Here we have a beautiful specimen of chromium-bearing Diopside from Outokumpu in Finland, definitely way better in person due to the circumstance, that the pictures cannot convey the good aesthetics and cyrstallisation of the piece. Definitely a classic, old-time specimen of lustrous, emerald-green Chrome-Diopside crystals on Quartz matrix from the well-known Outokumpu area of Finland. Highly representative for the species and location. Rare too - this is old stuff. Ex Robert Jakob collection.
