Have you seen watermelon tourmaline? The unique colour combination sure makes this a juicy gem! During formation, pink and green crystals in the same stone are exposed to different minerals which cause the gem to change colour. You will often see pink in the centre, a pale zone and a green outer 'rind' just like a watermelon! #thevillagegoldsmith #watermelon #watermelontourmaline #tourmaline #gemstone #colour #pink #green #juicy #summer #summerfruit #crystals #jeweller #jewellerydesign #tvgworkshop #nzjeweller #Wellingtonjeweller #Aucklandjeweller
