Crystallo Rare is NSI Stone of the Year

OBERLIN, Ohio – Crystallo Rare from RSG Stones is the 2025 Natural Stone Institute (NSI) Stone of the Year.

Crystallo Rare, a quartzite sourced from a small, exclusive reserve in Rajasthan, India, offers a delicate interplay of deep grey veins scattered across a pure white background. The veins, which range from sparse to concentrated, create a sophisticated contrast.

The name “Rare” is a fitting tribute to the stone’s exceptional nature, as this specific form of Crystallo is quarried in only one small location worldwide, with a very small production of around 5000 ft²  in 3 cm.

Crystallo Rare is a sought-after choice for luxury designers and architects aiming to create timeless, sophisticated spaces.
