About the stone

What is Orthoclase?

Orthoclase is a potassium feldspar and a main part of granite. It sets the value 6 on the Mohs hardness scale.

It is common in India's granites and pegmatites; clear yellow orthoclase from Madagascar is cut as a gem.

Care & cleaning

Clean with lukewarm water, a drop of mild soap and a soft brush, then dry with a soft cloth. Store apart from softer stones to avoid scratches.
