Finding the Right Natural-specimens for You

Natural specimens turn things found in nature, such as rocks, crystals and timber, into art. Sometimes these specimens are hand-carved into sculptures. Other times, antique, new and vintage natural specimens themselves are best displayed in their most untouched state. These pieces range from Victorian-era objects to modern-day designs and include everything from sculptures made from animal horns to works in wood, either as sculptures or merely imposing and provocative chunks of driftwood.

Natural specimens serve as compelling decor in any collection or home. Just as any curious decorative object, such as an ancient scientific instrument or taxidermy mount, will draw attention to your carefully curated home library or mantel, natural specimens can spark interesting discussions about life and art. Whether it’s a piece of ancient pottery formed from natural clay, plants sculpted from metal, sculptures of animals or antique stone, they grant a window into all of nature’s wonders.

Natural specimen sculptures can complement many aesthetics. A rare geode makes a stunning centerpiece in a study or living room. Crystals and rock crystal spheres carved in the 1970s add a sense of etherealness and quiet beauty to any space.

Whatever your taste, the selection of antique, new and vintage natural specimens on 1stDibs includes precisely the right piece for your space.
