Right here. Watermelon tourmaline grows with a pink center and a green rim, and it runs all through my Orenda collection on this page: 348 carats of graduated watermelon tourmaline finished in solid 18k gold, a graduated drop necklace, a spike necklace in 24k gold vermeil, stiletto earrings and marquis drops. I make every piece by hand in my Denver studio, and every piece is built once: when it sells, it's gone. The sold pieces stay up so you can see the range. Ask me about a custom piece if the one you wanted has sold.

Yes. Tourmaline is October's birthstone, along with opal, and the gem of the eighth wedding anniversary. Unlike most birthstones, it doesn't lock you into one color, so find her color first and let the stone follow: pink for warmth, green for groundedness, watermelon for the person who's always a little of everything. Every piece here is one of a kind, so no one else will wear the same one.

Yes, and that is a big part of its beauty. Tourmalines are known for their imperfections, and I actually think the stones' flaws contribute to their beauty greatly. I buy my tourmalines from vendors at the Tucson Gem Show and choose each one for its individual character rather than uniformity. In a bi-color stone the split between pink and green is different every time, and it shifts with the angle you see it from, which is why no two pieces in my Orenda collection look identical.

Yes. Tourmaline is 7 to 7.5 on the Mohs hardness scale and generally suitable for everyday wear. It stands up to light and most chemicals; heat is what can hurt it, because heat can shift the color in sensitive tourmalines. That is why I build by cold connection: every stone wired into place by hand, with no heat near the stones. Necklaces and earrings are the easiest everyday tourmaline, and my open oval statement cuff is built to sit firmly on the wrist without spinning. Just avoid hard knocks.

Gold, on every piece. Most pair 14k gold-filled wire, chain and clasps with 24k gold vermeil accents. Vermeil is a thick layer of 24-karat gold bonded over sterling silver, far more durable than standard gold plating. Where a piece demands it, I use solid gold: the 348-carat watermelon necklace has solid 18k gold beads and clasp, and one pair of chandelier earrings hangs from solid 18k gold hoops. At that scale, only solid gold reads correctly.

Warm water, a degreasing dish soap like Dawn, and a soft toothbrush. Never put your pieces in an ultrasonic cleaner: it is not safe for the stones, and steam cleaning is not recommended for tourmaline either. A Sunshine polishing cloth brightens the metal parts. Between wears, store each piece separately in an airtight bag with anti-tarnish strips, which protects the vermeil and keeps harder stones from scratching it.

Let the color do the work. A single tourmaline piece against an all-neutral outfit (black, white, cream, gray) is the simplest way to let the stone command the room. Or match it to your outfit's color family: pink tourmaline with burgundy, green with olive. For a pop, wear hot pink rubellite with a navy blazer, or watermelon tourmaline with a white linen shirt. A statement cuff pairs with a simple dress, or with stacked bangles on the opposite wrist.
