How much does Covellite cost?

Covellite is a copper sulfide mineral that forms in the secondary enrichment zone of copper ore deposits, where surface weathering processes concentrate copper from dispersed primary ores. Copper-bearing solutions percolating downward through oxidized rock encounter a reducing environment and precipitate covellite.

The mineral's stunning indigo blue color with iridescent purple and gold flashes makes it one of the most visually striking copper minerals. The iridescence comes from thin-film interference on its perfect basal cleavage surfaces. Freshly exposed surfaces flash with electric blue, purple, and gold colors.

Covellite was named after Niccolo Covelli, the Italian mineralogist who first described it from Vesuvius in the 1820s. Despite its beauty, it's extremely soft (Mohs 1.5) and has perfect cleavage, making it fragile and impractical for jewelry in its natural state.

Identification Guide

Covellite is identified by its deep indigo blue color with iridescent purple-gold flashes on cleavage surfaces. Its extreme softness (1.5), platy hexagonal crystal habit, and association with other copper minerals are diagnostic.

Distinguish from bornite/peacock ore (harder, different streak), chalcopyrite (brass-yellow base color), and azurite (harder, lighter blue, carbonate). Covellite's combination of deep indigo with iridescence and extreme softness is unique.

Spotting Fakes

Covellite is not commonly faked, though its iridescent quality sometimes leads to confusion with treated or acid-washed peacock ore (bornite/chalcopyrite). Natural covellite is much softer than peacock ore and has a distinctly deeper, more indigo base color. The iridescence should be visible on fresh cleavage surfaces rather than just on outer coatings.

Affiliate picks

Covellite gets imitated with glass, dyed stand-ins, and cheaper lookalikes. These four tools run the checks in the Spotting Fakes section above, so you can tell real from fake before you pay - online, at a show, or in a shop.

10x triplet jeweler's loupe$20-40
The first tool worth owning. Round gas bubbles (glass), dye pooled in cracks (dyed howlite, magnesite, agate), and flow lines are invisible to the naked eye and obvious at 10x. A triplet lens keeps the edges sharp.

Mohs hardness pick set~$40
Calibrated picks settle the cheap swaps in seconds - howlite (3.5) sold as turquoise (5-6), glass (5.5) sold as quartz (7). Faster and more accurate than the fingernail-and-knife method.

0.01g digital pocket scale~$15
Density catches what the eye misses. A glass 'quartz' weighs suspiciously light; lead-loaded plastic 'lapis' weighs suspiciously heavy. Weigh, compare to the known density, and flag the mismatch before the money leaves your hand.

365nm UV flashlight$20-30
Many stones have a distinctive fluorescence (hyalite opal, fluorite, ruby, scheelite). A longwave UV light is the fastest tiebreaker when a piece passes the other tests but still looks off.

Cultural & Metaphysical Traditions

Presented as cultural traditions, not scientific evidence

Covellite is associated with inner vision, dreamwork, and spiritual growth. Its deep indigo color connects it strongly to the third eye chakra. Practitioners use it for lucid dreaming, past-life exploration, and accessing hidden knowledge. The iridescent flashes are interpreted as glimpses of other dimensional realities.

Metaphysical and “healing” associations are cultural traditions, not medical advice or scientific fact. Crystals are not a substitute for professional medical care.

Heft test: Covellite has a specific gravity of 4.68 - noticeably heavier than quartz. You'll feel the density when you pick it up.

Care & Safety

What covellite can and cannot tolerate, based on its hardness (Mohs 1.5) and chemistry (CuS).

Can Covellite go in water?

Not recommended. At Mohs 1.5, covellite is soft enough that water can dull, etch, or degrade the surface. Clean it with a dry cloth instead.

Can Covellite go in salt water?

No. Covellite should stay away from water in general, and salt water is worse on every count: dissolved salt is corrosive while the stone is wet, and abrasive salt crystals are left behind in cracks and crevices as it dries. Salt also accelerates corrosion of copper-bearing minerals like covellite.
