{"product_id":"pebbles-onyx-black-30-50-mm","title":"Black Onyx Pebble - 30-50 mm","description":"\u003cp\u003eThese Black Onyx Pebbles are smooth, polished chalcedony stones in a deep, even black, each one rounded into a glossy pebble. The surface takes a high polish that gives a sleek, mirror-dark finish, and the pebbles vary in size and shape across the lot. Smooth and weighty for their size, they sit well in a bowl, on a surface, or in the hand.\u003c\/p\u003e\n\u003cp\u003eBlack Onyx is traditionally associated with protection, grounding, and calm, long regarded as a steadying, centring stone. The pebbles work well grouped as a calming decorative arrangement, set out as grounding stones around a space, or kept individually as a pocket or desk piece. Its deep black colour and long protective tradition make Black Onyx a versatile, understated choice.\u003c\/p\u003e\n\u003cp\u003eEach Black Onyx pebble is natural and individual, varying in size, shape, and surface character from piece to piece.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Properties\u003c\/strong\u003e\u003cbr\u003ePrimary Focus: Protection \u0026amp; Grounding\u003cbr\u003eSecondary Focus: Calm \u0026amp; Stress Relief\u003cbr\u003eChakra Association: Root\u003cbr\u003eZodiac Sign: Leo, Capricorn\u003cbr\u003eChinese Zodiac: Rat, Ox\u003cbr\u003eRuling Planet: Saturn\u003cbr\u003eElements: Earth\u003cbr\u003eMohs Hardness: 7\u003cbr\u003eStone Family: Tectosilicate\u003cbr\u003eMaterial: Natural Black Onyx\u003cbr\u003eOrigin: Brazil\u003cbr\u003eForm: Tumbled\u003cbr\u003eFinish: Polished\u003cbr\u003eApproximate Size: 29-49 mm (1.1-1.9 inches)\u003cbr\u003eApproximate Weight: 17-60 g\u003cbr\u003eListing: Single unit\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeological Information\u003c\/strong\u003e\u003cbr\u003eBlack Onyx is a banded chalcedony, a microcrystalline quartz of silicon dioxide, with a Mohs hardness of 7. Almost all commercial Black Onyx is natural grey banded chalcedony dyed to a deep, even black using a sugar-acid or iron-nitrate process, the industry standard developed in the Idar-Oberstein agate trade from the nineteenth century onward; the resulting colour is stable and permanent. Onyx has been used since antiquity across Greek, Roman, Mesopotamian, and Egyptian cultures, carved into cameos, intaglios, and amulets, and the black variety in particular features in mourning jewellery and protective talismans. Sources for the base chalcedony include Brazil, India, and Germany.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuturaSol Standard\u003c\/strong\u003e\u003cbr\u003eEach natural stone is selected for its authenticity, geological integrity, and energetic clarity.
