Choosing an engagement ring is among the most significant decisions couples make. Diamonds have been the hallmark of commitment, embodying love, luxury, and timeless elegance. Recently, however, moissanite has come out as a diamond alternative, but is it truly comparable? At Carat Sage, we believe that while moissanite might be tempting due to its lower price, it does not match the unmatched beauty and lasting value of genuine diamonds. We exclusively offer premium-quality diamond jewellery crafted to celebrate your most special moments.

 

What Exactly Are Moissanite and Diamonds?

Moissanite

A Lab-Created Substitute Moissanite is a synthetic gemstone made from silicon carbide. Originally discovered in trace amounts from meteorites, today’s moissanite is almost entirely lab-grown, manufactured to mimic the brilliance of diamonds. Despite its initial appeal, moissanite falls short in various aspects, especially when compared directly to diamonds.

Diamonds

Nature's True Masterpiece Diamonds are natural gems, formed deep within the Earth under extreme heat and pressure over billions of years. Their rarity, purity, and inherent value set diamonds apart, making them ideal for meaningful, lifelong investments and cherished heirlooms.

 

Key Differences Between Moissanite and Diamonds

1. Visual Brilliance Moissanite

 Although moissanite is known for its excessive sparkle, it often produces an overly bright, rainbow-like effect. This artificial-looking sparkle can appear unnatural and less refined compared to the understated brilliance of diamonds.

Diamonds: Diamonds offer sophisticated, balanced brilliance. Their classic sparkle is unmatched, reflecting a purity and elegance that cannot be artificially replicated.

2. Durability and Longevity Moissanite

With a hardness rating of 9.25 on the Mohs scale, moissanite may seem robust but still falls short of diamonds. Over extended periods, its surface can sustain visible wear or scratches.

Diamonds: Diamonds rank a perfect 10 on the Mohs scale, the hardest known material. They withstand daily wear exceptionally well, remaining pristine through generations of use.

3. Colour and Clarity Moissanite

Despite claims of near-colourlessness, moissanite often reveals subtle yellow or grey tints under natural lighting, detracting from its overall appearance.

Diamonds: Diamonds are meticulously graded, from perfectly colourless (D grade) to noticeable colour tints (Z grade). Premium diamond selections ensure consistent clarity and purity, enhancing their timeless appeal.

No, diamonds are superior in durability, capable of maintaining their pristine condition much longer due to their unmatched hardness.
