Introducing our UNAI Ring our latest setting, designed to highlight the quiet strength of an exceptional stone. At its center a 2.11 carat natural Old Mine diamond with a rare champagne hue, mounted in warm 18k yellow gold. Set in a compass-style four-prong, the stone’s softly geometric cut and antique charm reflect the rich history of old mine diamonds. A refined, minimal setting lets the diamond speak for itself — a truly uncommon beauty, both in color and character.
Being a one-of-a-kind piece, this ring is sold as is. Please contact us at hello@mati-jewelry.com for custom requests or size inquiries.
