Questions, answered
What stones do you use?
Every center stone is a lab-grown diamond graded by IGI. The shape, carat, color and clarity are listed on each product page, and you can check the report number on igi.org.
How is a lab-grown diamond different from a mined 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. Your IGI report number is laser-inscribed on the stone, so you can check it on IGI's website.
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.
Do you offer custom or personalized jewelry?
Yes. Share your idea or a photo and we will design a lab-grown diamond piece for you, including engraving. Start your design.
Do you provide a warranty for your jewelry?
Yes. Every piece comes with a lifetime warranty covering manufacturing defects. Normal wear and tear, accidental damage and lost stones are not covered.
How long does shipping take, and do you ship internationally?
Every piece is made to order in 12–14 business days, then shipped insured. US shipping is free; international orders take 10–15 business days after dispatch. Expedited options are available at checkout.
