What is the HPHT Process?

High-pressure-high-temperature (HPHT) is one of
the two main methods used to create lab grown
diamonds. HPHT allows diamonds to grow from 14
different directions just as a natural diamond would.

Goodmark
Diamond Creation

step 1:

The HPHT diamond formation process begins
with a small diamond seed (a thin layer cut from
a natural diamond) that is placed into pure carbon.

step 2:

The diamond seed is exposed to intense
pressure (up to 70,000 atmospheric pressures)
and heat (more than 1,300° C).

step 3:

The carbon melts and a diamond
begins to form around the seed.

step 4:

The substance is carefully cooled to fully form.

step 5:

The diamond is then ready to be cut,
polished, and set into jewelry.

What is the
Recrystallization Process?

The recrystallization process is used
for goodmark’s colored gemstones including
Alexandrite, Emerald, Ruby, and Blue Sapphire.
No oil, gas, or color is used in the process
of making goodmark gemstones.

step 4:

We use a hot solvent to dissolve
any remaining imperfections (inclusions),
further purifying the gemstone seed.

step 5:

As the solvent cools, it recrystallizes
to form a flawless solid gemstone.
