The Complete Guide
Moissanite vs Lab-Grown Diamond vs Natural Diamond
Choosing the right stone is one of the most important decisions in your jewellery journey. Here is everything you need to know — side by side — so you can choose with confidence.

Earth-Mined, Billions of Years Old
Learn About Each Stone
What is Moissanite?
Moissanite is a lab-created gemstone made of silicon carbide, first discovered in a meteorite crater by Nobel Prize winner Henri Moissan in 1893. It is one of the rarest minerals found in nature, which is why today it is grown in controlled laboratory environments.
With a refractive index of 2.65–2.96, moissanite has more brilliance and fire than a diamond — meaning it produces more rainbow-coloured sparkle in light. It scores 9.25–9.50 on the Mohs scale, making it the second hardest gemstone in the world and perfect for everyday wear.
Moissanite offers maximum size and sparkle at a fraction of the cost of a natural diamond — making it the ideal choice for budget-conscious buyers who refuse to compromise on beauty.
What is Lab Grown Diamond?
Lab-grown diamonds are real diamonds — chemically, physically, and optically identical to natural earth-mined diamonds. They are created in highly controlled laboratory environments using two methods: High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD), replicating the natural diamond-growing process.
Because lab-grown diamonds are the same material as natural diamonds, they carry the same hardness (10 on the Mohs scale), the same refractive index (2.42), and can be certified by the same grading laboratories — IGI and GIA. Even trained gemologists cannot distinguish them with the naked eye.
Lab-grown diamonds are the perfect choice for eco-conscious buyers who want a real diamond at 40–60% less than the price of a mined stone.
What is a Natural Diamond?
Natural diamonds are formed deep within the earth's mantle over billions of years under extreme heat and pressure, then brought to the surface through volcanic activity. Each natural diamond is a unique, one-of-a-kind creation of the earth — no two are exactly alike.
Diamonds are the hardest known natural material, scoring 10 on the Mohs scale. Their timeless brilliance and rarity have made them the ultimate symbol of love and commitment for centuries. Natural diamonds are graded on the 4Cs — Cut, Colour, Clarity, and Carat — by internationally recognised laboratories such as GIA and IGI.
For buyers seeking a traditional investment piece or a timeless heirloom with natural provenance, a natural diamond remains without equal.

Frequently Asked Questions
A lab-grown diamond is a real diamond produced in a controlled laboratory environment rather than mined from the earth. It shares the exact same chemical composition, crystal structure, and physical properties as a natural diamond, meaning it is just as hard, brilliant, and durable. Because it requires no mining, it offers an eco-conscious and conflict-free choice without any compromise on beauty or quality.
Moissanite is a gemstone made of silicon carbide, prized for its exceptional brilliance, fire, and durability. Originally found in a meteorite, it is now created in laboratories for use in fine jewelry. Its remarkable hardness and heat resistance, paired with its affordability and ethical production, have made it one of the most popular diamond alternatives available today.
Yes. Our lab-grown diamonds are certified by trusted gemological laboratories such as IGI or GIA, verifying their quality and authenticity. Our moissanite stones include a certificate of authenticity that confirms their premium grade. These certifications give you confidence in the ethical sourcing and craftsmanship behind every gemstone you purchase from us.
While both are stunning, they have distinct optical differences. Lab-grown diamonds display the classic white brilliance and luster of a natural diamond, whereas moissanite produces noticeably more colorful flashes of light, or "fire." Lab-grown diamonds also retain their clarity and sparkle permanently, while moissanite holds its own beauty with a slightly different character of shine.
Both gemstones are made to last a lifetime. Lab-grown diamonds rank a perfect 10 on the Mohs hardness scale, identical to natural diamonds, making them extremely scratch-resistant. Moissanite ranks 9.25, making it the second-hardest gemstone used in jewelry. With basic care, either stone will keep its brilliance and beauty for generations.
Moissanite is generally the more budget-friendly option, often costing significantly less than a comparable lab-grown diamond of the same size. Lab-grown diamonds, while more affordable than mined diamonds, sit at a higher price point because they are chemically identical to natural diamonds. Your ideal choice depends on your budget and what matters most to you in a stone.
It truly comes down to personal preference. Both are beautiful, ethical, and durable in their own right. If you want a stone chemically identical to a mined diamond, a lab-grown diamond is ideal. If maximum sparkle and value for money are your priorities, moissanite is an excellent choice. Ultimately, the best decision is the one that aligns with your style, values, and budget.
