The Diamond Selector, manufactured by Culti of Japan, represents one of the earliest commercially successful portable diamond testers, marking a significant advancement in practical gemstone identification during the late 20th century. Designed to provide rapid, user-friendly results, this instrument operates on the principle of thermal conductivity—measuring the rate at which heat passes through a האבן to distinguish diamond from common simulants such as cubic zirconia and glass. Its introduction brought laboratory-level testing capability into retail and field environments, greatly enhancing efficiency and confidence in diamond verification.

Compact and intuitive in design, the Diamond Selector features a handheld probe and indicator system that delivers near-instant readings with minimal training required. This accessibility made it especially popular among jewelers and gem traders, contributing to its widespread adoption and establishing it as a benchmark for subsequent generations of diamond testers.

As an original model produced by Culti, this piece holds both historical and technological significance. It reflects a pivotal moment in gemology when electronic instrumentation began to transform traditional testing methods, bridging the gap between classical observation and modern analytical precision.
