Dave Englund > Close-up of the Brazilian. Again, a quartz and pyrite filled cavity, accented by some beautiful yellow and red banding.

Dave Englund > 1.5oz Lake Superior Agate; 4.2cm x 3cm x 2.7cm.

Al natural ("water polished," by virture of having spent hundreds of years in a creek bed with water running over it's surface).

Dave Englund > 2.5oz Lake Superior Agate; 5cm x 4cm x 3cm.

Another water polished agate. Note the yellow regions in the lower-left. These are likely regions with higher iron content.

$Dave Englund > 2oz Lake Superior Agate; 5.2cm x 3.4cm x2.5cm. A fine little water polished agate with multiple fractures.$

$Dave Englund > Lake Superior Agate. Note the crystal impression (lower left). Again, what appear to be fractures running up the face and branching out at the top are simply edges of reflections. Someone did an outstanding job of polishing this rock - the face and banding are remarkably smooth and clear.$

$Dave Englund > 3oz. 4.5cm x 4.5cm x 2.7cm. This fine Lake Superior Agate was purchased at a rock shop in Beaver Bay, Minnesota. Note the very defined crystal impression lower-left of center. To date I have identified only two small fractures on this rock. One is on the lower-left in this shot, running up to the large crystal impression. The other is on the back bottom edge of the rock. What appear to be fractures running up the face in this shot, and branching out at the top, are only edges of reflections. This is a remarkably un-fractured rock for it's size, and it is a jewel in it's own right.$
