Tumbled Snowflake Obsidian

If you’re looking for a rock that looks like it just got caught in a midnight flurry, you’ve found it. Snowflake Obsidian is a natural volcanic glass that forms when lava cools down fast—but it wouldn’t be a Groovy favorite without a little flair. Those white "snowflakes" are actually inclusions of a mineral called Cristobalite, creating a high-contrast, monochromatic vibe that looks killer tucked into the top-dressing of your favorite Pothos or sitting on a sunny windowsill.
