14mm/6mm doll eyes using kyanite in the iris. For the whites of the eyes and coating, I've used Padico's Resin Shizuku (Star Drop), Gem Drop White, and Star Drop Gloss to prevent yellowing. There may be some fine air bubbles, and the edges and backs may not be perfectly finished. Also, due to the nature of resin, it may break if strong force is applied. Natural stones may have slight color variations, inclusions, and cracks, but please understand that these are part of the charm of natural stones. Due to digital images, the colors may differ from the actual product, and considering that these are handmade items, please refrain from purchasing if you are looking for perfection.
