An Introduction
Gemstones have captivated us for centuries with their vibrant colors, unique properties, and timeless allure. Whether you’re drawn to the deep blue of sapphire or the fiery hues of ruby, understanding gemstones and their Mohs scale hardness helps ensure your jewellery remains beautiful and durable for years to come.

Mohs Hardness Scale
The Mohs scale of hardness measures a gemstone’s resistance to scratching, ranging from 1 (softest) to 10 (hardest). Harder gemstones are more durable, making them ideal for everyday wear, while softer stones may require extra care.

Gemstones
Diamond
Diamonds are traditionally colourless but available in shades like yellow, pink, and blue.
Mohs Hardness: 10 (Hardest).
Diamonds are the hardest natural substance on Earth, making them exceptionally durable and brilliant. They’re a classic choice for engagement rings and timeless jewellery.

Gemstones
Ruby
Rubies are a deep red, ranging from pinkish to purplish hues.
Mohs Hardness: 9.
A member of the corundum family, rubies symbolises passion and love. Their durability makes them ideal for everyday wear.

Gemstones
Sapphire
Sapphires are most famously blue, but also available in pink, yellow, and green.
Mohs Hardness: 9.
Another corundum variety, sapphires are versatile and durable, perfect for engagement rings and statement pieces.

Gemstones
Emerald
Emeralds are vibrant green, often with natural inclusions known as "jardin."
Mohs Hardness: 7.5–8.
A type of beryl, emeralds exude sophistication. They’re softer than diamonds and corundum, so they require gentle care.

Gemstones
Aquamarine
Aquamarines are typically a pale blue, but can vary to slightly darker shades.
Mohs Hardness: 7.5–8.
Also a beryl variety, aquamarine evokes the serenity of the sea. It’s durable enough for occasional wear but needs protection from hard impacts.
