Smooth pearls in the shape of orbs and ovals are usually created by bivalves, like mussels, in pearl farms. As with all gems, the less blemishes they have, the more valuable they are. (Chip Clark, Smithsonian)

The True Story Behind How Pearls Are Made

Learn about how mollusks create these shiny gems and how that biological process could change as Earth’s waters warm

From forests to fish to flakes of snow, the science behind ice cream reaches beyond the cone. (Taryn Ellio)

The Strangely Scientific Endeavor of Making Ice Cream

Zircons are the oldest minerals in the world and come in colors like the rich blue above. Researchers have now used these gemstones to identify when modern plate tectonics began. (Ken Larsen)

New Study on Zircons Finds Plate Tectonics Began 3.6 Billion Years Ago

Many organisms like coral — and even people — create their own minerals to perform basic life functions. Geologists can study these biominerals to learn more about Earth. (Donald E. Hurlbert, Smithsonian)

How Biominerals are Stepping Stones for Climate Change Research

The National Museum of Natural History’s 146 million objects and specimens are studied by researchers worldwide who are looking to understand all aspects of the natural world. (Chip Clark, Smithsonian)

How Museum Collections Advance Knowledge of Human Health

Dom Pedro aquamarine was cut from a 100-pound crystal that was mined in the late 1980s. It weighs around 4.6 pounds, making it one of the largest aquamarine gemstones in the world. (Donald E. Hurlbert, Smithsonian)

How the Pandemic Changed Scientific Exploration

This is a giant spindle magnetofossil, created by a mysterious creature over 50 million years ago. So far, the iron fossils have only been found during two periods of intense global warming. (Kenneth Livi, Courtney Wagner, and Ioan Lascu)

New Way to Study Magnetic Fossils Could Help Unearth Their Origins

A meteorite in the process of being recovered by volunteers in the Antarctic Search for Meteorites program. The shiny fusion crust on this meteorite suggests it may be an achondrite. (ANSMET)

What Antarctic Meteorites Tell Us About Earth’s Origins

The original photos from late 1800s by famous snowflake photographer Wilson “Snowflake” Bentley, are stored in the Smithsonian Archives. His pictures were instrumental in helping scientists examine snow’s crystalline properties. (Erin Malsbury, Smithsonian Open Access, Wilson A. Bentley)

Why Scientists Find Snowflakes Cool

The Hope Diamond came to the Smithsonian’s National Museum of Natural History in 1958. Since then, museum scientists have uncovered a lot about the diamond’s intriguing past. (Dane A. Penland, Smithsonian)

Get to Know the Hope Diamond’s Keeper

Bennu is shaped like a three-dimensional diamond and seemingly smooth from far away. OSIRIS-REx is in the foreground of this artist’s replication. The spacecraft will gather a sample from Bennu next week. (NASA/Goddard/University of Arizona)
