Black Agate Square Natural Stone Coasters – Set of 4

Make a sophisticated statement with these Black Agate Square Coasters, handcrafted from natural agate and finished with a beautifully substantial electro-formed metallic edge. Their deep, dramatic stone tones create an elegant contrast with the luminous metal, making them as decorative as they are practical.

Sold as a set of four, each coaster brings the natural character of genuine stone to your table while adding a refined artisan touch to everyday entertaining.

The Beauty of Natural Black Agate

Black agate is prized for its rich, mysterious appearance and natural mineral character. Each stone has its own subtle variations in color, pattern, texture, and translucency, creating a naturally individual look.

Because these coasters are made from genuine natural stone, no two pieces are exactly alike. The variations are part of their authentic beauty.

Real Metal, Permanently Bonded

The edges are finished using an electro-forming process, where real metal is grown directly onto the stone and permanently bonded to its surface.

Unlike a simple metallic leaf or coating that can rub away, the electro-formed edging becomes an integral part of the piece, creating a distinctive frame around the natural agate.

Choose from:

Gold — warm, luminous, and luxurious

Silver — sleek and sophisticated

Rose Gold — soft, elegant, and contemporary
