About this item

These tools are compact, rugged, and field-ready, perfect for gemologists, collectors, and professionals working in labs or on-site at gem shows. Their durable construction ensures long-lasting clarity and performance, aiding rapid and accurate gemstone verification.

Designed for professionals and enthusiasts, these filters are essential for gemstone testing in India. They help identify natural vs. synthetic stones, detect dyes, and verify authenticity quickly. The set arrives factory-sealed, with all duties included, and reaches your location in 11-13 days. Whether for fieldwork or lab use, these tools support confident gemstone identification, saving time and reducing errors.
