A Guide to Precious Gemstones

In the luxury jewellery space, few things captivate the imagination like precious gemstones. 

Whether you’re looking to make a personal statement with a piece of jewellery or seeking an investment that will stand the test of time, understanding the unique characteristics of each gemstone is essential. Here’s a detailed guide to some of the most sought-after precious gems.

Diamonds

Diamonds are more than just a girl’s best friend; they are a universal symbol of love, commitment, and strength. Renowned for their unparalleled brilliance and hardness – rated a perfect 10 on the Mohs scale – diamond is the hardest natural substance known to man. 

The appeal of diamonds lies not just in their durability but also in their versatility. Whether set in platinum, gold, or silver, diamonds can be fashioned into a variety of jewellery styles, from classic solitaire rings to contemporary men’s diamond earrings. The four Cs – carat, cut, colour, and clarity– are the standard by which diamonds are judged, with the highest value placed on stones that are large, well-cut, colourless, and flawless.

Historically, diamonds have been associated with royalty and power. The famous Koh-i-Noor diamond, now part of the British Crown Jewels, is one such example. For centuries, diamonds have been coveted for their perceived ability to bring strength, invincibility, and clarity to those who wear them.

Rubies

Rubies, with their intense red hue, are often associated with love, passion, and vitality. This fiery gemstone is second only to diamonds in hardness, with a rating of 9 on the Mohs scale. The most prized rubies are those with a deep, vibrant red known as “pigeon’s blood”, a colour so rich that it seems to glow from within.

Rubies have been revered throughout history, particularly in Asian cultures, where they were believed to protect their wearer from evil and bring good fortune. In ancient Burma, warriors would implant rubies into their skin in the belief it made them invincible in battle. Today, rubies are most commonly set in rings, necklaces, and bracelets, often surrounded by diamonds to enhance their dramatic colour.

Sapphires

Sapphires are best known for their stunning blue hues, although they can come in nearly every colour except red (which would make them rubies). The most valuable sapphires display a rich, velvety blue and are sourced primarily from Sri Lanka, Madagascar, and Myanmar. 

Throughout history, sapphires have been linked to wisdom, royalty, and divine favour. The British Crown Jewels feature several famous sapphires, including the St. Edward’s Sapphire, which dates back to the 11th century. Modern jewellery trends often pair sapphires with diamonds in rings, earrings, and pendants, where their deep blue colour adds a touch of sophistication and depth.

Emeralds

Emeralds are prized for their lush green colour, a hue that symbolises renewal, growth, and prosperity. With a hardness of 7.5 to 8 on the Mohs scale, emeralds are somewhat more delicate than diamonds, rubies, or sapphires and should be worn with care to avoid scratching.

The most coveted emeralds come from Colombia, where they are known for their deep green colour with a slight blue tinge. Historically, emeralds have been favoured by royalty, particularly in Ancient Egypt, where Cleopatra was known for her love of the stone. Today, emeralds are often set in intricate designs that highlight their rich colour, such as in cocktail rings, statement necklaces, and earrings.
