2 options if either all rainbow moonstone or a mixture of moonstone/labradorite/kyanite.
length of "drop" is @2in. Chain length is adjustable from 16-18inches with lobster clasp.
Shapes and sizes of the stones will vary from piece to piece. As with all natural gemstones, natural variations occur. If you are concerned about how this will work out, feel free to contact me and I will try to give you stone options.
