Moissanite Stones

Sparkling Moissanite – a brilliant, affordable diamond alternative.
Moissanite, from ₹2,100. All commercial moissanite is lab-created — that is why a stone this size costs a fraction of a diamond. It is silicon carbide, not diamond, and it disperses light more strongly, so it throws more coloured fire; some buyers love that, others prefer diamond's quieter sparkle. At Mohs 9.25 it is nearly as hard as diamond and stands up to daily wear in an engagement ring. Each stone comes with its grading report.

Moissanite Stones Buying & Gemological FAQs

Essential gemological facts, origin differences, heat treatments, laboratory certification, and traditional cultural customs.

What is Moissanite, and how is it created in gemological laboratories?

Moissanite is a laboratory-created crystalline gemstone composed of Silicon Carbide (SiC):

  • Natural Discovery vs. Laboratory Creation: Natural moissanite is extraordinarily rare in nature, originally discovered in microscopic crystal grains in 1893 by Nobel laureate Henri Moissan within the Canyon Diablo iron meteorite in Arizona. Because natural mineral deposits are far too small to fashion into gemstones, 100% of commercial gem-quality moissanite is synthesized in advanced high-temperature laboratory facilities using thermal sublimation processes.
  • Chemical & Optical Purity: Modern lab-grown moissanite achieves exceptional crystal purity, typically grading in the D-F colorless spectrum with VVS1 clarity. Explore complete comparative metrics in our Moissanite vs Diamond Guide.
How does Moissanite compare to Natural Diamond in hardness, brilliance, and fire?

While visually reminiscent of diamonds, moissanite possesses distinct gemological and physical attributes:

  • Hardness (Mohs Scale): Moissanite measures 9.25 on the Mohs scale, making it the second hardest gemstone used in modern jewelry. Only diamond (Mohs 10) is harder. It easily outperforms sapphire (Mohs 9), emerald (Mohs 7.5–8), and cubic zirconia (Mohs 8–8.5), resisting scratches, scuffs, and chips during daily wear.
  • Refractive Index & Brilliance: Moissanite has a refractive index of 2.65 to 2.69 (higher than Diamond’s 2.417), producing intense brilliance.
  • Dispersion (“Fire”): Moissanite has a dispersion rating of 0.104—more than 2.4 times that of natural diamond (0.044). Under direct sunlight, it throws dramatic, rainbow-colored flashes of spectral fire.
  • Specific Gravity: Moissanite has a specific gravity of 3.22, making it approximately 10% lighter than diamond (3.52).
How do gemologists distinguish Moissanite from Natural Diamond during laboratory testing?

Because moissanite has thermal conductivity close to diamond, basic thermal diamond pens will register a false positive (“diamond”). Professional gemologists separate them using diagnostic optical and electrical tests:

  • Birefringence / Double Refraction: Moissanite is doubly refractive (DR) with a high birefringence of +0.043. When viewed under 10x magnification at an oblique angle through the crown facets toward the culet, the facet junctions appear doubled. Diamonds are singly refractive (SR) and never exhibit facet doubling.
  • Electrical Conductivity Testers: Multi-testers evaluate electrical conductivity alongside thermal properties; moissanite conducts electricity slightly, instantly distinguishing it from natural non-conductive diamonds (Type Ia).
  • The Ratna Gems Disclosure: Every Moissanite stone at Ratna Gems is explicitly and transparently sold as Laboratory-Grown Moissanite (Silicon Carbide), accompanied by a laboratory testing report documenting dimensions, carat weight, color, clarity, and laboratory-created origin.

Optional International Certification: Every gemstone includes an independent accredited laboratory certificate at no charge. If you specifically require an additional report from GII, IIGJ, or IGI, you can select it directly from the certification dropdown on any product page upon request (official laboratory testing fees apply in advance on a non-refundable basis).

How durable is Moissanite, and how should it be cleaned and maintained in fine jewelry?

With a Mohs hardness of 9.25, exceptional thermal resistance (tolerating temperatures exceeding 1,100°C), and no directional cleavage sensitivity, Moissanite is one of the most durable gemstones for daily engagement rings:

  • Resistance to Clouding: Unlike porous substitutes or soft cubic zirconia (which absorbs oils, scratches easily, and turns milky over time), moissanite never fogs, clouds, or loses its brilliance over a lifetime of wear.
  • Jewelry Settings: Resilient enough for fine prong, pave, tension, and channel settings in 14K/18K Gold and Platinum.
  • Safe Cleaning: Moissanite can be safely cleaned using ultrasonic jewelry machines, warm water with mild dish soap, and a soft brush. Rinse thoroughly under warm running water and dry with a lint-free microfiber cloth.
Can Moissanite be worn as an astrological substitute (Upratna) for Diamond in Vedic Astrology?

In classical Vedic astrological traditions (Jyotish Shastra), gemstones must be natural, untreated, Earth-mined minerals formed over millions of years deep within the crust to be traditionally recommended for planetary remedies (such as Diamond for Venus/Shukra):

  • Traditional Perspective: Because moissanite is a modern synthetic laboratory-created material, classical Vedic literature does not prescribe it as an astrological remedy (Upratna). For traditional Venus astrological purposes, natural Earth-mined gems like White Sapphire (Safed Pukhraj), Natural Zircon (Jarkan), or Quartz Crystal (Sphatik) are traditionally selected.
  • Modern Jewelry Purpose: Moissanite is offered exclusively as an ethical, stunning, and affordable modern fine jewelry gemstone ideal for engagement rings, wedding bands, and daily luxury.
