable than other diamonds. Synthetically coloured diamonds exist on the market, but they are never as valuable as natural gemstones. If you are looking for a natural pink diamond ring, be prepared to invest money, and make sure that you are buying from a reputable jeweler who can guarantee that you are buying a natural and not a synthetically coloured diamond.
