Formed by the ocean. Renewed every day.

We're the world's largest supplier of oolitic aragonite — an exceptionally pure, renewable calcium carbonate, harvested from the shallow waters of the Bahamas.

01 — Origin

Five decades on the water, one uncompromising standard.

Aragonite Source is operated by the former principals of Marcona, who harvested aragonite at Ocean Cay from the 1970s into the early 2000s. Today, in close conjunction with the Bahamian government, we dig at sites selected for remarkably uniform product testing and robust environmental renewability.

Our mission is simple: deliver on time, always to specification. We have never had a rejected load, and we have never failed to meet customer demand.

02 — The Mineral

Why aragonite beats limestone

Limestone takes millennia to form and varies wildly within a single deposit. Aragonite is forming right now — as you read this.

01
Composition

Exceptionally pure

Bahamian oolites are a very pure form of calcium carbonate — ovular grains built from needle-like crystals that clump together as they precipitate to the ocean floor. Uniform chemistry, load after load.

02
Renewability

Constantly forming

Limestone is finite. Aragonite forms continuously and in great numbers where Atlantic waters converge with the Gulf Stream — a genuinely renewable mineral resource.

03
Carbon

Born of carbon capture

Phytoplankton pull carbon from the atmosphere; it binds with calcium in seawater and settles to the ocean floor as aragonite. Harvesting shallow waters can even enhance the rate of formation.

05 — The Journey

One supply chain, harvest to delivery.

Harvest

Sites in the Bahamas chosen with the Bahamian government for uniform testing and renewability.

Ship

Controlled shipping into the U.S. — product integrity from the water to our facility.

Process

Sized to the correct gradation at our facility — chemistry and composition matched to each industry.

Deliver

Our own dedicated truck fleet plus rail from our own yard — consistent and on time.
