Up for sale is an ultra-rare, museum-quality piece of genuine, surf-tumbled Neodymium Sea Glass. Weighing exactly 2.53 grams (approx. 12.65 carats), this thick, jewelry-grade nugget is a true "Holy Grail" find for serious beachcombing collectors and artisan jewelers alike.
**Key Features & Rarity:**
* **Alexandrite-Like Color Shift:** Infused with vintage neodymium oxide, this piece features a magical, light-reactive color transition. It shifts from a soft, delicate lavender/lilac in daylight and incandescent light to a cool, icy periwinkle or steel blue under standard fluorescent light.
* **Antique "Seed" Bubbles:** As shown in the backlit photos, this chunk is densely packed with gorgeous, frozen-in-time internal air bubbles—a textbook hallmark of mid-century or earlier artisan glass manufacturing techniques.
* **Premium Jewelry-Grade Shape:** Naturally rounded, fully frosted, and exceptionally thick. It features zero harsh edges or fresh chips, making it an incredible specimen for a custom statement ring, wire wrapping, or a high-end cabinet display.
