1x Howlite Turquoise Heart Pendant with SIde Hole 30mm x 25mm. Lovely and tactile, these blue green hearts have an off-centre hole. Howlite is naturally a white colour gemstone with veining, but it is often dyed to resemble other stones. This gives you a natural material with stunning colour, but at a fraction of the price of the 'genuine' article. Perfect for Valentines.
