Description

This specimen contains in-grown crystals of red (with a hint of purple) garnet var pyrope and bright green chromian diopside. The matrix rock shows the typical yellow-orange color of altered forsterite - thus it is a peridotite. It is a rare metamorphic rock, originated under high pressure and temperature in a depth of 80-100 kms appr. 470 million years old.

This beautiful specimen has a sawn & polished face for display or positioning.
