Near Brisbane, the continental shelf is littered with basalt pipes containing blue and yellow sapphires. Divers report finding stones over 100 carats in less than 40 feet of water. The visibility is moderate (15ft), but the payout can be life-changing.

Whether you retrofit your existing mask or buy a complete H2OGems system, you are purchasing more than a lens. You are purchasing the ability to finally see the ocean the way your dive light shows it to you—even when your light is turned off.

Wreck diving often involves silt, plankton, and stirred-up debris. H2OGems Scuba helps because the polarization cuts through the "marine snow" (floating particles). By reducing the backscatter glare from your dive light, the particles appear less like falling snow and more like faint dust, allowing you to see the actual wreck structure behind them.

Rivers carry rough garnets, zircons, and sapphires into the sea. Ocean currents then sort them by density. The "heavy" gems sink into troughs and crevices on the continental shelf. Unlike land panning, underwater vortexes created by waves automatically concentrate gems into "pay streaks."
