7+ Pound Banded Blue Agate with Geological Oddity Found Inside

7+ Pound Banded Blue Agate with Geological Oddity Found Inside

The ‘deep pit’ on The Carver agate field ‘popped’ a 7+ pound,  6 1/2″ x  3 3/4″ banded blue agate beauty! While the ‘deep pit’ photo gallery on this website has lots of photos of ‘deep pit’ beauties, this specimen contains a large yellow inclusion (on the left side of the photo below) which has a blackish dendritic agate formation in and on its surface. A dendritic agate is a tree-like or fern-like image.  The word dendrite is Greek for “tree-like.”  Normally, these dendritic formations from The Carver have formed on the outside surfaces of a geode or nodule, as shown below in photo 2849.  What is geologically odd is that this dendrite formed on the yellow material which broke off and fell into the gas bubble pocket, which was then encased inside the larger blue agate when it later formed. I believe this was likely an 8-step geological process, […]

Metallic Mystery Agate

Metallic Mystery Agate

This agate formed in association with a yellow jasper (which is predominantly comprised of silica). Before I cut this Carver find, it displayed a curious metallic sheen which was in fact what initially drew my attention to it.  The sheen was very different from the sheen observed from other quartz and jasper materials.  This metallic sheen appears quite clearly on the bottom of the pictured cabochon. The rounded surface of the cabochon shows agatization and two visible “vugs.”  The stone from which this cab was cut also had a curious and unexpected heft (weight) that, combined with the metallic sheen, suggested a metallic component had mixed with jasper and formed  a metallic mystery agate that had not been previously observed on The Carver agate field. If I can find out what metal is involved I will update you.
