When Bill Kasso starts cutting his rough boulder opal, koroit opal, yowah opal, etc... it is a very exciting time for him and of course for me. When I saw these leaf shape boulder opals that he cut for me I flipped. These are going to be big earrings; not for the faint of heart, or worried about when one is going to wear them... you just do, much like the Nike sentiment... Iv'e accented them with 6mm blue zircons (that are luscious), and tsavorite garnets to pull out the famous blue/green tones that are cradled in the iron stone matrix.
