An 18ct yellow gold framed Millefiori glass pendant. 
"The symbol at the centre of this Murano glass medallion is a Catholic "peace cross" with a chi rho (ΧΡ, representing the first letters of Χριστός, Christ) with an alpha and omega (Α Ω) on either side which represent the beginning and the end."
Millefiori translates to a thousand flowers, which is evident in the many glass shards and powder used to create the floral effect shown in this item. 
A beautiful piece which is a gorgeous way to add a rich, pop of colour to your daily wear.
