At DEMA Show 2025, jewelry brand The Invasive Fin is catching eyes and saving reefs.
Founded by Brittany Diorio in St. Croix, USVI, the brand transforms fins from invasive lionfish into sleek, ocean-inspired jewelry and accessories.
Every piece features real lionfish fins — tail, pectoral or pelvic — giving each its own natural pattern and color. The designs range from earrings and necklaces to bottle-opener keychains, cufflinks and even golf ball markers.
Crafted with stainless steel, the jewelry doesn’t scratch easily, is lightweight, hypoallergenic, durable and dive-friendly.
Prices start at just US$7/~€6 and most items are under $60/~€52, with gemstone statement pieces like Larimar (found only in the Dominican Republic) running higher.
It’s conservation you can wear. Shop the full collection (currently 15% off for the holidays) at theinvasivefin.com.
