A Clear Comparison by AFSA

At AFSA, we believe every customer deserves clarity when choosing a gemstone that reflects their story. Whether you’re drawn to the timeless prestige of a mined diamond or the modern brilliance of moissanite, understanding the differences helps you make a confident, meaningful choice.

Origin & Creation

Moissanite

• • Originally discovered in a meteor crater, moissanite is composed of silicon carbide.

  • Natural moissanite is extremely rare, so all moissanite used in jewelry today is lab‑grown, created ethically and sustainably.

  • Has a higher refractive index than diamonds, giving it even more sparkle—often with a rainbow‑like fire.
  • Extremely durable with a Mohs hardness of 9.25, suitable for everyday wear.
  • Lab‑grown, conflict‑free, and environmentally responsible—ideal for conscious buyers.
  • Offers exceptional beauty at a significantly more accessible price point.

Mined Diamond

• • • Formed naturally over billions of years deep within the Earth under intense heat and pressure.

    • Extracted through mining operations, which can involve environmental and ethical concern.

    • Known for its classic, crisp white brilliance, admired for generations.
    • The hardest natural material on Earth, scoring a perfect 10 on the Mohs scale.
    • Graded on the traditional 4Cs (color, clarity, cut, carat), with natural variations in each stone.
    • Mining can involve land disruption, water usage, and in some regions, human rights concerns.
