While buying emeralds or emerald ornaments, there are a few points you should keep in mind. These are basically the 4 Cs of Emeralds.
Emerald Buying Guide on the basis of Colour, Clarity, cut & carat
1. Emerald Colour
For emeralds, color is the most significant quality feature. Emeralds with colors ranging from bluish-green to pure green, with vivid color saturation and a tone that isn't too dark, are considered the most desirable ones. The most valuable emeralds are transparent. Their color should be evenly distributed, with no color zoning evident to the naked eye. The color of emerald also varies because of the geographical location from which it was mined.
2. Emerald Clarity
Inclusions that are visible to the naked eye are common in emeralds. As a result, members of the jewelry trade and some consumers are aware of it and accept the existence of inclusions in emeralds.
3. Emerald Cut
Emeralds are hard but brittle stones. As a result, when they're mined, they're likely to have fractures. The optimal approach to cutting a raw stone is determined by the placement of these cracks. Its perceived color can also be influenced by how it is cut. Well‑cut stones maximize the beauty of the emerald's color to create a bright, lively stone.
The emerald cut, which is a square or rectangular step cut, is the most popular cut. The shape and weight of the natural emerald are maximized with this cutting.
4. Emerald Carat
The weight of a gemstone is measured in terms of carats. Emeralds come in a variety of carat weights. A stone with a higher carat weight is intended to be more expensive. Hundreds of carat emeralds can be found in museums and private collections. At the other end of the spectrum are fractions of carat emeralds. When comparing quality to quality, the price of an emerald can skyrocket as the size increases.
