Diamond Buying Tips

DiamondsThe hardest and brightest of all gems, the diamond is considered the King of gems. No wonder then that most women aspire to own a few of these precious rocks to adorn their fingers, ears or arms. But beware; on your quest for bling you will encounter many Jokers out there posing to be the King.

So how do you find a genuine diamond that will last "forever"?

Here are a few Tips to help when you go shopping for these Precious stones..

Last Updated -1st June 2007

What is a diamond?

A diamond is pure carbon, but with three extraordinary characteristics. It has the unique power to reflect light. It is the only mineral, whose consistency is based on one element, and therefore the purest of all gems. And, it is the hardest, transparent substance known to man.

Who produces diamonds?

80% of diamond production and trade worldwide is managed / controlled from a company known as 'The Diamond Corporation' or 'De Beers Consolidated Mines Limited'.

What are the 4 C's?

The 4 C's are colour, clarity, cut and carat.

COLOUR: The purest and rarest diamonds are virtually colourless. Although many diamonds may appear colourless to the untrained eye, the majority contain very slight traces of yellow, brown or grey. A stone's beauty and value usually increase dramatically the more colourless it is. The spectrum ranges from light yellow, 'Z,' to totally colourless, 'D.'

CLARITY: It is possible to find some imperfections in almost every diamond: tiny feathers and clouds - inclusions - that affect a diamond's value. Clarity grades range from 'I' (imperfect) to 'FL' (flawless). A diamond is said to be 'flawless' if no inclusions or superficial blemishes can be seen under a standard 10-power jeweller's loupe. Truly flawless diamonds are extremely rare.

CUT: More than any other quality, cut determines the fire and brilliance of a diamond. In order to maximize this fire and brilliance, the diamond cutter must place each of the stone's facets and angles in exact geometric relation to one another. On a classic round brilliant-cut diamond, for instance, 57 or 58 facets must be precisely aligned. The seven most popular cuts are:

  1. Round
  2. Princess
  3. Heart
  4. Marquise
  5. Emerald
  6. Pear
  7. Oval

CARAT: Carat is the gemmologist's standard measure of a diamond's weight. But size alone is almost meaningless unless you consider Cut, Clarity and Colour. However, size does increase the value of a good quality diamond for the simple reason that large stones are rarer than small ones. In one million mined stones, only one weights a carat or more.
It is the combination of these 4 criteria, which determines the quality and the brilliance of a diamond - and its value.

How does one evaluate the quality of a diamond?

Only 20% of all mined diamonds are suitable for the jewellery industries. The quality evaluation of jewellery-diamonds requires lots of expertise and experience. The four C's make the value of a diamond.

How does one identify fake diamonds?

You can see through zircons (glasslike stones) as you can through a window. If you place zircons on paper, you allow the print to be seen. When you place it on something black, you can see the black colour through it. This does not happen with diamonds. The reflection from the facets scatters light everywhere.

If you look at the stone through a 10x magnifying glass and see numerous air bubbles, the stone is glass.

Reputable jewellers will give an honest answer when you ask them about the authenticity of the stone. Ask whether it is a genuine diamond, cubic zircon, maisonette or another synthetic substance.

Zircon and other cheap stones are sometimes set in inferior metals.

The stone should be certified by an official grading institution. It should also have a certificate which indicates the value and characteristics of the stone.
