These spheres are very tiny 1.5mm in size and are sold individually (not a vial full or with a vial). Like all of our white opals, they have an opaque white base with brilliant flashes of green and blue fire.
The base color of white opals can vary from fairly opaque to solid white. If you prefer a semi-transparent or a more opaque base, please let us know in the customer comments during the checkout process and we will do our best to fill your request.
Did you know our Gilson Created Opal does not decompose, off gas or release any substances when heated to very high temperatures? Read more about our testing
