How To Start
Step One
Share Your Vision & Receive a Quote
Tell us what you’ re looking for. To provide an accurate quote, we’ ll need the following:
1. Desired shape and cut style
2. Size ratio (e.g., length vs. width)
3. Approximate carat weight
4. Preferred color and clarity
5. A sketch or reference image, if available
Please note: Due to the unique nature of custom-cut diamonds, certain trade-offs may be necessary. For example:
· If you request specific measurements (e.g., 9.5 × 6.5 mm), pricing will be based on size—not carat weight—and the final carat may vary.
· If both carat and proportions are fixed, face-up size is determined by their relationship and cannot be customized separately.
· D–E color or VVS clarity requirements may be limited or result in higher costs.
Our experts will evaluate your request and walk you through the best options available.
Step Two
Confirm Your Order
Once you' re happy with the quote and details, we’ ll confirm the order and proceed with payment.
Step Three
The Cutting Process Begins
If no re-cutting is needed, this stage typically takes about two weeks. The full process includes:
1. Rough stone selection (usually three candidates)
2. Machine inspection for clarity and weight estimates
3. If unsuitable, new roughs will be sourced or selected from existing stones
4. Cutting begins once a suitable rough is confirmed
5. Post-cutting evaluation of color and measurements
6. If the result doesn' t meet your expectations, we start again with a new stone
Due to the complex and highly professional nature of this process, we won’ t provide step-by-step updates. However, rest assured—once cutting is complete, we’ll send you a video for your review.
Stpe Four
Video Review & Final Confirmation
We’ ll send a high-quality video of the finished diamond so you can confirm everything before certification.
Step Five
Grading & Certification
Your diamond will be sent to your chosen grading lab. Available options:
Lab | Language | Fee | Timeline |
| IGI | English | Base on Carat | ~4 weeks |
| GIL | English | $100 flat rate | ~1 week |
| GRC | English | $50 flat rate | ~1 week |
We recommend choosing a lab based on your timeline and budget.
Step Six
Certificate Confirmation
Once grading is complete, we’ ll send you a photo of the certificate for your records.
Stpe Seven
Secure Shipping
If you don’ t require custom jewelry, we’ ll carefully package and ship your certified diamond once you give us the go-ahead.
Frequently Asked Questions
Have questions? We’re here to help
Why are some custom-cut diamonds more expensive?
remove
add
Several factors can raise the cost:
· Unusual elongated ratios
· D or E color
· VVS clarity
· Custom pavilion or crown angles
Note: #1 and #4 often require large rough stones and result in higher loss during cutting. #2 and #3 typically require reworking pre-certified stones, which increases the cost significantly.
Am I able to see a 3D model before making payment?
remove
add
Unfortunately, we cannot provide a 3D model preview, either before or after payment. Each rough stone is unique, and our pre-inspection tools only offer preliminary clarity and weight estimates. Much of the preparatory work—such as stone selection and feasibility evaluation—can only begin after an order is confirmed.
What if I want changes after the cutting process starts?
remove
add
Because of the extensive prep and planning involved, we do not recommend making changes once cutting has started.
