Our Lapis is 7-8mm in diameter. Lapis is a semi-precious stone and one of the most sought after throughout history. It is highly regarded for its beautiful blue color flecked with gold inclusions of pyrite, and was prized in ancient times for the ultramarine dye derived from it. This dye was said to create Michelangelo’s favorite shade of blue. It is one of the world’s oldest known stones, mined since 4000 BCE, originally from the Lapis-Lazuli mine in Afghanistan. This Lapis has been treated to enhance the blue color.
