Moissanite: The Brilliant Star

Why Moissanite Shines:

  • Sparkle Factor: Moissanite boasts more fire and brilliance than diamonds, making it incredibly eye-catching.

  • Durability: With a Mohs hardness of 9.25, it’s highly resistant to scratches, perfect for everyday wear.

  • Eco-Friendly: Lab-created moissanite has a minimal environmental footprint, making it a green choice.

  • Affordability: Enjoy the luxury look of a diamond without breaking the bank. Moissanite is much more budget-friendly.

Diamond: The Timeless Classic

Why Diamonds Endure:

  • Unmatched Durability: Diamonds top the Mohs scale with a hardness of 10, making them the most durable gemstone.

  • Brilliance and Fire: While slightly less fiery than moissanite, diamonds are known for their stunning brilliance.

  • Symbol of Forever: Diamonds have long been associated with enduring love and commitment.

  • Investment Value: Diamonds hold their value well over time, making them a good investment.

Cubic Zirconia: The Affordable Sparkle

Why Not Choose Cubic Zirconia?

  • Lower Durability: With a Mohs hardness of 8-8.5, cubic zirconia is more prone to scratching and damage, making it less suitable for everyday wear.

  • Less Brilliance: Cubic zirconia lacks the fire and brilliance of moissanite and diamonds, giving it a less dazzling appearance.

  • Fades Over Time: Unlike diamonds and moissanite, cubic zirconia can become cloudy and lose its sparkle with prolonged use.

  • Perceived Value: While cost-effective, cubic zirconia doesn’t hold the same prestige or perceived value as diamonds or moissanite, making it less desirable for significant jewelry pieces like engagement rings.
