Standards & Transparency
Transparency
With RisenGem, you will always know where your loved one's memorial diamond is in process. We are headquartered in Zhengzhou, Henan, China, with our own memorial-diamond research laboratory and growth workflows anchored in the province's advanced lab-grown diamond industry. Unlike providers who obscure where work happens, we set strict transparency protocols so you can see how each stage is completed and documented.

NGTC (国家珠宝玉石质量监督检验中心) is China’s flagship national jewelry and gemstone testing organization. It represents the same tier of consumer protection and industry oversight many Chinese families rely on when grading and authenticating diamonds and jewelry. We reference NGTC to show how your memorial diamond sits in a serious national quality ecosystem—not as a substitute for GIA or other reports we still provide where promised in your order.
NGTC branding shown for informational context; specific certificates for your diamond follow what is written in your order confirmation and laboratory documents.
Our Henan laboratory can welcome scheduled visits when travel and safety rules allow—because transparency should extend beyond the screen. Together with milestone updates and trace pages, we aim to offer what few memorial brands can: a chain of custody you can understand and, when possible, witness.

While elemental carbon burns off during cremation, there is still sufficient carbon found in the bone matter in ashes to be able to extract and grow multiple diamonds. If you have any concerns or simply love science, we can do a Total Carbon Analysis of your loved one's ashes upon request. RisenGem is the only memorial diamond company to offer third-party testing of ashes through accredited analytical chemistry labs.

RisenGem is not the cheapest or fastest — for good reason. We craft the highest quality memorial diamonds with precision and care.
Get StartedWhile the majority of our diamonds are in the VS range, we guarantee a minimum of SI2 clarity or better. If we don't meet our standards, we grow you a second diamond — and this time, it's on us. RisenGem is the only memorial diamond company with quality guarantees.

We always request more than enough material so we have extra carbon leftover that we will store on your behalf. That way, if ever you or family members want to have additional diamonds made, or your diamond is lost — we have additional carbon we've safely and securely stored for you.
