This collection contains rings of all US sizes from 2 to 14.5 in increments of 0.5
Thickness: Single (One line of diamonds) : 2 mm,
Profile height: 1.46 mm
Diameter: Size chart is in pictures = from 13.2mm (US2) to 23.5mm (US14.5)
All rings are in formats – 3DM (Rhinoceros), STL (Stereolithiography), 3DS, FBX, OBJ, STP
Mass: Single(US2): 0.125 sm3 = 2.41g (Gold) + 24 Diamonds 2mm (0.03Ct)
Mass: Single(US14.5): 0.212 sm3 = 4.09g (Gold) + 40 Diamonds 2mm (0.03Ct)
