The name emerald comes from the Greek “smaragdos”, which means green stone. Considered to be the “mother of stones”, the emerald is green.

Emerald generalities

Emerald, from Latin, smaragdus means “heart of stone”. This green colored stone is one of the four precious stones along with ruby, sapphire and diamond. It is a mineral that belongs to the beryl family. With a wide variety of tints depending on its origin, emerald is a very rare gemstone.

It has many inclusions, which makes it highly fragile. Symbol of renewal, spring and hope, emerald has always been a dream. It is the birthstone of people born in May. Also find out how to offer this stone for the emerald wedding anniversary.

First historical traces of the emerald

We find the first traces of the famous green gemstone in Ancient Egypt. Mines near the Red Sea, now drained, produced emeralds used by the Egyptians to make jewelry for queens and pharaohs. If a few years ago the mines of Colombia were full of these extremely prized blue-tinted green beryls, nowadays the most beautiful stones come from deposits located in Zambia, Zimbabwe and Brazil, the world’s largest producer of emeralds.

Belonging to the group of Silicates, emerald is a variant of beryl. But the emerald is distinguished by its green color. This color comes from the presence of chromium, vanadium and iron in its composition. In fact, the emerald colors vary between yellowish green and blue green. On the Mohs scale, its hardness is 7.5 to 8.

Emerald weight and carat

The unit of measure for the weight of gemstones is the carat. A 1 carat emerald weighs 0.20 g and so 1 g gives 5 carats of emerald. The carat weight of an emerald is a very precise measurement that will determine its price: the heavier a stone is in carat, the higher its price (for equal quality).

Emerald has a lower density than the other three gemstones. This ranges from 2.67 to 2.78, while for comparison, a diamond will have a density of 3.52 on average. At equal weight, the green gem will therefore visually appear larger.

The emerald: a stone well-known for its intense color

The second criterion is the green color of the gem. The criteria of hue (color), saturation (intensity) and value (brightness) are taken into account. The color of an emerald varies from pale green with yellow highlights to a deep, slightly bluish green. This criterion is subjective, but generally intense tones are the most sought after. However, clear emeralds often have a lot of sparkle and shine.


Regardless of their quality, all emeralds have inclusions that are poetically called the “garden” or “frost”. These white frosts are one of the characteristics of the green gemstone. They make it possible to determine its origin.

Certain types of imperfections can be valued and crazily sought after by collectors. In higher quality gems, flaws are almost invisible to the naked eye and allow more light to get into the gem.

Shape and forms

Not everyone is an emerald cutter: only experienced stone cutters can boast of cutting even the most fragile of beryls. Before it was customary to cut this precious stone in a step cut, with a large plate and facets with cut sides to bring out the color: it is the “emerald” cut.

If the pear and the oval have also always been particularly popular shapes for green stone, today there is an increasingly frequent demand for the brilliant shape, that is to say round.

Treatments of the emerald

One of the practices of lapidaries is to soak emeralds in natural fine oil to fill in the inclusions. Thus, the stone gets a better shine. This technique is applied on the majority of emeralds and is considered natural even by the main recognized expert laboratories. It does not change the price of the gem in any way.

But be careful, this technique is not to be confused with filling, a treatment based on colored synthetic resin that is injected into the gem. The resin modifies the color of the gem and denatures it, it is a prohibited technique.
