Description :

Top Specimen — Petrified Wood (Fibrous Slab)

This long, fibrous piece is classic petrified wood. You can tell by the linear grain and the way the structure looks like frozen wood fibers turned to stone.

Plainly:

  • It’s fossilized wood where silica replaced the original organic material.

  • The texture preserves the grain of the tree.

  • Hard, dense, and usually quartz-based.


Left Specimen — Iron-Rich Mineral With Quartz Druse

This reddish-brown piece with sparkly points is an iron-rich rock coated with tiny quartz crystals.

Plainly:

  • The brown comes from iron oxides.

  • The glittery surface is quartz druse.

  • It formed when silica-rich fluids coated an iron-bearing rock.


Right Specimen — Light, Porous Sedimentary Rock

This white, chalky, porous stone is a soft sedimentary rock. It could be chalk, limestone, or a weathered tuff.

Plainly:

  • Light in weight.

  • Powdery or porous texture.

  • Formed from compacted fine sediments or volcanic ash.


Bottom Specimen — Dark Geode or Nodule Slice

This dark piece with a crystalline border is a cut nodule or geode.

Plainly:

  • The outer part is solid chalcedony or agate.

  • The inner rim shows quartz crystals.

  • It formed when minerals filled a cavity inside rock.
