While these gemstones can be gifted as per zodiac signs, the conventional notion of gifting a birthstone is to mark the birth month. Still, if you are confused regarding which one to choose, you can go by the zodiac sign to avoid the confusion or the week in which you met your soul mate born in October.
Opal has milky and multiple colored glow as well as fire. The October birthstone has hues that range across the rainbow color spectrum and is believed to represent purity as well as hope. Similar to opal, even tourmaline is appreciated for its plethora of colors and symbolism. As per an ancient legend, the October birthstone traveled along the rainbow and collected its colors, which is why the gem is found in an array of hues. When it comes to symbolism, tourmaline is believed to strengthen the body, mind, and soul.
If you are planning to gift someone born in October a tourmaline birthstone ring, it can be a wise choice as the ring is available in vintage-inspired styles and with accent diamonds. For instance, think of a tourmaline and diamond ring that offers a throwback to the jewelry of the Victorian period. The same can be said of opal rings, which can be considered as a gift choice if you are going by the special occasion.
