Built in pure platinum and fitted with a 5x3mm oval lab grown diamond, our 1/5 carat solitaire ring favors proportion and clarity over pretense. The smooth, rounded band—2mm wide and 1.5mm thick—adds just enough substance without stealing focus from the stone. At approx. 4.57 grams, the metal weight gives it a quiet presence on the hand that speaks for itself.

About Lab-Made Diamonds

Diamonds grown in a lab follow the same rules of physics and chemistry as those formed underground. The result is a real diamond—carbon-structured, cut, and polished—without the unpredictability of traditional sourcing. These stones are made under high heat and pressure or vapor deposition, offering transparency in both quality and origin.
