Which is better moissanite or lab-created diamonds?

May 29, 2024

Selecting an exquisite gem to adorn your next piece of jewelry may seem intimidating, but two ethically sourced and stunning alternatives to mined diamonds: moissanite and lab-grown diamonds shining bright, offer exceptional brilliance and fire. But, which is better moissanite or lab-created diamonds?

Pompeii3 takes great pleasure in helping our customers find jewelry they truly adore; our guide equips you to make an informed choice between moissanite and lab-grown diamonds.

The Beauty of Moissanite

Moissanite, first discovered during the 19th century, can now also be produced artificially in labs. Made up of silicon carbide crystals, its stunning brilliance features rainbow flashes of light that lend it an irresistibly unique hue - which may otherwise remain out of reach to some consumers. Although rare naturally, lab-created moissanite offers greater accessibility.

Laboratory Grown Diamonds

Lab-grown diamonds are not fake replicas - they contain real carbon just like mined gems do and share similar physical and chemical properties. Utilizing cutting-edge technology, scientists recreate extreme pressure and heat conditions deep beneath the Earth to accelerate natural diamond formation processes faster, creating stunning gems that look virtually indistinguishable from mined counterparts.

Understanding Key Differences - Lab Grown vs Mined Diamonds

Let's now examine some key distinctions that distinguish moissanite from lab-grown diamonds:

  • Appearance: Moissanite boasts exceptional brilliance with its signature rainbow brilliance while synthetic gems often offer more classic diamond sparkle with white light plays that some find timeless.
  • Durability: Both gems boast impressive hardness, making them suitable for everyday wear. Moissanite ranks 9.25 on the Mohs mineral hardness scale while lab-grown diamonds boast an ideal 10 rating in hardness index rating.
  • Price: Moissanite offers more value for your dollar when considering purchasing standout stones like moissanite than synthetic gemstones do, making it the more cost-effective solution when seeking to expand their jewelry box with one.
  • Ethics and Sustainability: Moissanite gems produced without conflict have less of an environmental footprint compared to mined stones, thus being an ethical choice that benefits society as a whole.
