WIO Nano Boulder - Emerald/Jade

WIO Jade Boulder Nano Stone brings rare natural beauty, distinctive green character, and a captivating play of color to your scape — metamorphic boulders in rich green shades with rounded forms and green strata, perfectly scaled for nano compositions that evoke oriental Asian riverbeds and tranquil mountain streams.

Jade Boulder Nano Stone carries the same rare metamorphic character as the full-size Jade Boulder — formed over millennia within Earth's tectonic boundaries, with a distinctive green hue created by the presence of iron, magnesium, and other metallic elements. Each rounded piece has smooth, strata-layered surfaces that become even more captivating when submerged, producing a calming and mesmerizing visual effect. As an inert stone, Jade does not affect water hardness — making it safe for all sensitive aquatic life.

Sized between 3 and 10 cm, ideal for nano tanks under 40L. Due to limited supply and high demand, availability may be limited. Pre-washed and ready to use.
