Larimar is a rare blue variety of pectolite, a sodium calcium silicate, found almost exclusively in the Dominican Republic. It is characterized by its sky-blue to greenish-blue color, often arranged in cloud-like or wave-like patterns with white marbling. With Mohs hardness around 4.5–5 and a fibrous, sometimes porous structure, it is softer than many traditional gemstones and best suited to pendants, earrings and carefully worn rings.

Value Drivers
Carat weight matters primarily for larger cabochons that showcase broad, uninterrupted areas of vivid blue and attractive patterning. Smaller pieces and chips are common, but large, fine-quality cabochons with intense color and minimal fractures command premiums.
Color is the principal value driver. Top-quality larimar displays a rich, saturated sky-blue or slightly greenish-blue with strong contrast between blue fields and white marbling, evoking tropical seas. Pale, grayish or muddy-toned material is significantly less valuable.
Larimar is opaque to translucent; 'clarity' refers to structural integrity and visual cleanliness. Fine material is relatively compact with few open pits, voids or brown inclusions. Excessive fracturing, heavy porosity or large, distracting matrix inclusions lower both durability and value.
Larimar is almost always cut as cabochons, beads and freeform shapes. Effective cutting orients the best color and pattern on the face and avoids weak or chalky zones. A smooth, high-quality polish is important, though achieving it can be challenging in more fibrous or porous pieces.
Market Dynamics
Commercial larimar comes almost entirely from a limited mining area in the Barahona region of the Dominican Republic. Production has been artisanal and subject to fluctuations based on local conditions, safety and access. While large amounts of lower-grade material exist, fine, richly colored pieces with attractive patterns are notably scarcer.
Demand is driven by tourism in the Dominican Republic, international collectors and jewelry designers who value its distinctive Caribbean aesthetic. Larimar has become a signature stone for Dominican jewelry and is increasingly recognized worldwide in artisan and mid-range markets.
Recent Trends: niche but stable collector interest, with fine, well-documented stones achieving strong prices through specialist dealers and auctions.

Insights
Larimar was reportedly rediscovered in the 1970s on Dominican beaches, with earlier local awareness but limited exploitation.
Its blue color is associated with copper and other trace elements within the pectolite structure.
Because of its relatively low hardness, larimar is prone to scratching; protective settings and careful wear are recommended, especially for rings.
High-grade larimar often shows a vivid 'swirling clouds over water' pattern, which cutters attempt to center in cabochons.
Stabilization and backing may be used on more porous or thin material intended for jewelry to improve durability.
Larimar is sometimes mis-labeled or confused with dyed howlite or other blue stones; its distinctive patterns and locality associations help with identification.
