How Are Lab GrownDiamonds Made
2
  • 1. Inspect Diamond Seeds
  • Each seed is made of a repeating lattice of
    carbon atoms - just like natural diamonds. Its
    carefully evaluated to ensure they are free of
    inclusions.

3
  • 2. Plant the seeds on Disk
  • Prepare the surface for growth and place diamond
    seeds on metal disk- usually containing 15-30
    diamond seeds.

4
  • 3. Placed in the Chamber
  • Inject carbon-rich gases in chamber and excite
    the gases to an energy level where they form a
    plasma.

5
  • 4. Super High Temperature
  • Control chamber pressure and temperature is
    increased to 900-12000 C.

6
  • 5. Let it Grow
  • The activated carbon-hydrogen species attaches
    itself to the seed atom.

7
  • 6. See in Action
  • This process repeats itself endlessly for 3-4
    weeks to replicate the crystal structure of the
    diamond seed in three dimensions.

8
  • 7. Tightly Monitored
  • The moment where seed crystal reach the desired
    diamond characteristics, quick removal alert has
    been set to the technician.

9
  • 8. Ready to Cut Polish
  • Rough diamonds are removed from the chamber and
    cut and polish into gems.
