This is a 20mm heart in our Marmo line of Murano glass beads with swirls of red mixed with aventurina and 24kt gold foil to create a marble-like effect. This heart is approximately 20mm top to bottom and across and approximately 14mm thick. The hole runs vertically through the bead top to bottom and is approximately 1mm in diameter. They are handmade and the exact location of the colors, gold foil and aventurine vary.
