Discover the world of gems and precious stones

Gems and precious stones, with millions of years of history within them, have become a symbol of luxury, elegance, and sophistication. Their beauty and exclusivity make them true works of art, adorning exquisite pieces of jewellery that reflect personality and are imbued with sentiment.

In this guide, we invite you to explore the fascinating world of gems, their characteristics, properties, and their power to transform any piece of jewellery into an icon of style.

What are gems and precious stones?

Gems and precious stones are minerals that, due to their beauty, rarity, durability, and value, have been used for centuries in the creation of jewellery and other accessories. Although both terms are often used interchangeably, they actually have specific distinctions:

What is a gem?

A gem is any mineral that has been cut, polished, and used to create jewellery or other decorative objects. It is important to highlight that not all gems are precious, and they can be either natural (sourced directly from nature) or synthetic (created in a laboratory).

What is a precious stone?

Precious stones are a specific type of gem that is particularly exclusive and valuable due to its exceptional properties. There are four precious stones: diamond, emerald, ruby, and sapphire.

Semi-precious stones differ from precious stones as they do not reach the same level of rarity and value. However, they still possess great appeal and beauty, making them highly sought-after gems.

Properties of gems

The properties of gems determine the beauty and value of a piece. The following aspects are considered:

• Colour: The hue, saturation, and tone of the gem.
• Clarity: The absence of inclusions or fissures.
• Cut: The shape and facets of the gem, which affect its brilliance and appearance.
• Hardness: Measured on the Mohs scale (from 1 to 10), indicating resistance to scratching.
• Lustre: The amount of light the gem reflects; influenced by its cut.
• Transparency: Whether the gem is opaque, translucent, or transparent.
• Weight: Measured in carats (ct).

These are some of the main properties that classify a gem, but others include chemical composition, rarity, and optical properties.

Guide to Precious Stones

Each precious stone has its own unique properties, characteristics, meaning, and history. Below, we delve into them:

Diamond

Diamond is perhaps the most coveted gem in the world. It stands out for its hardness, ranking 10 on the Mohs scale, and its brilliance, making it a symbol of love and power. While colourless diamonds are the most well-known, they can also be found in black, pink, or green shades, among others.

Formed under extreme pressure and temperature conditions, diamonds have been regarded in many cultures as talismans of strength and protection. Throughout history, diamonds have featured in crowns and engagement jewellery, cementing their status as the most desired precious stone, especially in engagement rings, where they symbolise an eternal and indestructible bond.

Emerald

Emerald is a variety of beryl, known for its characteristic green colour and high appreciation in jewellery. Highly durable, with a hardness of around 8 on the Mohs scale, its colour results from the presence of chromium in its composition, ranging from light to deep green.

This precious stone has symbolised fertility, rebirth, and wisdom across many cultures. For centuries, it has been linked to royalty and power, making it one of the most valuable and coveted gems in jewellery.

Ruby

Ruby is one of the most sought-after stones in jewellery. A variety of corundum, it ranks 9 on the Mohs hardness scale. Its red colour results from the presence of chromium in its crystalline structure, varying from deep red to a brighter red hue.

This stone has been attributed with protective properties, believed to grant courage and strength to its wearer. It also symbolises passion, love, and power. Historically, it has been a status symbol, especially among royalty, and remains one of the most prized stones in luxury jewellery.

Sapphire

Another variety of corundum, sapphire is known for its intense blue colour, though it can also be found in pink, yellow, and green tones. With a hardness of 9 on the Mohs scale, it is ideal for jewellery.

Throughout history, sapphire has symbolised wisdom, nobility, and protection. In the Middle Ages, it was believed to shield its wearer from envy and evil. It has been a favourite among royalty and aristocracy and continues to be a preferred gemstone for engagement rings and other high-end jewellery pieces.
