Handmade ring with a rectangular larimar cabochon from the Dominican Republic, hand-set in black copper. The rectilinear geometry of the cabochon creates a deliberate contrast with the organic veins of the mineral, framed in an architectural wire design on a dark background. Unique piece.

This Specific Piece
The rectangular shape of the cabochon is unusual for larimar — most sources prefer oval or freeform shapes. A well-cut rectangle requires greater lapidary control to maintain proportions within the available material. The result is a more architectural than organic profile, without losing the natural character of the mineral.
The black (oxidized) copper provides a sober background that highlights the blue of the larimar without adding metallic warmth that would compete with its cool tones. The cool-warm contrast is completely resolved in favor of the stone.
Larimar in Lapidary Tradition
Larimar is volcanic blue pectolite, the only mineral of its color with a single worldwide deposit in the Dominican Republic. Discovered in 1974, its name combines "Larissa" (the name of geologist Miguel Méndez's daughter) with mar (sea), evoking the color of the Caribbean. Its blue comes from the substitution of calcium by copper in the silicate structure — an extraordinarily specific geological process that explains its geographical exclusivity. In crystal tradition, larimar is associated with serenity and peaceful communication.

Frequently Asked Questions
Why is larimar so rare?
All worldwide production comes from a single deposit in the Central Mountain Range of the Dominican Republic. The geological combination that produces blue pectolite has not been found anywhere else on the planet.
What is the hardness of larimar?
Mohs 4.5-5. One of the most delicate minerals in jewelry. Avoid bumps, scratches, soaps, and prolonged contact with water. Store in a separate case to protect it.
Does the rectangular shape affect durability?
The corners of the cabochon are the most vulnerable points to impact. The setting partially protects them, but it is recommended to remove the ring during manual activities.
Is the stone dyed or treated?
No detectable treatment. The blue is the natural color of the mineral. No formal gemological certification; statement based on lapidary observation.
How do I care for this ring?
Dry cloth for the stone; black copper can be polished with microfiber. Do not submerge. Avoid cosmetics and prolonged sweat on the stone. Guide in care for your jewelry.
