Assuming you are assessing minerals you know to be carbonates anyway, you'd obtain accurate answers only by chemical analysis.
Calcite is the most stable polymorphous form of calcium carbonate (CaCO3), a very common insoluble mineral salt. Though it contains Carbon and Oxygen it is not considered to be organic.
Carbon.
silicates
Limestone has the chemical formula CaCO3 This means it has Calcium, Carbon and Oxygen in it. The percentage of each of these elements is as follows: Ca: 40% C: 12% O: 48%
Pouring hydrochloric acid, or HCL, over a mineral will cause carbonate minerals to effervesce. This application is called the "acid test," it simply examines the mineral or rocks reaction to acid. Calcite is the most commonly found carbonate mineral and it will fizz during the acid test. Dolomite is another carbonate mineral; however, it will only fizz if it is first powdered. Experiments also show that undiluted vinegar can cause effervescing, but it produces less vivacious results. Some sedimentary rocks that fizz include chalk, coquina, oolic limestone, fossilferous limestone, and micrite. The metamorphic rock marble also fizzes.
Any mineral that contains carbonate anions. Probably the most common one is limestone.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).
Calcium carbonate. It has three mineral names, they are chalk, limestone and marble.
The most common mineral group contains silicates.
It is most often found in the carbonate mineral malachite.
Calcite is the most stable polymorphous form of calcium carbonate (CaCO3), a very common insoluble mineral salt. Though it contains Carbon and Oxygen it is not considered to be organic.
Silicates are the most common mineral group.
Limestone, made up of the mineral calcite is the most abundant carbonated rock.
Minerals with the calcium carbonate compound show effervescence. Calcite is the most common carbonate mineral.
calcite-is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCo3). diamond-is pure crystalline carbon(C).

Well as a chemist i would say it is. Most mineral samples are slightluy contamnated, whereas synthetic calcite is not.
