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 18-20" 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.
