Pink sapphire has emerged as the new October birthstone, which lends itself nicely to the modern stackable birthstone bands featured here. The old October birth stone, pink tourmaline, is pretty but essentially impractical, as it is quite fragile & unsuitable to cut into the consistent shapes & sizes an eternity band's gems require. In folklore, October birth stones were cherished as gemstones believed to inspire creativity in the wearers, and were given to signify hope. This conjunction of strength and value-- pink sapphires are the strongest naturally pink precious stone other than the exceptionally rare pink diamond and are much less costly-- make them the wise choice as modern October birthstones.
