1. Mistake: Confusing "Diamond Coated" with Genuine Moissanite

Many sellers use misleading terms like "Diamond Coated CZ." In reality, this is just Cubic Zirconia with a thin film. GIGAJEWE Truth: Genuine moissanite is Silicon Carbide (SiC), a mineral that naturally possesses its own fire and 9.25 hardness. Never settle for "coatings."

2. Mistake: Ignoring the "Cut Grade" (The Milky Look)

Most online shoppers focus only on Carat and Color. However, a poor cut is the #1 reason moissanite looks "milky" or "plastic." Our lab-grown stones undergo precision Hearts & Arrows cutting to ensure crisp light reflection that rivals natural diamonds.

3. Mistake: Believing All "D Color" Claims

Without proper quality control, some "D Color" moissanite can show a yellowish or grayish tint under sunlight. Always ensure your seller provides a Certificate of Authenticity. At GIGAJEWE, we strictly grade every stone against GIA standards.

4. Mistake: Overlooking the Warranty Policy

A gemstone is for life. If a seller doesn't offer a Lifetime Warranty on brilliance, it’s a red flag. High-quality moissanite will never lose its sparkle or turn cloudy. We back every GIGAJEWE stone with a permanent brilliance guarantee.

5. Mistake: Buying from "No-Review" Marketplaces

Social media ads often lead to "pop-up" shops. Check for third-party reviews and a clear About Us page that shows the brand's history and expertise in lab-grown gemstones.
