This watermelon tourmaline necklace is a dainty, pretty style. In this simple design, a genuine tourmaline gemstone in a lovely shade of pink is centered on fine, rose gold-filled chain. This off-round stone measures about 8mm and contains shades of both pink and green. Small rose quartz stones connect the lobster clasp. This necklace is about 16" (40.6cm) in length, so it is a little longer than the usual choker length. If necessary, I would be happy to adjust the length for you. Your jewellery will be packaged in a small gift box. Gift wrapping is available upon request. What is Gold-Filled? Gold-filled is an economical alternative to solid gold. By law, it has 1/20th by weight layer of 14 karat gold permanently bonded over a core of base metal. It is tarnish-resistant, safe for sensitive skin and unlike gold plate, it will not wear off. It is a great way to enjoy affordable gold jewellery.
