Dendritic Opal rough round chunk (Merlinite) 1 lb. specimen

Origin: Western Australia

Characteristics: Small 1 lb rough specimen, white Quartzite and black Manganese, natural stone round nodule. A great looking specimen as is or you could cut it for some beautiful slabs or cabs. Perfect size for a small specimen cabinet.

There is confusion about what they are calling this material. Its real name is Merlinite but most call it Dendritic Opal mainly because of the opalescence (chatoyancy) in the white Quartzite, and the manganese (moss like) dendrites.

Approx size: irregular 3 " round nodule. Weight 1.1 lb.


10 mm background squares in my pictures will also help you with image sizing.

I use a full spectrum 45 w light bulb - photography photo CFL 5500K. It's a daylight balanced pure white light.
