it looks really really good. i'm super torn between their new radiant and the elongated cushion, not sure which fits my finger better, ive been around looking for fancies but nothing even comes close to jannpauls cuts
they all look leaky mushy dull
it's not only their cuts, labgrown cvd or hpht goes from **** quality to the highest. So much low quality lab grown sellers, even chain stores or the so called "lab grown" speciality jewelers all sell very low quality labgrown
materials. if ure using as engagement ring go to JP cause their lab grown quality is guaranteed on their site:
White Series (Lab Grown Diamonds)
The White Series range is available in Lab Grown Diamonds. All of our lab grown diamonds are slow growth (no catalyst is used), using the top quality carbon seeds. Over 99% of lab grown diamonds suffers from Stria issues, causing birefringence in the diamond, which is viewable under polarized lights. In addition, many growers uses inferior catalyst or re-use carbon seeds, causing unnatural off hues (Eg. Brown, blue or metallic gray) in the diamond. In JANNPAUL, all of our lab grown diamonds are guaranteed to be free from stria or off hues. Our diamonds are all Type IIa, the chemically purest makes and are AGS or GIA certified only. We do not carry IGI certified diamonds for various reasons.
Due to our strict and slow growth methods, most of our lab grown diamonds are sold out. However, we do accept custom orders, and able to grow and cut a diamond in your preference. We sincerely apologize for our lack of stock. Our lab grown diamonds are available in D-F Colors, VVS1-VS1 Clarity.
Our Quality (Lab Grown Diamonds)
Our Lab Grown diamond quality follows the same criteria as our Natural Earth Mined Diamond as mentioned above, with the following additional points:
AGS or GIA Certified only (strictly no IGI certificate)
All Type IIa only
No Stria issues (commonly found in Lab Grown diamonds)
No birefringence
No unnatural metallic or blueish hue
No brownish or off color hue
No fluorescence
In the lab Grown Diamond industry, majority of growers try to grow as many diamonds as possible at the shortest duration. The common trend is to grow as much as possible at the lowest cost and time. However, this has led to unnatural looking lab grown diamonds with birefringence and stria issues (viewable under polarized lights), and off-color hues. In our growing process, we ensure all of our lab grown diamonds are grown in the purest chemical form and adopt an ethically responsible process.
We use the highest quality carbon seeds
We never reuse our carbon seeds
We do not add catalysts (eg. Boron) to speed up the growth process
Our chambers are contaminant free
Constant electricity supply (no restart during growth process)
Our Lab Grown Diamonds are from the same grower to ensure quality and ethical practices
TLDR: if you don't follow pricescope:
HPHT: very common to have blue / metallic nuance, greyish. this is because of poor use of seeds or too much boron, or nitrogen. the only way to guarantee it has luster is for HPHT to go through lab testing for type IIA. which is damn rare
and jannpaul seems like the only one in the world who can produce them and is tested iia in gcal.
CVD: this one is much much more problematic, and irl if u know what ure looking for, i've been around many different lab grown shops, if they set in ring which has a open crown turn the ring upside down and look at the body color,
most shops you'll see very very common brownish tint.(on pricescope i've seen other off hue like green grey pink brown etc, but Singapore tends to be always brown or grey from what ive seen from most shops)
striation: vary from shop to shop depends on the lighting. some shops its very easy to see cause they use LED you can see alot of straining lines, and this heavily affects fire(refraction) and the diamond appears fuzzy
The most dangerous is this: phosphorescence, i dont see much people talking about this at all, low quality cvd that exhibits phosphorescence can cause the diamond to change color over time if exposed years to sunlight, idk why no one
ever talks about this. bring a uv torch if u have one, if it glows, then forget about it.
if you're looking for quality guaranteed go to JP, not only does the cut matter, but the material of the lab grown is equally as important if you really want a beautiful rock
im a chem engineer, theres so many lab grown companies in Singapore who don't know a thing, all they talk about it is it's more "ethical".
