What Are Lab-Grown Diamonds?Real diamonds, reimagined.

A lab-grown diamond is chemically, physically, and optically identical to a mined diamond. The only difference is origin — created in a lab in weeks, not the earth over billions of years.

The Short Answer

Yes — a lab-grown diamond is a real diamond. It is pure crystallized carbon with the same hardness, brilliance, and fire as a stone pulled from the earth, graded on the very same 4Cs by IGI and GIA. It is not a simulant like cubic zirconia or moissanite. At Amorati, we call them grown diamonds: real, conscious, and certified.

How They're Made

Two ways to grow a diamond

Both methods recreate the conditions of natural diamond formation — and both produce a real diamond, identical to one mined from the earth.

01

High Pressure High Temperature

HPHT mimics the way diamonds form deep in the earth, using extreme pressure and heat to crystallize carbon into a diamond. The original method — robust and brilliant.

02

Chemical Vapor Deposition

CVD builds a diamond layer by layer from a carbon-rich gas inside a vacuum chamber. Precise and efficient, it often yields stones with exceptional clarity.

The Amorati Standard
Lab-Grown vs. Mined

Same brilliance. Same forever. Less compromise.

Identical material — the differences are origin, footprint, and price.

Because you're not paying for rarity of origin, you'll often get higher clarity, better color, or a larger stone for the same budget.

Are lab-grown diamonds worth it?

For most modern buyers, yes. A grown diamond gives you the beauty and permanence of a real diamond — with greater transparency and more stone for your budget.

  • They're real. Same composition, same grading, same permanence as mined.
  • They're conscious. No mining, no mystery — just beauty with full transparency.
  • They're elevated. Often higher in clarity and color, without the markup.
  • They're modern. Made for how you live, love, and wear jewelry now.

Common Questions

Lab-grown diamond FAQs

Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are genuine diamonds made of pure crystallized carbon, with the same chemical, physical, and optical properties as mined diamonds. They are not simulants like cubic zirconia or moissanite.
Do lab-grown diamonds test as real diamonds?
Yes. Because they are made of carbon, lab-grown diamonds pass a standard diamond tester, which measures thermal and electrical conductivity. Distinguishing a grown diamond from a mined one requires specialized gemological equipment.
Will a lab-grown diamond get cloudy or lose its sparkle?
No. With a hardness of 10 on the Mohs scale — the same as a mined diamond — a lab-grown diamond will not cloud, dull, or scratch with normal wear. Its brilliance is permanent.
How much cheaper are lab-grown diamonds?
Lab-grown diamonds typically cost 30–60% less than a comparable mined diamond of the same carat, cut, color, and clarity. That value lets many buyers choose higher clarity, better color, or a larger stone for the same budget.
Can a jeweler tell the difference between lab-grown and mined diamonds?
Not by eye. A lab-grown diamond is visually identical to a mined diamond. The origin can only be determined with specialized equipment, and certified stones are laser-inscribed with their report number.
How long do lab-grown diamonds last?
Forever. A lab-grown diamond has the same durability and permanence as a mined diamond, making it ideal for engagement rings and everyday fine jewelry meant to last a lifetime.
Are Amorati's diamonds certified?
Yes. Every Amorati center diamond is independently IGI-certified and set in solid 14K or 18K gold — never plated.

Find the one worth remembering.

Whether you're choosing your first piece or marking a forever moment, grown diamonds offer a new kind of luxury — one that reflects your values as much as your style.
