October gets opal, the one birthstone that changes as you move. Every opal here is lab-created, mostly on black tungsten so the color has something dark to stand against, and each ring has its own palette, from fire red and orange to teal, indigo and green.
Most are 8mm, with a couple at 6mm. See opal inlay rings for the full story behind each one, or the other months on men's birthstone rings.
Is the opal real? It is lab-created, and every listing says so in the title.
Will the stone hold up? Every inlay is sealed under a polished jewelry resin and set into comfort-fit tungsten carbide. Everyday wear and hand washing are fine; scraping against metal or stone is what to avoid. See our ring care guide.
Buying it as a gift? If you aren't sure of the size, our sizing guide shows how to find it, and size exchanges are free within 30 days.
