Moissanite – The Gemstone Born from the Stars

It is a distinct mineral with a unique origin, modern production methods, and exceptional optical properties.

Today, moissanite is increasingly recognized as a durable and responsible alternative in fine jewelry — valued for performance rather than symbolism.

A Fragment from the Stars

Moissanite was first identified in 1893 by the French chemist Henri Moissan in a meteorite crater. The crystal fragments were initially mistaken for diamonds before being identified as a separate mineral: silicon carbide (SiC).

Due to its extreme rarity in nature, moissanite is now grown exclusively in advanced laboratory environments. This allows for controlled quality, high purity, and consistent optical performance.

Moissanite is often compared to diamond because both stones appear similar to the naked eye. Subtle differences, however, can be identified through technical examination and optical behavior.

Optical Performance and Material Properties

Moissanite is a gemstone in its own category, defined by distinct physical characteristics.

• Refractive index: approximately 2.65–2.69 (higher than diamond at 2.42)

• Fire: strong colored light dispersion due to double refraction

• Brilliance: high light return with vivid sparkle

• Hardness: 9.25 on the Mohs scale (diamond: 10)

Thanks to its hardness and crystal structure, moissanite is highly resistant to scratching and does not lose clarity over time — unlike some diamond simulants such as cubic zirconia.

Clarity and Color Standards

High-quality moissanites are produced with exceptional consistency.

At Glacier & Aurealis, moissanites are selected with:

• VVS1 clarity (very, very small inclusions)

• D color grade (colorless)

• excellent cut quality for balanced light performance

Diamonds with comparable clarity and color exist, but they are significantly rarer and typically associated with higher costs.

Sustainability and Responsible Origin

Unlike mined diamonds, moissanite is created without large-scale excavation or environmental disruption.

Laboratory growth:

• avoids destructive mining

• eliminates concerns related to forced labor

• requires fewer natural resources

Moissanite offers a transparent and responsible material origin suited to modern fine jewelry.

The Glacier & Aurealis Perspective

At Glacier & Aurealis, moissanite is chosen deliberately — not as an imitation, but as a gemstone defined by clarity, durability, and consistent performance.

Material selection focuses on:

• long-term wearability

• optical stability

• refined aesthetics aligned with modern fine jewelry

Understanding the material is the foundation of confident, informed choice.

A Clear Distinction

Moissanite is not positioned as a replacement for diamonds.
It represents a different category — shaped by science, performance, and intention.

Recognizing that distinction allows for clarity without compromise.
