Tommy this needs it's own section. Hi Dave, faceting is a very specific niche topic and it did have it's own section here for a very long time and was not creating much activity. The most recent post in the category was a year old which is not good because inactivity breeds inactivity and is a negative for any forum. With faceting being a specialized form of flat lapping I decided to consolidate it into the flat lapping category and changed the title to include all - displays, faceting, cabochons. OK, I just had a hard time finding it.

An amazing fact about sand, it is mostly quartz crystals which are ElectretsWhen compressed they generate electricity, which makes a magnetic field and all kinds of strange things occur! Early explorers thought they were hearing spirits of the dead!

My plane stopped in Panama in the middle of the night when i flew back from Uruguay in 1960. i started getting off the plane to look around, but it was still so hot I got right back to the plane!

Trancas are thundereggs from Mexico. as they formed in calcite magma, unlike other t-eggs they opened at the very center, so don't have the middle ball core as normal.
