Larimar Crystals

Larimar is a rare blue variety of pectolite, a sodium calcium silicate found in only one place on Earth: the province of Barahona in the Dominican Republic. The blue color is caused by copper substitution within the crystal structure. Its palette ranges from white-blue to deep volcanic blue, with white pectolite patterns creating wave-like marbling reminiscent of Caribbean waters. Larimar rates 4.5–5 on the Mohs scale.

Mining is done by hand in small-scale operations that follow narrow volcanic veins in the mountainous terrain above Barahona. The deposit is geologically limited and finite — no other locality on Earth produces this material. This single-source origin combined with growing global demand makes larimar one of the rarer collectible minerals available. Specimens with the deepest blue saturation command the highest values.

Available forms include raw specimens, polished pieces, palm stones, and bracelets. For other blue minerals, see our lapis lazuli, sodalite, and angelite collections. Browse crystal jewelry for larimar pendants. For ocean-themed pieces, see crystals for bedroom. Free shipping on orders $150+.

Frequently Asked Questions

What is larimar?

Larimar is a rare blue variety of the mineral pectolite, found exclusively in the Dominican Republic. The blue color comes from copper substitution in the crystal structure. It rates 4.5–5 on the Mohs scale.

Why is larimar so rare?

Larimar is found in only one location on Earth — the mountains of Barahona province, Dominican Republic. Mining follows narrow volcanic veins by hand. The deposit is finite and geologically limited to a small area. No other source has been discovered worldwide.

Can larimar fade in sunlight?

Some larimar specimens can lighten with prolonged direct sun exposure. Darker pieces with higher copper content tend to be more color-stable. Store away from direct sunlight when not displayed. Brief exposure during normal wear is fine.

How should I care for larimar?

Larimar is soft at Mohs 4.5–5. Store separately from harder minerals. Clean with a soft damp cloth — avoid ultrasonic cleaners and harsh chemicals. Remove larimar jewelry before swimming or showering. Avoid prolonged sun exposure to preserve color.

Why does larimar look like water?

The wave-like marbling in larimar is created by alternating blue pectolite (copper-bearing) and white pectolite within the same specimen. The pattern forms naturally during crystallization and varies by specimen. The most prized pieces have deep blue with minimal white.
