Description

The quartz crystals are not just milky, they more remind to porcelain, they are highly lustrous and show sharp termination and developed a radial assemble. Along their edges they are framed with tiny, psrakling calcite crystals. It is - unforutunately more or less impossible to show luster on a white mineral and I only can assure you that this piece shows superb quality. Developed ass floater and great in each angle. No significant damages to report.
