Every Diamond Has Its Own Identity.
Highline uses lab-grown diamonds selected to our D–F color and VS+ clarity standards. Individually certified diamonds of 1.00ct and above are accompanied by an IGI grading report and laser inscription. Smaller pavé and accent diamonds are quality-matched but are not individually certified unless expressly stated.
