About Us

Two years after the launch of the Gemfish IF1 Flashlight, the brand continues to evolve. What began as a single, high-quality tool designed specifically for gemstone professionals has now grown into a range of products that support the wider lapidary process.

Founded by opal merchant Justin Thomas, Gemfish was born from a desire to create tools that truly serve the needs of colored gemstone cutters and traders—filling a gap left by generic lighting solutions and diamond-focused tools. With the Gemfish IF1, it proved that precision, durability, and innovation could be brought together in one tool.

Gemfish is proudly part of the Black Opal Direct family, a company dedicated to sharing Australia’s national gemstone, opal, with the world. Building on decades of experience in sourcing, cutting, and teaching opal, Black Opal Direct provides the foundation of knowledge and expertise that drives Gemfish forward.

Now, as we expand the Gemfish range, our mission remains the same: to create professional-grade equipment that enhances clarity, accuracy, and confidence for gemstone professionals worldwide. Proudly based in Australia, Gemfish is building on its foundation to deliver tools that will continue to shape the future of lapidary work for years to come.
