Purple PyropesDoing a bit of research on the significance of Purple Pyropes, I found the below.
Question. The discovery of what semi-precious stone often indicates that diamonds are nearby?
Friar Tuck says:

ALAN ALDA (NARRATION) 'So finding diamonds means that you must first locate kimberlite pipes'
CHUCK FIPKE 'These are diamond indicator minerals, some of which actually grow with diamonds. These purple pyropes, here, they actually grow with diamonds.'
ALAN ALDA (NARRATION) 'Finding these minerals would mean diamonds must almost certainly be nearby.
