Why We Love It

This stunning marquise gives off the most beautiful and unique subtle pink hue. Brown diamonds and pink diamonds are very closely related so their hues can be similar and we definitely see more pink/peach leaning hues in this remarkable stone. Set with vibrant white side stones to highlight the center stone, this Marielle offers full finger coverage with plenty of hefty diamonds. Each of these diamonds has a beautiful, true antique make. 

The dimensions of the center stone are 15.23 x 8.19 x 4.43 mm.
