Sinkable Acrylic Pool Gems Treasure Set

Includes 10 large acrylic diving gems (~3 cm / 1.18 inches diameter) and 1 themed pirate treasure chest — all made from solid, non-toxic acrylic. Gems are weight-calibrated to sink naturally and controllably in standard pool depths (1–1.5 m). Pigments are fully integrated into the acrylic material — no surface coatings or dyes — ensuring long-lasting colour without fading or leaching. The treasure chest features engraved decorative detailing and a functional hinged lid, sized to hold all 10 gems comfortably. Designed specifically for children aged 3–8 to support visual tracking, breath control, hand-eye coordination, and gradual water familiarity through repeated, playful underwater retrieval.
