The October birth stone, previously the appealing but weak pink tourmaline, gets a well timed update in the pink sapphire, a harder, more suitable gem stone to use in October birthstone eternity rings. These new October birth stones recall the dazzling, beautiful hue of the previous one while employing modern practicality. The pink variety of sapphires as October birthstones were the smart choice because sapphires are the strongest naturally pink precious stone other than the scarce pink diamonds, and have a substantially more affordable price point than the latter. October birthstone rings in legend have been seen as symbols of hope & believed to encourage creative inspiration.
