This is the solid 9ct gold version of the pendant.  I am married to a lovely Irish man, and one of my favourite Irish phrases is 'Cuisle Mo Chroi', a term of endearment meaning 'beat of my heart'.  The Cuisle (pronounced 'Kooshla') pendants are cast from an original silver form I made and come supplied on an 18" 1.7mm wide 9ct gold trace chain.
Super comfy, light to wear and it goes with everything!
Silver and gold vermeil heart option also available.
