King's Manassa Turquoise

Manassa, Colorado

One of our home mines. Earthy green-to-teal stone with warm landscape matrix.

Where it comes from

King's Manassa turquoise comes from the Manassa mining district in Conejos County, southern Colorado. The deposit sits in the foothills of the San Juan Mountains and has been mined for turquoise since prehistoric times. The Ancestral Puebloans worked the area centuries before European contact, and commercial mining picked up in the late 1800s under the King family, which is where the modern name comes from.

It's one of only a handful of historic Colorado turquoise sources still producing usable stone. Production is small, the rough is hand-selected, and there's no industrial-scale operation feeding the market. That keeps the supply tight and the material honest.

What it looks like

King's Manassa turquoise leans green more often than it leans blue. The classic color is a warm, slightly yellow-green to deep teal, often with a brown or golden host-rock matrix that wraps around the stone in irregular patterns. Some pieces show clear blue zones, and the best material can rival any Nevada green for color depth.

The matrix is what really sets it apart. Manassa tends to come out of the rock with rich, earthy iron and sandstone inclusions that look more like landscape than veining. Each cab reads almost like a tiny topographical map.

What makes it special

The green-to-teal color story is genuinely distinctive in a market dominated by blue-leaning American turquoise. Pair that with the warm landscape matrix and you get a stone that feels different in the hand and on the body. It connects to a different palette and a different geography than most of what's on the market.

And because production is small and hand-worked, no two pieces of Manassa look alike. Even within a single batch of rough, the patterns vary widely. That makes every piece a one-of-one in a meaningful sense.

How to identify it

Look for the green-to-teal body color paired with warm brown or rust matrix. The matrix often forms larger blocky shapes rather than tight spiderweb, and the host rock frequently shows through the polish. The hardness is moderate. Manassa is generally cut from natural rough that takes a good polish without stabilization in the higher-grade pieces.

If a stone is labeled "Manassa" but shows the bright sky-blue and tight black matrix typical of Kingman or Sleeping Beauty, that's a tell. True Manassa rarely looks like that.

King's Manassa in our collection

This is hometown turquoise for us. Greg has been working Manassa rough for years, and we set it because we know the material from the inside out. It pairs especially well with sterling and with rougher silversmithing styles, and it shows beautifully against tan, rust, and forest-green palettes.
