Since this is a natural product each box will be a unique mix of shapes, sizes, and colors.\u003cbr\u003e📐 Size ranges from large (3–5lb; 6–8\") down to chunky gravel (2lb bag of \u0026lt;3\" pieces). Not every piece of the gravel shows blue-green color (especially when dry), but it is heavy on nice chunky \u003cmeta charset=\"utf-8\"\u003efeldspar crystals.\u003c\/p\u003e\n\u003cp\u003e⚠️ Kino Blue is especially beautiful in water features because the color and pattern are emphasized when wet, but it is NOT a good decorative rock in aquariums or fish ponds; the high copper content means trace amounts can leach into the water, affecting the health of fish (and other critters). Similarly, Kino is an excellent choice for naturalistic cactus and succulent plantings but could affect the soil nutrient balance in soggy plantings.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eKino Blue rock is a beautiful option for natural outdoor decor, adding a southwest color palette around the home or in succulent gardens. It is a colorful granite mined north of Tucson, Arizona, at the site of a former copper mine. The rock's base is a black-and-white pepper-speckled granite with sparkling biotite flecks and large light-peach-colored feldspar crystals. Some sections are brick-red, which contrasts beautifully with vibrant blue-green mineral veins running through the material.\u003c\/p\u003e\n\u003cp\u003eCopper causes the blue-green color. Some of the hue is caused by weathering of copper content in the rock, which develops a light green-blue patina with exposure to water and air. This means the surface color can actually improve over time as the material weathers, making it an excellent decorative rock for outdoor use. (Granite does naturally decompose, so it is normal for small pieces to crumble off the edges as it weathers).\u003c\/p\u003e\n\u003cp\u003eCopper-based minerals add saturated patches of blue and green to the rock. Chrysocolla is the most common, typically a bright robin's egg blue to deep teal color. Thicker growth can appear shiny and translucent, which means the chrysocolla has silicified.\u003c\/p\u003e\n\u003cp\u003eCopper minerals can be difficult to distinguish without testing, but I have additionally observed what I believe to be malachite (deep green) with azurite (royal blue), dioptase (emerald green), conichalcite (yellow-green), and chalcopyrite (like fool's gold, but with peacock colors) in the mix. These minerals are amorphous and low-quality, though you may see some details where there are partial spheres or fibrous needles of radial growth.\u003c\/p\u003e","brand":"Pretty Ugly Things","offers":[{"title":"Default Title","offer_id":46934489825431,"sku":null,"price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/5192\/9495\/files\/2_673dfe0e-1bb9-41c9-931f-67fe11e569ba.png?v=1784326594","url":"https:\/\/prettyuglythingsaz.com\/products\/kino-blue-chrysocolla-in-granite-set-bulk-18lb-mixed-sizes","provider":"Pretty Ugly Things","version":"1.0","type":"link"}
