Emerald

L'emerald is one of the most prized and admired gemstones in the world of jewelry. luxury jewellery. From the beryl group, this gem is distinguished by its intense green colour, which is mainly due to the presence of chromium and vanadium. Emeralds have been synonymous with wealth, beauty and mystery for thousands of years, and they continue to be the stone of choice for top-of-the-range jewellery, particularly in the luxury trade in Thailand, where SMV excels in creating exceptional pieces.

Origin and history of emerald

The emeralds have a rich history dating back to several ancient civilisations. They were particularly prized by the Egyptians, with Cleopatra being one of the most famous lovers of this precious stone. The Romans and Incas, among other civilisations, also revered emeralds for their beauty and alleged mystical properties.

Physical and chemical characteristics

An emerald is a variety of the mineral beryl, with a chemical composition of Be₃Al₂(SiO₃)₆. Its green colour comes from traces of chromium and vanadium. Emeralds have a hardness of 7.5 to 8 on the Mohs scale, making them hard enough to be used in jewellery, but they must be handled with care to avoid cracks and breakage.

Emerald quality criteria

The quality of an emerald is assessed according to several criteria, often summarised by the four Cs: colour, clarity, cut and carat.

• ColourColour is the most important factor. The most precious emeralds have an intense, uniform green hue. The colour saturation should be vivid, and the stone should not be too light or too dark.
• ClarityEmeralds often contain inclusions, known as "gardens". Although these imperfections can reduce clarity, they are often tolerated as they do not necessarily affect the beauty of the stone. An emerald without any inclusions is extremely rare and therefore very precious.
• CutCutting an emerald affects its brilliance and sparkle. Gem cutters have to be particularly skilful to maximise the emerald's beauty while minimising material losses.
• CaratThe carat weight also influences the value of an emerald. The larger the stone, the more precious it is, provided the other quality criteria are also met.
