LAB-GROWN DIAMONDS VS NATURAL DIAMONDS

Lab-grown and natural diamonds are chemically, physically, and optically identical, both are pure carbon with 10 hardness and the same brilliance. The key differences lie in origin, cost, and sourcing.

  • Identical properties: Same chemical composition, hardness, brilliance, and fire, professional jewellers cannot distinguish them without specialised equipment
  • Cost difference: Lab-grown diamonds cost less than natural equivalents, allowing larger stones or premium settings within budget
  • Origin and age: Natural diamonds formed billions of years ago underground, lab-grown created in weeks using HPHT or CVD technology
  • Ethical sourcing: Lab-grown diamonds are 100% conflict-free with transparent supply chains, while natural diamond sourcing can vary

Read our complete comparison of lab-grown vs natural diamonds for engagement rings

LAB-GROWN DIAMOND VS MOISSANITE ENGAGEMENT RINGS

Both lab-grown diamonds and moissanite create stunning engagement rings with ethical sourcing, but offer different benefits. Lab-grown diamonds provide authentic diamond properties and classic brilliance, while moissanite offers maximum sparkle with distinctive rainbow fire.

  • Authenticity: Lab-grown diamonds are identical to natural diamonds (hardness 10, classic brilliance), moissanite is its own gemstone (hardness 9.25, rainbow sparkle)
  • Visual differences: Lab-grown diamonds have classic white brilliance, moissanite displays more colourful "fire" and rainbow flashes
  • Choose lab-grown for: Authentic diamond experience with traditional elegance and cultural significance
  • Choose moissanite for: Maximum value and distinctive extra sparkle with unique brilliance

ARE LAB-GROWN DIAMONDS REAL DIAMONDS?

Yes, lab-grown diamonds are 100% real diamonds with identical chemical composition (pure carbon), physical properties (10 hardness), and optical characteristics to natural diamonds. The Federal Trade Commission and Gemological Institute of America recognise lab-grown diamonds as genuine diamonds.

  • Identical properties: Same hardness, brilliance, fire, and scintillation as natural diamonds, professional jewellers cannot tell them apart without specialised equipment
  • Same grading standards: Graded using identical 4 C's (cut, colour, clarity, carat) and certified by the same gemological institutes
  • Only difference is origin: Natural diamonds formed billions of years ago underground, lab-grown diamonds created in controlled laboratory conditions using HPHT or CVD methods
  • For engagement rings: Authentic diamond experience with identical beauty, durability, and cultural significance at a large cost savings
