All of our colored stones are responsibly and ethically sourced, with practices in place that consistently exceed industry regulations. Our diligence and attention to detail in every component of exchange along the supply line assures that we can be proud of the gemstones we provide to our wholesalers, jewelers, and designers.

Rockstoc specializes in rare Burmese spinel, unheated rubies, and sapphires, but we carry colored stones from all over the globe. Regardless of origin, our gemstones are hand-selected and ethically sourced by us to meet our quality standards.

Whenever possible, we buy directly from local miners and the communities in which they live to minimize the number of middle-men in the supply chain. By doing so, we both recognize the pivotal role of these key players and help to ensure that our investment helps to provide training and employment opportunities for the next generation.


Our owner and founder, Yvonne Jiew, has worked in the colored stone industry since 2004, selling fine gems ethically sourced from mines around the world. For almost two decades, Yvonne has put in the hard work to build a brand that gives back.

At its core, Rockstoc is built on the desire to support small businesses here and abroad through fair and transparent, authentic dealings.
