Practical calculators for jewelry design, gemstone geometry, precious-metal measurements, material evaluation, and jewelry production.

This collection brings together tools that support accurate calculations and informed decisions throughout the jewelry-making process, from working with raw materials to evaluating finished pieces.

Each calculator is designed to address a specific task, with clear inputs, transparent methods, and results that support practical work.

Jewelry Calculators — diamonds, gemstones, precious-metal ingots, a digital scale, a gold ring, and a precision caliper arranged with technical drawings and mathematical formulas on an ivory background.

Precious Metal Mass Calculator: \(m = ρV\)
Precious Metal Weight & Force Calculator: \(F = m × g\)
Precious Metal Price Calculator: \(m_fine = m × (f / 1000); P_{\mathrm{item}} = (m_fine / 31.1034768) × P\)
Precious Metal Reference Value Calculator: \(m_f = m_g × F / 1000; P_g = P_u / B_u; V_r = m_f × P_g; V_a = V_r ± A; V_c = V_r + Σ(s_i × C_i)\)
Diamond Carat Mass Estimator: shape-specific empirical dimensional estimates; see each model
Gemstone Dimensions & Geometry: \(R = L / W; V_box = L × W × D\)
