I heard a rumor that JannPaul was growing its own diamonds. I asked my JP SA about this and was surprised and honored when Paul himself answered. Here is what he told me:
Paul here, yes we've got our own lab, the process is patented, but we have yet to officially announce a full launch. we are currently in collab with gcal8x for the white series lab growns and it'll be probably a collaboration PR launch as it'll be a gcal8x premium cert, we/they havent decided on it's name. the reason for the different classification is because all the white series diamonds surpass their metrics on the 8x, so they need to create a whole new 8x type cert so there is no confusion to the normal fancy shape cuts.
with regards to our lab grown diamonds yup!
the growth process is 2 methods, creating a true type iia hthp by gcal's and ags standards. (not igi's iia standards). blue nuance or anything else "unnatural" like grey hue and or unnatural looking inclusions is entirely removed. the growth process is nothing secret to the industry but the recipe is.
2nd process is using microwave plasma cvd in combination with hpht - the growth process here and recipe is both a secret because the recipe is within the grown process and patented. a true type iia without any off hue (commonly brown) nor striation can be created. using mpcvd + hpht isn't anything new, but during the growth process, temperation gas amount levels, starting seed quality, no stoppage to remove carbon substrates etc all are just some factors within.
we've already been selling them via word of mouth just that we'd like to wait for gcal 8x to finalize everything to officially launch them.
in a nutshell, yes i can confirm this is the pinnacle of what every lab grower is trying to achieve. research has been 4 years long.
i've just finished the recipe to creating true blue's as well with no grey or green undertones, the colored diamonds are actually the most difficult. true yellows are easy, and currently, i'm in the midst of pinks. which is every grower's nightmare. orangey pink, brownish pink, is all over the market. i'm close to creating a true pink. it's much more complex than the other colors as the recipe requires quite a few steps, and each step has no error for miscalculation. i've already managed to produce them quite consistently, (by disrupting and shifting the crystal lattice and shifting the nitrogen to create NV centres), but theres maybe 50 percent rejection in terms of the consistency to finalize.
