February's Birthstone: Amethyst

Formed in volcanic rock, amethyst is a variety of quartz that ranges in colour from delicate lilac to deep, rich purple. Its name comes from the Greek word amethystos, meaning "not intoxicated" — it was once believed to prevent drunkenness and promote clarity of mind.

A symbol of piety and spiritual protection, amethyst has long been used in religious jewelry, including the bishop's rings of the Catholic Church. Its regal purple hue and rich history make it one of the most meaningful and storied gemstones in fine jewelry.


The Toughest Gemstones for Your Jewelry

The durability of a gemstone is measured using the Mohs Scale of Mineral Hardness, which ranks materials from 1 (softest) to 10 (hardest) based on their resistance to scratching and wear. Here are the toughest gemstones to consider for everyday fine jewelry:

1. Diamond — 10
The hardest naturally occurring material on Earth. Composed of carbon atoms arranged in a crystal lattice, diamond is renowned for its unmatched brilliance and durability, making it the ultimate choice for fine jewelry designed to last a lifetime.

2. Moissanite — 9.25
Second only to diamond in hardness, moissanite is a sustainable and increasingly popular alternative. It offers exceptional brilliance and fire, often indistinguishable from diamond to the untrained eye.

3. Corundum — 9
The mineral family that encompasses both sapphire and ruby — two of the most coveted gemstones in the world. Renowned for their exceptional hardness and vibrant colours, corundum gemstones are among the most durable choices for everyday wear and heirloom pieces alike.

Understanding a gemstone's hardness helps you make informed choices when designing or purchasing fine jewelry. Whether you're creating a custom piece or simply curious about the stones you already own, our team is always happy to guide you.
