Three gemstone rings in one pack, about 25% off the single prices ($93 if bought separately):

• Ruby and Diamond Bypass: 6 x 4 mm pear ruby in a bezel and a 4.5 mm round diamond in a four-prong basket, 3.52 g sterling
• Peridot Branch: textured twig shank, two 5 x 2.5 mm marquise peridot leaves and a 1.8 mm diamond dewdrop, 3.54 g sterling (fine twig detail is under 0.8 mm in places)
• Cathedral Solitaire: six-prong cathedral setting for a 6.5 mm (about 1 ct) round brilliant diamond, double gallery, 3.13 g sterling

Ring size: US 7.5 / EU 56 (inner diameter 17.83 mm, ISO 8653). Modelled in real-world millimetres.

Included per ring (one zip each)

• Blender (.blend): Cycles studio scene with cameras and a 180-frame turntable, all textures packed
• FBX and OBJ + MTL: ring and stones, mm units
• STL: metal only, casting-ready (watertight single shell, 0 n-gons)

Weights are for the raw casting in sterling silver 925; expect roughly 5-10% loss in cleanup. Stones are not part of the STL; order them to the listed mm sizes.
