There are four fluorite cabochons available, size is width X length and are an approximate measurement. This item is great for fellow jewelers of any kind or stone collectors alike. I have been in the business for 10 year and over that time I have acquired more stones and jewels that just have not spoken to me but how selfish of me to keep them from who they were truly intended for! This item is not intended to be purchased for the purpose of a custom order through BellaLili. There are no returns or exchanges for supplies.
