3.45 ct Platinum Old Mine Coursiere

$ 85,050.00
Size

When we set eyes on this extremely rare antique diamond, we knew it needed to be seen to be believed. The subtle architecture of this solitaire setting lets the fantastic faceting of this 3.45ct larger-than-life old mine cut diamond shine its brightest. Stacked deep or worn alone, this solitaire is for the dreamers—come try it on in person and see what made us fall head over heels. Made in San Francisco.

Platinum set with a GIA Certified 3.45 carat Old Mine Diamond (E SI2 Clarity).
