October - Opal / Tourmaline

October Birthstone: Opal & Tourmaline

Opal is one of October’s birthstones, admired for its unique play-of-color—flashes of vibrant hues that shift with movement and light. Each opal is truly one of a kind, with patterns and color combinations that make every stone completely unique.

Tourmaline, the second October birthstone, is known for its incredible range of colors. From vivid pinks and greens to bi-color and watermelon varieties, tourmaline offers exceptional diversity and character, making it a favorite for distinctive jewelry.

At French Cut Gems, we specialize in natural colored gemstones selected for their individuality, color, and character. We focus on sourcing stones with strong visual presence and unique qualities rather than maintaining large inventory.

Below is a selection of available gemstones that can be used to create a one-of-a-kind piece. Each stone is thoughtfully handpicked for its natural beauty.
