What determines the value of emeralds
The value of emeralds is determined by 4C
- Carat (Weight)
What mainly determines the value of emeralds is the color. We find them in shades ranging from yellow-green to blue-green, with the main shade being green to medium to dark tone. The mixture of yellow and blue are the colors that actually give the green color to the emeralds. The darker the green color they have the more expensive they are.
Emeralds tend to have several cracks and inclusions on their surface. They are evaluated with the eye without the use of a magnifying glass in contrast to diamonds. Inclusions and cracks are unique to each emerald. If an emerald has no visible inclusions in the eye it is considered flawless. Also, emeralds without cracks on the surface are extremely rare.
The most common way to cut emeralds is cabochon. We also find them in baguette (square), princess and oval cuts.
Carat is the international unit for measuring the weight of precious stones. More specifically, one carat is equal to 200mg. In emeralds that have the same specifications (purity, color, cut) as the carat weight increases, so does their price.
