A kilogram of stone weighs as much as a kilogram of water. A cubic meter of stone weighs about 2800 kg while a cubic meter of water weighs exactly 1000 kg.
The mass of a stone in water is the mass of the stone outside water. The mass of an object is always its mass. (This assumes we are not discussing the theory of relativity.) On Earth, or the Moon or in water or not, mass is mass. What might be relevant, however, is the weight of a stone in water compared to the weight of a stone outside the water. Weight and mass are different. If you hold a stone in water and hold the same stone in air, you can feel a difference in the force you must apply to support the stone. In water, the stone feels a buoyant force equal the the weight of the water displaced. That is Archimedes principle. There is a difference in the apparent weight of a stone in water and a stone out of water equal to the eight of the water displaced.
One stone is equal to 14 pounds.
Correct formulation: "How much does a stone weigh in salt water?"Answer: The same as it does in the air, water, anywhere.
It is more dense than water, and [presumably] it is not shaped in such a way that all of its weight can be displaced before the stone submerges.
Lead weight, a stone, the list is endless.

you subtract the weight of the water from the weight of the measuring cylinder and you get the volume of the stone
Let us say the stone is suspended in a medium by an ideal spring, which displays the "weight" of the stone in that medium. The stone reads "w" pounds in weight in air. The same stone will read less in water (w-x); the stone, being a solid, displaces an amount of water equal to the volume of the stone, and the stone will weigh less by the weight of the water (x). So in this case, the two weights have to be different, no matter how small the stone is, unless the stone has the same density as water or the stone is hollow with no crust thicknesses and a tiny hole to let water in -- all purely hypothetical.
The buoyant force is equal to the weight of the displaced water.

This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.

A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.

Sure. A small stone can have the same weight as an inflated party balloon. But the balloon has more buoyancy, so it floats on water, while the stone sinks like a stone.
The ship is hollow. The stone isn't. The air trapped inside the ship allows it to float - despite it weight.
