A loose diamond in simple terms is a diamond that has been cut and polished. When diamonds are mined from the ground, they are usually rough and without shape, and hence not so shiny and attractive. Hence, to fetch a good price in the end market, they have to be cut and polished to give them a definite shape, a smooth surface and a shinier look, and that’s when they are referred to as loose diamonds.
How To Evaluate Loose Diamonds
Just like everything else, diamonds also come in different qualities, shapes and sizes. As such, there are various aspects used to grade diamonds, with the most important aspects being the 4 Cs, which are the cut, colour, carat weight and clarity. It is these aspects that are put into consideration by buyers shopping for diamonds and appraisal companies before they certify diamonds. These four Cs are however best evaluated in loose diamonds. It is these four Cs that determine the diamond’s beauty and desirability, and as such, it is these four Cs that determine its cost. Evaluating a diamond using these concepts isn’t hard; here is how doing it.
1. Carat Weight
The weight of diamonds is measured in carats, with one carat being equivalent to 200 milligrams. Naturally, the more the carats a diamond have, the higher its price. The size of the diamond also has an influence on its price with respect to weight. Big diamonds are not as common as small ones, and so are more expensive. You may find loose diamonds with fewer carats than small diamonds but still more expensive. Just like is the case with small diamonds, the heavier a large loose diamond is the more expensive it is.
A diamond is associated with clarity and shininess, and as such, a diamond with defects in clarity is, best part, disappointing. It doesn’t feel perfect, and it isn’t. What affects a diamond’s clarity? The most common defects found in loose diamonds are spots and inclusions. These flaws have formed over the years as the diamond is formed and may be anything-including bubbles, non-diamond minerals and cracks inside the diamond’s body. Regardless of its size, a flaw is still a flaw, and it makes the diamond imperfect and as such, it is good to determine a diamond’s clarity well before purchasing it.
The cut of the diamond is responsible for giving it its brilliance, and as such, the cut is the most important aspect in evaluation of loose diamonds. When a diamond is cut properly, light enters it and reflects from all sides of the diamond before getting out, making it brighter. A poorly cut diamond on the other hand leaks out light from the sides and the bottom, making it not so bright. Diamonds can be cut in different shapes, with the most common shape being the shape of a compressed pyramid stacked in an inverted pyramid. There are however other shapes like the emerald side (rectangle), oval, heart-shaped, marquis and princess (square).
Diamonds come in different colours, like blue, red, brown, yellow, purple and colourless. The colour is formed as the diamond forms over the years and is irreversible. Everybody has a taste and preference, but if you want a really shinny diamond then the colourless one is the best since it does not block entrance of light.
These four aspects are the most important factors to consider when you are looking to buy loose diamonds.
