Frequently asked questions
-
Where does rhodochrosite come from?
The historical and ongoing center of supply for banded "Inca rose" rhodochrosite is the Capillitas mine in Catamarca province, northern Argentina, which has been mined since pre-Columbian times. Other commercial deposits exist in Peru, the Sweet Home Mine in Colorado, South Africa, and Mexico, but Argentine material defines the variety in the bead trade. Origin should be disclosed; ask before buying if it isn't specified. -
Is rhodochrosite dyed?
No — rhodochrosite is sold natural across Dakota's catalog. The rose-pink to raspberry-red color is intrinsic to the manganese carbonate chemistry, and the stone is rarely dyed because the natural color is already what designers want. Stabilization (resin impregnation) is sometimes applied to softer or fractured rough; if a strand has been stabilized, that should be disclosed. -
How durable is rhodochrosite for jewelry?
Mohs 3.5–4 — significantly softer than most jewelry-grade gemstones. Necklaces, earrings, and bracelets are fine with reasonable care; rings are not recommended because the surface will not hold up to daily contact. Store rhodochrosite separately from harder beads to avoid scratching, and clean with a soft cloth and mild soap only — no ultrasonics, no steam, no acidic cleaners (rhodochrosite is a carbonate and reacts with acid). -
What's the difference between rhodochrosite and rhodonite?
They are different stones with similar names and overlapping pink palettes. Rhodochrosite is manganese carbonate (MnCO₃), Mohs 3.5–4, typically showing concentric pink-and-white banding. Rhodonite is manganese silicate, Mohs 5.5–6.5, typically showing pink with black manganese-oxide veining. Rhodonite is meaningfully harder and better-suited to daily wear; rhodochrosite carries the prized banding pattern but needs gentler handling. Mineral identity should be disclosed. -
What sizes and cuts does Dakota carry?
Our active rhodochrosite inventory centers on 6mm and 8mm rounds, with 3mm, 4mm, 5mm, and 10mm rounds also stocked. Round is the dominant cut; rondelle and faceted variants appear in select sizes. Full size and cut availability is filterable in the grid above; designers replenishing an existing design can confirm exact strand specifications on each listing.
