What you send
You only send a small sample. No special handling is needed beyond safe, clean packaging.
-
Ashes: typically 25–50g, clean, dry, sealed.
-
Hair: typically 1–2g, clean, dry, sealed. You can send hair in a labeled zip-lock bag inside an envelope or small box.
Privacy and respect Your sample is processed under a unique batch ID and handled with strict labeling inside our workflow.

Step-by-step process
1) Sample received and logged
We receive your sealed package, assign a unique batch ID, and perform initial checks.
2) Purity and contamination check
Moisture and impurities are evaluated to improve carbon recovery and growth stability.
3) Carbon extraction and purification
Carbon is separated and cleaned through controlled purification steps.
4) Diamond seed preparation
A diamond seed plate is cleaned and prepared as the base for your diamond.
5) CVD diamond growth
In a high-vacuum chamber, carbon atoms deposit layer-by-layer to form a real diamond crystal.
6) Cut, polish, and symmetry
The rough diamond is mapped, cut, faceted, and polished to your chosen shape.
7) Quality check
We review cut, polish, symmetry, and finishing before certification and packaging.
8) Certificate and verification
You receive a Brand Authenticity Certificate with diamond ID and online verification.
9) Jewelry setting and delivery
Choose loose diamond or jewelry. We package securely and ship with tracking.
Updates and documentation We provide milestone updates by email. If you prefer WhatsApp milestone updates, request it after purchase and our team will assist.
CVD vs HPHT for memory diamonds
Both methods create real lab-grown diamonds. For memorial diamonds, we primarily use CVD because it offers controlled layer growth, strong consistency, and efficient production for custom orders.
| Factor |
CVD (Our primary method) |
HPHT (Alternative method) |
| How it grows |
Layer-by-layer growth in a vacuum chamber using process gases. |
High pressure + high temperature growth in a press. |
| Control and consistency |
Excellent control over growth conditions; ideal for repeatable custom runs. |
Strong results possible, but the process is more equipment-intensive. |
| Typical lead time |
Often efficient for custom orders; depends on size and jewelry complexity. |
Can be longer due to press scheduling and production constraints. |
| Cost efficiency |
Often more cost-efficient for made-to-order memorial projects. |
Usually higher production cost due to press operation and tooling. |
| Why we prefer it |
Best balance of quality control, scalability, and pricing for memory diamonds. |
Works well in certain cases, but not our default workflow for memorial orders. |
Certification and proof
You will receive a Brand Authenticity Certificate including diamond ID and batch ID, source type (hair or ashes; pet or human), diamond details, and verification instructions.
-
Online verification: enter your unique ID on our verification page.
-
Optional third-party grading: IGI can be added by request and may require extra cost and time.
Important transparency Due to scientific and technical limitations, 100% of the diamond’s carbon content may not originate solely from the submitted remains. The diamond is grown using carbon derived from the submitted hair/ashes as part of the process.
Choose your final piece
You can choose a loose diamond or complete jewelry.
- Loose memory diamond
-
Rings (solitaire, halo, bezel, 4-prong, 6-prong)
-
Pendants (classic, heart, halo, bezel)
-
Earrings (studs, bezel studs, halo studs)
-
Bracelets (tennis or bezel styles)
Estimated timeline
Timeline varies by carat size, shape, and jewelry complexity. A typical flow includes:
- Sample received and logged
- Carbon purification
- CVD growth (commonly 20–45 days depending on target size)
- Cutting and polishing
- Setting (if jewelry)
- Secure shipping with tracking
FAQ
Do you return unused hair or ashes?
Our standard process does not return unused materials because samples are used within controlled lab handling and purification steps. If you have a special request, contact us before sending your sample.
How do I get updates?
We send milestone updates to the email used at checkout. After purchase, you can request WhatsApp milestone updates as well.
What if I do not receive my purchase after payment?
Every order ships with tracking. If there is an unexpected delay or shipping exception, our support team will assist until delivery or propose a fair resolution based on the order stage and store policy.

Certificate Verification: BJ-ABCZXY001
Legal and compliance notice (USA, Canada, Global)
Truthful marketing: Black Jack® Memory diamonds are real lab-grown diamonds. We do not claim “natural mined” origin.
Transparency: Due to technical limits, 100% of the diamond’s carbon may not come solely from the submitted remains; carbon from the submitted remains is used as part of the process.
Not forensic identification: This product is a memorial keepsake and is not a legal identity or forensic document.
Certification: Brand Authenticity Certificate + verification method. Third-party grading (such as IGI) is optional and available by request with additional time and cost.
Custom product policy: Because each order is custom-made, changes/cancellations may be limited once production has begun. Please review the store’s current policy for exact terms.
Local laws: Buyers are responsible for complying with local shipping/import rules. We provide documentation and tracking to support delivery where possible.
