Jewellery Glossary

When choosing a fine piece of jewellery, one of the first elements to understand is the metal from which it is crafted. Not all golds are the same, and the difference extends far beyond price alone. It lies in the character of the metal, its behaviour in contact with the skin, and its ability to preserve its beauty over time.

Diamonds, rubies, emeralds and sapphires are among the most celebrated and sought-after gemstones in the history of jewellery. Their rarity, beauty and enduring value have made them the centrepieces of prestigious collections and iconic creations. Understanding these gems means looking beyond their names and appreciating the characteristics that define the quality and individuality of each specimen.

The world of coloured gemstones represents one of the most fascinating and complex areas of jewellery. Certain varieties possess exceptional gemological characteristics and levels of rarity, making them highly prized by collectors, connoisseurs, and high jewellery houses.

Cut is the only characteristic of a gemstone that does not originate in nature but is shaped by human expertise. Through the skill and artistic vision of the cutter, a gemstone can fully express its optical and chromatic qualities. An exceptional cut can enhance even a modest stone, while an inadequate cut may diminish the beauty of a gem of outstanding rarity.

Traditional goldsmithing techniques form the foundation of high-quality jewellery creation. Many of these processes require highly specialised expertise, years of training, and an in-depth understanding of precious metals and gemstones. Their execution plays a decisive role in the aesthetic, technical, and artisanal value of a jewel.

Each category of jewellery possesses its own history, purpose and tradition. Understanding these distinctions offers a deeper appreciation of the language of high jewellery and the cultural significance embodied in each creation.

Gemological certification and supporting documentation play a fundamental role in the assessment of gemstones and jewellery. Reports issued by the leading international laboratories provide objective information regarding a gemstone's characteristics, authenticity and any treatments it may have undergone, forming the basis for an informed evaluation.

Gemology combines mineralogy, physics and optics to explain the characteristics that make gemstones unique. Properties such as colour, brilliance, transparency and optical phenomena arise from the interaction between light and the internal structure of a gemstone.
