Tourmalines make very popular jewelry stones and come in an amazing range of colors, including multi-color zones. Tourmaline is the modern October birthstone, and pink in particular is a very popular color.\n\nMost colors are fairly common, but pure blue, red, orange, yellow, and purple stones are rare. Such stones usually command higher prices. Color-change tourmalines are also exceptionally rare. Neon-blue paraíba tourmalines, raspberry-red rubellites, and emerald-green chrome tourmalines are especially prized\n\nTourmaline crystals are often cracked and flawed, which puts a premium on clean gemstones, especially those over 10 carats in weight. Generally, the only acceptable types of inclusions in cut tourmalines are the tubes that, when densely packed, produce a cat’s eye effect in cabochons. The “eye” in a cat’s eye tourmaline can be very strong, especially when set against a richly colored gem.\n\nblue tourmaline\nfaceted tourmaline\nTourmaline Gemstone\nRing Stone\ncushion shape\nink blue tourmaline\ntourmaline beads\ntourmaline jewelry\ntourmaline ring\nJewelry Making\ntourmaline stone\nRing Making\nOctober Birthstone","brand":"Faran Gems","offers":[{"title":"Default Title","offer_id":56600297374001,"sku":null,"price":2800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/5516\/6513\/files\/baeed267-il_fullxfull.6655454624_54gv.jpg?v=1791040616","url":"https:\/\/farangems.com\/products\/ink-blue-tourmaline-stone-4-40-ct-faceted-cushion-gemstone","provider":"Faran Gems","version":"1.0","type":"link"}
