Blue/black Agate Signet Ring, Sterling Silver

$350.00

A bold signet style ring featuring a striking blue-black agate cabochon gemstone set in sterling silver. The deep, inky tones of the agate reveal subtle variations and natural patterning, creating a stone that feels both dramatic and timeless.

Tania is well known for her love of semi-precious stones and gems, with many of her favourite personal pieces celebrating these endlessly varied natural treasures. Each gemstone is carefully selected with a discerning eye and finished beautifully, then professionally set to bring out the very best character of the stone.

This cabochon style stone has been shaped and polished rather than faceted. Its smooth domed surface enhances the agate’s depth of colour and gives the ring a soft, tactile feel.

This piece is created to provide both comfort and quality. Tania's rings are more substantial than many handmade comparisons, and each band interior is carefully shaped with a gentle curve and softened edges for maximum comfort on the finger.

Rings often signify love, commitment, and creativity, making them a meaningful gift for someone special — or a beautiful treat for yourself.

Sterling silver is an alloy containing 92.5% pure silver, resulting in a metal that is durable, long-lasting, and easy to maintain. It can be easily polished using a polishing cloth. All Tania Mallow jewellery is certified sterling silver.
