Frequently asked questions

• Is Larimar a natural stone, and where does it come from?

  Larimar is the blue variety of pectolite, a sodium calcium silicate hydroxide mineral. Commercial-quality Larimar is found in exactly one place on earth: a single mountain deposit in the Barahona province of the Dominican Republic. Color ranges from white and pale sky-blue through deeper volcanic blues, sometimes with red or brown iron inclusions. Most Larimar on the bead market is sold in its natural state without dye or stabilization — ask before buying if it isn't specified. The limited single-source supply is the main driver of pricing across grades.
• How does Larimar's Mohs 4.5–5 hardness affect what I can design with it?

  At Mohs 4.5–5, Larimar is softer than quartz (7) and even softer than turquoise (5–6). It scratches and chips more easily than most beadable stones, so it belongs in pieces that don't take repeated impact. Earrings, pendants, and necklaces are the strongest use cases. Bracelets work for occasional wear but will show wear faster than agate or jasper bracelets. Avoid rings entirely. When stringing, use beading wire with soft bumpers or knot between beads to prevent bead-on-bead abrasion, especially on faceted cuts where edges are vulnerable.
• Is Larimar photosensitive, and how should finished pieces be cared for?

  Yes — Larimar's blue color can fade with prolonged sun and heat exposure, so don't display finished pieces in a sunny window or leave them in a hot car. For cleaning, use a soft dry or barely-damp cloth only. Avoid ultrasonic cleaners, steam cleaners, hot water, perfumes, hairspray, lotions, household cleaners, and any solvent. Store Larimar separately from harder stones in a soft pouch to prevent scratching. Tell finished-piece clients to put jewelry on last when dressing and remove it first when undressing — standard practice for any soft, porous-looking stone.
• What other stones get confused with Larimar in the bead trade?

  Larimar's milky blue-and-white pattern overlaps visually with several other stones. Some turquoise and amazonite can resemble lighter Larimar at a glance, and dyed howlite or magnesite is sometimes misrepresented as Larimar in low-end markets. Aquamarine occasionally gets cross-shopped on color, though aquamarine is transparent and Larimar is opaque to translucent. The clearest tells for genuine Larimar are the characteristic volcanic swirl pattern, occasional red iron inclusions, and the cool feel of pectolite. Single-source Dominican origin also means Larimar carries a price floor that dyed substitutes don't.
• Which Larimar cuts and sizes work best for which projects?

  Smaller rounds and rondelles in 3mm–6mm are the workhorse sizes for delicate necklaces, layering strands, and earring drops where the pattern reads as a soft blue wash. Larger 8mm rounds and pebble/nugget cuts show off individual color patterning — better for focal beads and statement pendants where each bead is visible. Faceted rondelles and microfaceted rounds add light reflection but expose more edges to chipping, so reserve them for low-impact wear. Heishi and tyre cuts string flat and pair well with metal spacers and other soft pastels like pink opal or moonstone.
