Oysto Teratta

Calcium Carbonate powder derived from Oysto Teratta species is considered the best quality. These species are highly fibrous in nature. The powder derived from Oysto Teratta has a flaky texture, apart from calcium, it also contains magnesium of about 1.5%. These shells are very fragile and clean. The availability of these shells is limited, however, we have contracted a number of excavation teams all around the globe to get us the best quality & un-interrupted supplies throughout the year.


This is another specie of oyster shell calcium that is available in abundance. The assay as CaCO3 is less as compared to Oysto Teratta, however, this is a cheaper substitute to Oysto Teratta.
