Description:
Yellow meliphanite on a feldspar matrix with a few tiny zircons. The meliphanite fluoresces an interesting pink/violet fluorescence under midwave UV light, shifting to a deep violet under longwave UV light. The fluorescence is not the strongest, but very unusual colors. A section just next to the meliphanite seems to fluoresce much stronger and more pinkish, with orange afterglow; not sure what that is. Under shortwave UV light, the feldspar fluoresces deep, weak red, while the zircon are bright yellow.
