Tumbled Stone / Lay-on Stone – Rock Crystal (Disc Stone, Cracked)
The cracked rock crystal captivates with its fascinating play of light and its sparkling, crystal-like structure. A special process creates fine, net-like cracks inside, which refract light in all directions and make the stone glow – similar to frozen ice. Each rock crystal is a unique natural product of A-quality, carefully cut and polished to highlight its clarity and special shimmering effect.
With a size of approx. 25 × 20 mm, the cracked rock crystal disc stone fits comfortably in the hand and is ideal as a tumbled stone or lay-on stone. Its smooth, transparent surface makes it an elegant decorative piece and a popular collector's item.
