How your purchase supports the supply chain.
Every purchase you make with Columbia Gem House supports a responsible supply chain. We work with individual miners and cutters, while offering careful consideration and respect to the cultures, communities, and environments in which our gems are produced. These are some of the key guiding principles in how our gems are brought to market. To learn more about our process, visit our Fair Trade Gems® Principles & Protocols page.
