Sapphires: composed of corundum, are renowned for their durability, second only to diamonds. The presence of trace elements creates their vibrant hues, with iron lending them their mesmerizing blue shades. In antique jewellery, Burmese sapphires are particularly prized for their intense royal blue colour, a testament to their rarity and quality. Gemmologists often marvel at the star sapphires, a phenomenon where needle-like inclusions create a captivating star-shaped reflection, adding an ethereal quality to these vintage gems.

Rubies, also corundum crystals, owe their red hues to chromium. The intensity of their color is a key factor in their value, with the finest rubies displaying a vivid, almost “pigeon blood” red. Antique rubies often showcase unique phenomena like asterism, where intersecting needle-like inclusions create a star-shaped pattern on the surface of the gem. This natural wonder, combined with their passionate color, makes antique rubies highly sought after by gem enthusiasts and collectors alike.

Emeralds: Green Hues of Nature
Emeralds, belonging to the beryl family, derive their enchanting green colour from chromium and vanadium. Unlike many gemstones, emeralds often contain visible inclusions, known as “jardin” or garden, which are accepted as part of their character. Antique emeralds, particularly those from Colombia, are celebrated for their lush green hue and fascinating internal landscapes. Gemmologists appreciate the “three-phase inclusions,” where gas, liquid, and solid materials are trapped within the gem, providing a unique fingerprint of its formation process.
Diamonds: Timeless Brilliance

Diamonds, composed of pure carbon atoms arranged in a crystal lattice structure, are renowned for their brilliance and hardness. Gemmologists assess diamonds based on the “Four Cs”: carat weight, cut, colour, and clarity. Antique diamonds often feature unique cuts, such as the rose cut or old mine cut, which reflect the styles prevalent in their respective eras. Gemmological marvels like “inclusions in motion” and “fluorescence,” where diamonds emit a soft glow under ultraviolet light, add to the allure of antique diamond jewellery.
