Some finally pull towards yellow or gray. To speak of emerald green, one can use the little-known adjective of smaragdin!
THE GENESIS OF THE EMERALD AND ITS MAIN DEPOSITS
Emeralds are very rare gems because their formation has required very specific geological conditions, of several natures and at times very distant from each other. Thus, in the Carnaiba (Brazil) deposits, a granitic magma bubble rising from the depths came into contact with the more superficial rocks. Their contact has resulted in different chemical reactions and the migration of certain minerals, according to a process called metasomatosis. The crystals formed at that time, bordering the contact zone, about two billion years ago. The Colombian deposits, on the other hand, are more recent: they developed in geodes between 32 and 65 million years ago, and the proportion of pure and flawless crystals is much greater.

THE ADVICE OF OUR GEMOLOGIST: HOW TO CHOOSE HIS EMERALD? The higher the color of an emerald, the higher the value. The quality of its size is also very important. An emerald is cut in … emerald, pear, cabochon, or cushion. The larger the table, the brighter the stone will be. The angle of the facets conditions the play of light and the apparent color of the gem. The inclusions called "frost", frequent inside this stone, constitute the "garden" of the emerald and do not detract from its quality as long as they are not too numerous: they are on the contrary a pledge of authenticity. So there is no evidence of purity for emerald, as it is used for diamond. Unlike the injection of colored resin, which
denatures the stone, the impregnation in fine oils is an authorized treatment, sometimes used to improve the color or hide some of the inclusions. If you choose an emerald from the Muzo mine in Colombia, ask for a certificate: in fact, this mine does not produce more than fifty jewelry emeralds per week. These are very pure and sought after.

This sacred vase, which appeared in the Arthurian legends of Chrétien de Troyes, was supposed to have collected the blood of the five wounds of Christ during the crucifixion. It was probably related to the Celtic symbolism of the Dagda Cauldron; only the purest among the Knights of the Round Table had the privilege of seeing him.
In his "Natural History", Pliny the Elder praises the emerald as having the most beautiful green color ever, so much so that nothing seems greener after we have contemplated this gem.
