This stunning set includes our exclusive double-sided gem blocks, featuring pointed-back AB-coated gems that shimmer and shift with every flicker of light. Each gem radiates rainbow hues, glistening like fresh snow under twinkling fairy lights, creating an utterly enchanting play experience that feels truly next level magical. Together, these pieces create a delightful festive setup, perfect for small world play, sensory exploration, or as a beautiful keepsake display that captures the joy of play. Brilliant, prismatic windows + satisfyingly chunky beechwood = instant kid magnet.

Indoors or out, they’re an easy yes for Montessori-inspired and Reggio-style play.
