Lab-Grown Diamonds vs. Natural Diamonds

One of the most popular discussions within the world of jewelry today is the difference between lab-grown diamonds and natural diamonds. 

The difference is that lab-grown diamonds are made in a laboratory instead of inside the earth. 

That difference in origin is also what makes lab-grown diamonds typically 60%-70% less expensive than natural diamonds.

Both are beautiful options, and choosing between them is simply a personal choice.

Did You Know?

Lab-grown diamonds are optically, chemically and physically identical to the naked eye.

Both are the same in so many ways:

  • One-of-a-kind with unique internal characteristics
  • Cut and faceted from rough diamond material
  • Identical in scintillation (sparkle) and fire with a 2.42 refractive index and dispersion of .044
  • Available in a range of qualities and fancy colors
  • Made of pure carbon with a hardness rating of 10
  • Graded using the same universal standards of carat, cut, color and clarity.

They differ in their origin and cost

Lab-Grown Diamonds

  • Grown in 4 weeks in laboratories overseas
  • Supply available on demand (not rare)
  • Production cost extremely low and lowering each month
  • Uncertain Future Value (Not Eligible for Trade Up Program)

Natural Diamonds

  • Created over millions to billions of years within the earth
  • Finite Supply (rare)
  • Valuable material, stable/increasing prices
  • Holds Value (Lifetime Trade Up Program)

How can you tell the difference between them?

Since lab-grown diamonds are optically, chemically, and physically identical to natural diamonds, you can’t tell the difference between them with your naked eye.

There are lab grown testers available to differentiate a diamonds origin. Also, a trained gemologist can differentiate natural vs synthetic characteristic inclusions.

How are Lab-Grown Diamonds made?

Two different methods are used, sometimes together, to create lab-grown diamonds. 

  • High Pressure High Temperature (HPHT) 
    This process mimics mother nature by applying high pressure and high heat inside specialized equipment to a diamond seed, accelerating the growth of crystalized diamond. 
  • Chemical Vapor Deposition (CVD) 
    This process uses a chemical vapor-based method to stimulate growth of crystalized diamond from a diamond seed.


All of our in stock jewelry is made with natural diamonds. Lab grown diamonds are available by special order only.
