Slyv Ztnix

Master the ancient craft of gem cutting in Slyv Ztnix — a precision simulation that puts real lapidary science at your fingertips. Select rough material from humble quartz to flawless diamond, choose a cut design, and grind every facet to the exact angle that unlocks a stone's full brilliance and fire. Every facet you place is scored against its target angle. A degree too shallow and the pavilion becomes a window, leaking light instead of reflecting it. Dial in the geometry and watch your brilliance score climb from an F-grade quartz to a near-perfect A-grade diamond blazing with dispersion fire. Twelve gemstones — from amethyst and tourmaline to sapphire, ruby, and zircon — each modeled with authentic refractive indices, dispersion values, and crystal habits. Progress through eight Master Cut challenges that push your precision to the limit. First Light eases you in with quartz and a round brilliant. Master's Diamond demands half-a-degree accuracy across all 57 facets of the hardest stone in the case. Earn up to three stars per challenge and unlock rarer rough as your skill grows. Whether you are a curious beginner or a hobbyist lapidary sharpening your mental geometry, Slyv Ztnix rewards patience, precision, and an eye for light.
