Tips for Choosing a Diamond
There are four main criteria when buying a diamond, they are the 4C’s: Carat weight, clarity, color and cut.
When selecting your diamond, it is smart to use a lamp that produces light that is as close as possible to that of the day. In most jewelry shops and stores, you can find these broad spectrum lamps that make it easier to tell the value of the diamond. Though keep in mind that this light is artificial and once outside, facing the light, the glow may be less.
It is essential to choose your diamond with a light “cold” that mimics the brightness that comes from the outside North between 12 and 14 h.
Typically a certificate may accompany your diamond. This report includes all the gemological characteristics of the main diamond and it is an authentic identity card for your stone. The laser engraving certificate number on the girdle (the circumference) of the stone is a must. It allows full traceability of your diamond. You can learn to recognize your diamond for yourself through a microscope at a magnification of 15 times.
You should beware of artificial, treated stones. It is a known fact that diamonds that are “Clarity Enhanced” or “Enhanced Color” have been artificially modified and the price of such a diamond drops sharply by about 70 to 80%. An individual who buys a diamond without a certificate is taking the risk of unwittingly buying an artificially treated stone.
It’s not just the 4 principal diamond criteria (weight, clarity, color, size) to consider when buying a diamond. Indeed, the proportions of the diamond, the finishing and the fluorescence are also very important criteria.
1) Fluorescence:
Choose diamond fluorescence “none” or “nil” (null), “slight” (low), or “medium” for color D, E or F.
Avoid diamonds of fluorescence “strong” (strong), it would give a milky stone color. Choose a fluorescence of “strong” for diamonds with colors H, I, J; it will improve the brightness and the color of the stone.
2) Proportions:
Choose a diamond with proportions of “very good” (very good). This will guarantee optimum brilliance.
3) Finishes
Choose a diamond finishes with “very good” (very good) or “good” (good).
