This bag contains approximately \u003cstrong\u003e100 g of raw malachite\u003c\/strong\u003e, divided into several fragments of various sizes, delivered \u003cstrong\u003ein their natural, unpolished state\u003c\/strong\u003e, just as they were extracted from the rock. Some feature rounded, mammillated surfaces, while others show clean breaks revealing successive layers of growth. A \u003cstrong\u003ecopper carbonate\u003c\/strong\u003e formed by the slow alteration of deposits, malachite has served as a pigment for painters, an adornment for artisans, and a cladding for palaces before finding its place in collectors' drawers. This generous format allows you to \u003cstrong\u003ecompare several specimens\u003c\/strong\u003e, observe the diversity of patterns with a magnifying glass, share a few stones during a workshop, or decorate a dish with a deep green \u003cstrong\u003emineral décor\u003c\/strong\u003e.

It forms near the surface, in the oxidation zone of copper deposits: rainwater, laden with carbon dioxide, seeps into the rock, dissolves some of the copper, and then redeposits it layer by layer in cracks and cavities. It is this rhythmic growth that creates the highly characteristic \u003cstrong\u003econcentric bands\u003c\/strong\u003e, alternating between light green and almost black green. Its name is said to come from the Greek \u003cem\u003emalakhê\u003c\/em\u003e, the mallow, in reference to the green of its leaves.\u003c\/p\u003e\n\n\u003cp\u003eWith a \u003cstrong\u003ehardness of 3.5 to 4 on the Mohs scale\u003c\/strong\u003e, malachite is a soft mineral: a steel blade scratches it with ease. It is, however, dense, between \u003cstrong\u003e3.6 and 4\u003c\/strong\u003e, giving it a surprising weight for its size when held in the hand. Its luster varies from silky to vitreous depending on the faces, and it reacts to acids, even diluted ones, producing a slight effervescence, like all carbonates. It is often found with azurite, its blue cousin, in the same deposits.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003ch3 class=\"aa-title\"\u003eWhy you will love it\u003c\/h3\u003e\n\n\u003cdiv class=\"aa-ben\"\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eAn inimitable green\u003c\/span\u003e\u003cspan class=\"ds\"\u003eFrom pale green to almost black forest green, each fragment offers its own range of shades and patterns.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eBands to decipher\u003c\/span\u003e\u003cspan class=\"ds\"\u003eConcentric lines, circles, undulations: the mineral's growth is directly visible on the surface of the breaks.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eThe authenticity of the raw\u003c\/span\u003e\u003cspan class=\"ds\"\u003eNo stones are polished: mammillated surfaces, edges, and irregularities remain visible, just as if they had just come from the deposit.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eSeveral specimens\u003c\/span\u003e\u003cspan class=\"ds\"\u003eThe approximately 100 g bag contains fragments of various sizes, to compare, sort, or share.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eAn educational aid\u003c\/span\u003e\u003cspan class=\"ds\"\u003eHardness, density, luster, reaction to acids: the key concepts of mineralogy gathered in a single mineral.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eA collector's piece\u003c\/span\u003e\u003cspan class=\"ds\"\u003eAn iconic copper mineral, malachite has a place in any collection of natural stones, whether for beginners or experienced collectors.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-des\"\u003e\n\n\u003cp class=\"t\"\u003eFrom copper mines to palace salons\u003c\/p\u003e\n\n\u003cdiv class=\"x\"\u003e\n\n\u003cp\u003eLong before it was a collector's item, malachite was a \u003cstrong\u003ecolor\u003c\/strong\u003e.
