This is a wonderful specimen of light-yellow calcite wreathed by colorless stilbite crystals from the Beaver Valley Quarry in Shine, Washington. The scale of the photo is about 4 cm. This specimen was recovered from the upper pit and aptly demonstrates the perfection seen within premier specimens recovered from this small somewhat obscure Olympic Peninsula locality exploiting Eocene Crescent formation basalt. With work, specimens like this can still be found today!
