Sardonyx is without doubt my favourite type of agate. The pale powdery lilac sat on top of deep orange catches my eye every single time. When its set into 18ct gold like this handsome chap is, it's the perfect combo.
 
Every collection should include a signet ring. This will be one of your most hard working items.
