Emeralds are made from the mineral beryl.Its green colour comes from chromium or vanadium.

The word "emerald" comes from the Greek smaragdus meaning "green".
We choose to buy our emeralds from Colombia.

How to assess a Emerald's quality and value?
Our gemmologist evaluates emeralds in a similar way to diamonds – by clarity, colour, cut and carat weight.
Experienced gem dealers like ours, with good industry contacts and robust buying power, get the best emeralds at the best prices.
They know how to look for emeralds with minimal inclusions, intense green colour and an expert cut.
These qualities reveal an emerald's sought after "inner glint".
Emerald colour varies from yellowy-green to bluish green. But the primary colour, or hue, is green. The "greenness" of an emerald may vary greatly from light to dark – the key is to look for vividness of colour, rather than a specific tone.
One carat always equals 0.20 grams. However, the bigger the emerald gets, the more its carat price will rise. This is because large emeralds with good clarity and colour are much rarer than small emeralds of the same quality.
Glass-like, entirely clear emeralds are very rare. If one is found, only wealthy collectors can afford them. Very slight natural inclusions are therefore accepted in commercial grade jewellery. To get best value for your money, our gem expert recommends buying emeralds with hardly noticeable natural inclusions.
A skilled emerald cutter knows how to coax a perfect gemstone out of a rough emerald. A superlative cut disguises inclusions and shows off the gem's desired inner glimmer
