Our diamonds are real diamonds with the same chemical composition and physical properties as natural diamonds, grown in a laboratory (HPHT or CVD) rather than mined. Every diamond comes with an IGI certificate that discloses its lab-grown origin.
Responsibly sourced precious metals
Our jewelry is made with responsibly sourced precious metals for modern, responsibly minded pieces.
