Understanding the Gemstones

• Moissanite: A lab-created gemstone made of silicon carbide, discovered in 1893 by Henri Moissan. Known for its fiery sparkle and durability, it’s a popular diamond alternative.
• Lab-Grown Diamond: A real diamond grown in a lab using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD), chemically identical to mined diamonds.
• Cubic Zirconia (CZ): A synthetic gem made of zirconium dioxide, widely used as a budget-friendly diamond simulant.

• Moissanite: Highly affordable, costing $300-$800 for a 1-carat stone, about 10-20% of a natural diamond’s price.
• Lab-Grown Diamond: More expensive than moissanite but 20-40% cheaper than natural diamonds, with 1-carat stones ranging from $1,500-$3,000.

2. Brilliance: Sparkle Factor

• Moissanite: Boasts a higher refractive index (2.65-2.69) than diamonds, creating intense rainbow flashes and fiery sparkle, especially in sunlight.
• Lab-Grown Diamond: Matches natural diamonds with a refractive index of 2.42, offering balanced white and rainbow sparkle, considered classic.
• CZ: Has a refractive index of 2.15-2.18, providing decent sparkle but less fire than moissanite or diamonds. May look glassy in some lights.
  Why It Matters: Moissanite shines brightest, lab-grown diamonds offer traditional sparkle, and CZ is less vibrant but still eye-catching.
  Best For: Moissanite for bold sparkle, lab-grown diamonds for classic elegance, CZ for subtle shine.
