A set of 21 smooth magic crystals/stones (1500 x 2500px 350dpi) in different colours for jewellery and decoration.
The crystals are partly transparent and most of them look better on darker backgrounds but adding a layer of darker colour of your liking beneath only the crystals can make them stand out more if needed.
Example of use:
I recommend adding glow and/or sparkles if you want to make them look even more magical.
