Black Agate Flat Round Cabochons
These natural black agate flat round cabochons have a deep, rich black colour and a smooth, polished surface. The flat profile gives a sleek, low profile finish, making them especially suitable for bezel settings, ring blanks and designs where you want the stone to sit neatly against the skin or metal.
Black agate is a popular choice for its bold, sophisticated appearance and excellent versatility. It pairs beautifully with both silver and gold, and works well in both minimalist and statement pieces.
