Rolling Hills Dolomite—also known as Wave Dolomite or Desert Sandstorm—is a distinctive sedimentary carbonate rock featuring wavelike banded patterns in warm desert hues like tan, pink, and red.

Key Properties

• Origin: Mined almost exclusively in Chihuahua, Mexico.
• Appearance: Striking, compressed sedimentary layers that create a flowing, rolling wave visual. It is speculated—though unconfirmed—to be an ancient stromatolite or fossilized algae formation.
• Composition: Calcium magnesium carbonate with mineral impurities like calcite, quartz, and feldspar that accentuate its contrasting color layers.
• Hardness: A soft stone, measuring about 3.5 to 4 on the Mohs scale, meaning it requires careful handling when used in jewelry.

This is what Ondrea from WA had to say about our gemstone rough: Exactly as shown in the pictures; carefully packed and shipped quickly; highly recommend this seller!

Safety Advisory (California Proposition 65):

While completely safe to display on a shelf or wear as finished pieces, many raw mineral specimens naturally contain toxic elements, heavy metals, or glass-like structures (such as copper, arsenic, lead, or silica). To ensure your safety, please follow these responsible ownership and lapidary protocols:

• Basic Handling: Always wash your hands immediately after touching raw minerals and never ingest minerals.

• Lapidary Safety: When cutting or drilling, always use specialized safety equipment, including wet-cutting machinery, proper ventilation, and appropriate respirators or masks to avoid inhaling toxic dust or fumes.
