If you look at a modern Great White shark tooth, it’s a brilliant, pearly white. But if you browse the collection at Stones & Bones, you’ll see Megalodon teeth in deep charcoals, rusty reds, "bone" tans, and even rare "gunmetal" blues. If they all belonged to the same species, why do they look so different? The answer isn't in the shark—it’s in the dirt. It’s All About Permineralization When a Megalodon died millions of years ago, its teeth fell to the ocean floor and were quickly covered by sediment (sand, silt, or clay). Over eons, water seeped through that sediment, carrying dissolved minerals. As the organic material in the tooth slowly broke down, those minerals moved in to take its place. This process is called permineralization. Essentially, the tooth "turns to stone" using the minerals available in its specific resting place. The Color Palette of Prehistory The final color of a Megalodon tooth is a "mineral fingerprint" of the region where it was found. Here is a breakdown of the most common colors and the minerals that created them: Black & Dark Grey (Phosphate): Most teeth found in the riverbeds of South Carolina or the oceans off the coast of Wilmington are dark. This is due to high levels of phosphate in the sediment, which creates a sleek, "menacing" look. Red, Orange & Brown (Iron Oxide): If a tooth was buried in an area with high iron content (like certain pockets in the Southeast US or even parts of Mexico), the iron "rusts" inside the tooth, creating beautiful earthy tones. Tan & Cream (Calcium/Limestone): Teeth found in limestone-rich environments often retain a lighter, "bone-like" color. These are often highly sought after because they look the most like "fresh" teeth. Blue & Gunmetal (Vivianite or Rare Silica): These are the "holy grails" for many collectors. A bluish-grey tint is often caused by specific rare mineral combinations or the way light refracts through highly dense, silica-rich fossils. Does Color Affect the Price? In the fossil world, rarity drives value. While a standard black tooth is iconic and beautiful, a "Fire" (vibrant orange) or "Ash" (pure white) tooth is much harder to find. Collectors will often pay a premium for unique colors because no two teeth are ever exactly the same. The "Stones & Bones" Quality Check One thing to watch out for in the market is "painted" teeth. Some sellers will use wood stain or paint to hide repairs or make a dull tooth look vibrant. At Stones & Bones, we celebrate the natural beauty of the fossil. We don't use dyes or paints—the colors you see in our shop were created by Mother Nature over millions of years. Which color fits your collection? Whether you love the classic look of a dark "river" tooth or the rare beauty of a desert tan specimen, we have something for every shelf.
