Is aragonite in the Bahamas?
Aragonite or Ooid sand is one of two types of sand found in The Bahamas. Regular sand or biogenic sand is formed from skeletal debris of animals and plants. “It is estimated that 12,266 – 23,354 million metric tons of aragonite exist in The Bahamas.
Where does aragonite sand come from?
Massive deposits of oolitic aragonite sand are found on the seabed in the Bahamas. Aragonite is the high pressure polymorph of calcium carbonate.
How much money is aragonite worth?

What Bahamian island has rich deposits of aragonite?
NASSAU, BAHAMAS — Andros cannot be developed “at the risk of sustainability” according to Environment and Housing Minister Romauld Ferreira. Ferreira was speaking at the eighth annual Andros Business Outlook. He noted that the island has the largest deposits of aragonite in the country.
Why does aragonite dissolve?
Unprotected shells and skeletons dissolve when carbonate ions in water are scarce – it is undersaturated or corrosive. The saturation state Omega (Ω) describes the level of calcium carbonate saturation in seawater.
How do you know if aragonite is real?
The best way to know if an Aragonite is real is to be familiar with its physical properties. Aragonite appears as a white or colorless or white mineral that can sometimes show shades of light yellow, violet, and blue. It also exhibits distinct cleavages on particular axes. It’s naturally very brittle, too.
Why is aragonite rarely used in jewelry?
Aragonite’s hardness is too low for this stone to be worn safely in jewelry. Avoid mechanical cleaning such as steam or ultrasonic processes.
What is aragonite sand used for?
Scientists use oolitic aragonite sand to reconstruct the route and speed of past currents and ocean circulation patterns. The grain size and sand body size indicate the strength of the current that formed the oolitic sand.

Where does the oolitic aragonite in the Bahamas come from?
Oolitic aragonite is a renewable and sustainably sourced resource. It naturally forms on the banks of The Bahamas during natural precipitation events called ‘whitings.’ During these events, blooms of cyanobacteria sequester carbon from the atmosphere and a mineralization process occurs, forming oolitic aragonite.
What kind of sand is in the Bahamas?
Most of the topography of the Bahama Banks is composed of calcium carbonate oolitic aragonite sand material. The natural formation through precipitation, sedimentation and possibly microbial activity of aragonite sand in the Bahamas surpasses anyplace else in the world.
How does oolitic aragonite sand form in water?
Oolitic aragonite sand forms in high-salinity waters that are turbulent, shallow, and warm. The sand starts to form around a nucleus of calcium carbonate, such as a peloid, shell fragment, or foraminifer. The nucleus is coated with a thin layer of crystalline carbonate to form the cortex of the ooid.
