Your Complete Guide to Blue Sapphires + Blue Sapphire Engagement Rings
Australia
The look: Moody, inky blues with depth and drama — plus some of the most striking parti sapphires on the planet. Here you’ll find intense color zoning, graphic splits, and stones that’ll induce a gasp or two.
How we source: Australia is home to highly regulated, environmentally conscious mining operations. We partner with suppliers with full traceability and mines who follow strict land-restoration, environmental guidelines, and labor standards.

Tanzania
The look: Vivid, lively blues with watercolor zoning and subtle color shifting magic. Think sunlit horizon shifts — vibrant, dimensional, and full of movement.
How we source:We source Tanzanian sapphires through Moyo Gems, a women-led, community-first mining initiative supported by PACT. Miners set their own prices, earn fair wages, and work under safe, transparent conditions — plus every stone comes with full mine-to-market traceability. It’s one of the most ethically robust artisanal mining models in the world, which is why we love working with them.
