Weighted Acrylic Pool Gems & Treasure Box

A complete aquatic play set comprising 10 large, vividly pigmented acrylic gems (~3 cm / 1.18 inches diameter) and a themed pirate treasure chest — both crafted from solid, non-toxic acrylic. Each gem is calibrated by mass to sink predictably and gently in standard pool depths (1–1.5 m), supporting safe, repeatable underwater interaction. Colour is embedded uniformly within the acrylic — no surface dyes or coatings — eliminating fading, chipping, or chemical leaching over time. The treasure chest includes precision-engraved nautical motifs and a secure hinged lid, sized to store all 10 gems neatly. Developed for children aged 3–8 to nurture visual tracking, breath regulation, hand-eye coordination, and comfort in water through joyful, repetitive discovery.
