Hundreds of certified semi-precious stones — Iolite, Opal, Onyx, Agate, Peridot, Amethyst, Moonstone, Turquoise and more. Many are worn as upratna — substitute stones for the Navratna — with Iolite and Jamunia standing in for Neelam, and Sunela for Pukhraj. Others are bought simply for their colour. Every stone comes with a lab report from an independent gem testing laboratory and the same Authenticity Guarantee as our precious range. Browse by stone below, or filter by price and carat weight.
