What Is Moissanite? How It Compares to Lab-Grown and Natural Diamonds
What Is Moissanite?
Moissanite: A Brilliant Diamond Alternative
Moissanite is a gemstone that closely resembles a diamond in appearance, offering exceptional brilliance, durability and beauty at a more accessible price point.
Originally discovered in a meteor crater, moissanite is now expertly grown in laboratories using advanced technology. While it shares many visual characteristics with a diamond, moissanite has its own unique composition and optical properties.
A diamond simulant is a gemstone designed to replicate the appearance of a diamond without sharing the same chemical structure. At Harper Jewellery, we exclusively use premium-quality moissanites sourced from leading laboratories worldwide.
Durability & Composition
Natural and lab-grown diamonds are composed of pure carbon arranged in a crystal structure, making them the hardest known gemstone with a Mohs hardness rating of 10.
Moissanite is composed of silicon carbide and has an impressive Mohs hardness rating of 9.25, making it highly resistant to scratching and suitable for everyday wear.
This exceptional durability makes moissanite an excellent choice for engagement rings, tennis bracelets, tennis necklaces and fine jewellery designed to be worn and enjoyed for years to come.
Brilliance & Sparkle
One of the most remarkable characteristics of moissanite is its brilliance.
A gemstone's refractive index measures how effectively it bends and reflects light. Diamonds have a refractive index of approximately 2.42, while moissanite ranges from 2.65 to 2.69.
This higher refractive index allows moissanite to produce exceptional sparkle and fire, creating the distinctive flashes of rainbow-coloured light that many jewellery lovers admire.
Why Choose Moissanite?
Moissanite offers the beauty and presence of a diamond while providing exceptional value. It is durable, ethically created, visually stunning and suitable for everyday wear.
For those seeking timeless jewellery without the traditional diamond price tag, moissanite has become one of the most popular alternatives available today.
