A lab-grown diamond is chemically, physically and optically identical to a mined one — same fire, same hardness, same certified grading — grown rather than dug. This is everything in the collection set with them: solitaire and three-stone engagement rings, pavé charms, diamond studs and hoops, all in solid recycled gold.

For the woman who wants the big-diamond look with values attached, styled for everyday wear rather than locked away. The glow, not the flash.

Are lab-grown diamonds real diamonds?

Center stones at 1 carat and above are IGI certified.

Are they certified?

Center stones at 1 carat and above are IGI certified.

Why choose lab-grown?

Same brilliance and durability as mined, with a traceable origin and more carat for your spend.

What metal are they set in?

Solid recycled gold, never plated — so it holds its colour, won't tarnish, and can be worn every day, shower and sleep included.
