Hers & His
We chose to use onyx as the stone because it represents constancy, steadfastness, permanence, & courage (among many other things).
Debbie--this one is yours. It features a 25mm onyx stone set in a very feminine setting with a 18" textured chain (that matches the wire detail around the stone).
And here is Phil's. I *hope* the setting is masculine enough. This is also a 25mm stone and is on a 3mm thick natural leather cord that measures 20".
