Looks like a piece of quartz. Check the specific gravity and hardness.

Thank you so much. How can I calculate the specific gravity and hardness of quartz?
Use a sharp pointed corundum stone and try to scratch your stone and see if it scratches or not.if it scratch then its hardness is less than 9, if its not, then it could be a diamond. To do a specific gravity you need to have access to a perfect scales. Weigh your stone in air (normal weight) and then suspend the stone in the water and then check the weight.Density= mass/volume, u get the specific gravity. Quartz = 2.65 to 2.75 and diamond = 3.50 to 3.52.
Hi @Gopillm,
How to check the volume of this stone.
And I scratched the stone with a knife and it doesn't get scratches.
