I decided to give myself a challenge and produce long stone beads this year. I have gone back to batch production which entails making a few hundred bead preforms then pausing to drill them all and when that is completed the finishing begins. I cheat and drill and finish a few that I find interesting. Here are three.

Yellow jacket jasper bead, Washington. 62 mm long, 2.5 mm hole

Long bead of a mix of grossular garnet, diopside, and idocrase. 56 mm long (2.5 inches), 2.5 mm hole

These two are rough from local to me stones.

This silicated volcanic ash bead is about 60 mm long also. The rough is from Chile.

Chilean volcanic tuff on jade. The original tuff was green and fluids have metamorphosed it adding silica, iron, and in some areas bleaching the stone to white.

For clarity I will replace the word bleaching with leeching to insure that it is understood as a natural process.

Hate to say this, but I like the matte rough a lot! :-)

The outside and cut face of a piece of grossular garnet chrome diopside rough similar to the one that the previous bead was made from.

This stone is a meta-chert, a chert which has been metamorphosed yet again. The black layers are various iron minerals and the yellow areas are a type of manganese garnet, spessartite. The garnet crystals are very small and aggregated in bunches that the geologists call garnet trains. The entire rock is over 90% silica, a hard jasper. In the field the outside of these metacherts are covered with spalling from collisions in the glacial flow and/or stream beds. This makes the rock look less saturated in color than it really is inside.

Hello Frank.

You are making great things.

You might reconsider "bleaching" in your descriptions. This has a specific meaning, and is usually inaccurate for minerals.

I suppose one could say "leeched" or "transformed."

I piggy-back on the issue that chemically-decorated agate beads are sometimes said to be "bleached." But this likewise misunderstands or miscommunicates the actual process and issue.

Good work! Jamey

Leeched is fine. The fluids essentially move ions around stealing and gifting willy nilly.
