Opal takes its name from the Sanskrit upala, meaning precious stone, and has symbolized hope and creativity. Tourmaline, from the Sinhalese turmali, meaning mixed, comes in every color. Pink topaz is tied to love and warmth, and moonstone to intuition and new beginnings.

October’s stones span the heart and crown chakras, tied to love, creativity, and intuition. Opal and moonstone are believed to spark imagination and inner knowing, while tourmaline and pink topaz support balance and warmth.

Opal (Mohs 5.5 to 6.5) is softer and needs more careful wear but offers a unique play-of-color no other gemstone can match. Both make meaningful October birthday gifts.
