The state contains many distinct geological provinces, each with its own complicated history and associated rocks and minerals. Even before the famed gold rush, California had become famous for its high-quality gem pegmatites &ndash; most notably the tourmalines of San Diego County.<\/p>\n\n\n\n<p>The beaches all along the coast have long been favorite rockhounding destinations for their high quality specimens. California also has the significant benefit of fantastic weather nearly year-round in large portions of the state, which increases the window of opportunity for rockhounding. <\/p>\n\n\n\n<p><strong>The best places to rockhound in California include the areas around San Diego, Los Angeles, San Jose, San Francisco, Crescent City, and Eureka. The state contains thousands of rockhounding locations which include mines, quarries, ocean beaches, and stream beds. <\/strong><\/p>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-table aligncenter is-style-stripes\"><table class=\"has-background\" style=\"background-color:#e7f5fe\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">State Symbols<\/th><th class=\"has-text-align-left\" data-align=\"left\"><\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-left\" data-align=\"left\">State Mineral<\/td><td class=\"has-text-align-left\" data-align=\"left\">Gold<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">State Rock<\/td><td class=\"has-text-align-left\" data-align=\"left\">Serpentine<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">State Gemstone<\/td><td class=\"has-text-align-left\" data-align=\"left\">Benitoite<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">State Fossil<\/td><td class=\"has-text-align-left\" data-align=\"left\">Saber-toothed cat<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">California: <a href=\"https:\/\/statesymbolsusa.org\/states\/united-states\/california\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n\n\n\n<p><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"716\" src=\"https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298.jpg\" alt=\"\" class=\"wp-image-2253\" style=\"width:390px;height:260px\" srcset=\"https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298.jpg 900w, https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298-300x239.jpg 300w, https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298-768x611.jpg 768w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"900\" height=\"716\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20900%20716'%3E%3Crect%20width='900'%20height='716'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"\" class=\"wp-image-2253 eager-load\" style=\"width:390px;height:260px\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298.jpg\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298.jpg\" data-srcset=\"https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298.jpg 900w, https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298-300x239.jpg 300w, https:\/\/rockhoundresource.com\/wp-content\/uploads\/2021\/01\/rsz_dreamstime_xxl_170797298-768x611.jpg 768w\" data-svg=\"1\" data-trellis-processed=\"1\"><figcaption class=\"wp-element-caption\">Serpentine<\/figcaption><\/figure><\/div>\n\n\n<p><\/p>\n<\/div>\n<\/div>\n\n\n\n<p><strong>California contains a diverse array of rock and mineral specimens such as serpentine, benitoite, jade, agate, jasper, moonstone, quartz, epidote, and rhodonite.

However, I have compiled a list of resources here so that you may investigate and obtain permission for any locations (found here or elsewhere) for yourself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Public Land Resources<\/strong><\/h3>\n\n\n\n<p>I have written entire articles which cover the rockhounding laws and regulations for nearly every type of public land you can think of. I encourage you to check them out if you are curious about the legalities of rock and mineral collecting.<\/p>\n\n\n\n<ul>\n<li><a rel=\"noreferrer noopener\" href=\"https:\/\/rockhoundresource.com\/rock-collecting-on-public-land-laws-rules-and-etiquette\/\" target=\"_blank\">Rockhounding on Public Land: Laws and Regulations<\/a><\/li>\n\n\n\n<li><a rel=\"noreferrer noopener\" href=\"https:\/\/rockhoundresource.com\/can-you-collect-rocks-in-state-parks-all-50-states-answered\/\" target=\"_blank\">Can You Collect Rocks in State Parks?

Unfortunately for rockhounds, the law prohibits them from publishing their names or contact information online. You can get the landowner&rsquo;s name and address by visiting the county records office. <a rel=\"noreferrer noopener\" href=\"https:\/\/weleaseusa.com\/how-to-find-california-property-owners-information\/\" target=\"_blank\">This site<\/a> contains a detailed process for accessing as much information as possible through these means.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Sources &amp; Further Reading<\/strong><\/h2>\n\n\n\n<p>The locations and information contained in this article are primarily derived from academic papers, online resources, and other outside sources.
