What to Look for When Shopping for Lab-Grown Diamond Necklaces
Quality
When shopping for a lab-grown diamond necklace, quality and certification of said quality is key. “Good quality lab-grown diamonds look exactly the same as natural diamonds,” explains Yuvi Alpert, Founder of Noémie. Quality will determine how much a diamond sparkles and you, of course, want that dazzling shimmer effect.
Certification
With quality in mind, Alpert says it is “vital” that lab-grown jewelry comes with a [diamond] certification card such as a IGI or GIA certificate “to know precisely the quality and type of diamond.”
