These factors affect how light is absorbed and reflected, producing the characteristic green-blue appearance.\u003c\/p\u003e\n\u003cp\u003eUnlike quartz, feldspar minerals show cleavage planes, which can sometimes be visible as linear internal features or reflective surfaces.\u003c\/p\u003e\n\u003cp\u003eCondition\u003c\/p\u003e\n\u003cp\u003e• Smooth polished finish\u003c\/p\u003e\n\u003cp\u003e• Even shape and symmetry\u003c\/p\u003e\n\u003cp\u003e• Natural internal textures present\u003c\/p\u003e\n\u003cp\u003e• Minor inclusions typical of material\u003c\/p\u003e\n\u003cp\u003e• No major damage observed\u003c\/p\u003e\n\u003cp\u003eCare Instructions\u003c\/p\u003e\n\u003cp\u003e• Mohs hardness: ~6–6.5\u003c\/p\u003e\n\u003cp\u003e• Avoid drops (cleavage present)\u003c\/p\u003e\n\u003cp\u003e• Clean with a soft cloth\u003c\/p\u003e\n\u003cp\u003e• Avoid prolonged water exposure\u003c\/p\u003e\n\u003cp\u003e• Store separately to prevent scratches\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53820254781781,"sku":null,"price":4.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_50613ba7-d775-413e-9014-2f13a8ee2b5a.jpg?v=1777899263","url":"https:\/\/crystalballerz.co.uk\/products\/amazonite-heart-1","provider":"Crystal Ballerz","version":"1.0","type":"link"}
