The world's largest supplier of oolitic aragonite. A pure, renewable calcium carbonate, harvested from the shallow waters of the Bahamas.
01 · Origin
Aragonite Source is run 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 chosen two ways: they test uniform, and they renew.
The job is to deliver on time, always to specification. We have never had a rejected load, and we have never failed to meet customer demand.
Where the Atlantic meets the Gulf Stream, on shallow banks, aragonite forms.
From the archive · 1971
The sugar-white sand that has lured tourists to Bahamian beaches for years is about to become one of the islands' most important mineral resources.
02 · The Mineral
Limestone takes millennia to form, and varies wildly inside a single deposit. Aragonite is forming right now, while you read this. What is aragonite
Bahamian oolites are a very pure calcium carbonate. Ovular grains, built from needle-like crystals that clump together as they precipitate to the ocean floor. Same chemistry, load after load.
Limestone is finite. Aragonite forms continuously, and in great numbers, where Atlantic waters converge with the Gulf Stream. A mineral resource that renews itself.
Phytoplankton pull carbon out of the atmosphere. It binds with calcium in seawater and settles to the ocean floor as aragonite. Harvesting shallow water can even increase the rate at which it forms.
