This is a solid new one—23 x 16 mm Royston turquoise cabochon from the mining district, with that classic matrix swirl of sky blue, green, and brown tones. Set in sterling silver with a beaded bezel for detail and a split flat shank that keeps it comfortable and strong. Signed LAS inside. Size 10, good weight, sits confident on the finger. Simple, honest, and made to wear. If you're looking for Royston that feels personal and has a maker’s mark, this one's ready.
