Your ring, made for you in four steps
Grown in a lab, not mined.
Lab-grown and mined diamonds share the same crystal structure and essentially the same optical, physical and chemical properties. The difference is origin: one is grown in a laboratory, the other is mined from the earth.
| Lab-grown | Mined | |
|---|---|---|
| Material | Carbon, diamond crystal | Carbon, diamond crystal |
| Hardness | 10 on the Mohs scale | 10 on the Mohs scale |
| Grading | IGI or GIA report | GIA or IGI report |
| Origin | Grown in a lab (CVD or HPHT) | Mined from the earth |
| Price for the same size | Much lower | Much higher |
Proof, not promises
Every center stone comes with its IGI report
The International Gemological Institute (IGI) grades each center stone independently. The report number is laser-inscribed on the diamond, so you can match the stone to its paper.
- Carat, color, clarity and cut graded by IGI
- Report number laser-inscribed on the diamond
- Look up any report on igi.org in seconds
- Report ships with your jewelry

Questions, answered
What is a lab-grown diamond?
A lab-grown diamond is a diamond created in a laboratory instead of mined from the earth. It is made of carbon in the same crystal structure as a mined diamond and has essentially the same optical, physical and chemical properties. Every Octa Pearl center stone comes with an IGI report that identifies it as laboratory-grown.
How do I check my diamond's IGI report?
Enter the report number from your product page or certificate on igi.org. The number is also laser-inscribed on the stone.
How long does a made-to-order ring take?
12–14 business days from order to shipping, plus delivery time.
Can I return or resize my ring?
Returns are accepted within 30 days of delivery, and resizing is free.
