Greetings, all,
 
 
In the experience of the chondrite-cutters, how common are you finding ringwoodite in shock melt veins?
 
Personally, I've only seen (what I believe to be) ringwoodite in two stones out of the dozens I've cut.
 
How about size? In mine, the largest area is ~ .5 mm.
 
For such an outstanding indigo blue colour in a generally brown matrix, I'm surprised there isn't that much information about the mineral in meteorites on the internet or my books.
 
Cheers,
Pete
