The most prevalent color in the market is dark olive green, which closely resembles peridot. Idocrase belongs to the tetragonal crystal system, typically forming short prismatic crystals. When the length of the crystal axes is equal, Idocrase can resemble other gemstones like fluorite or garnet, while the elongated prismatic crystals can appear similar to zircon or tourmaline.<\/p>\n\n<div class=\"wp-block-columns alignfull is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-container-core-column-is-layout-f7a85e60 wp-block-column-is-layout-flow\" style=\"padding-top:var(--wp--preset--spacing--80);padding-right:0;padding-bottom:var(--wp--preset--spacing--80);padding-left:0;font-size:0px;line-height:0\">\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><a href=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2024\/05\/Vesuvianite-ve013b.jpg\"><img decoding=\"async\" src=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2024\/05\/Vesuvianite-ve013b.jpg\" alt=\"Idocrase\" class=\"wp-image-38852\" style=\"width:288px;height:auto\"\/><\/a><figcaption class=\"wp-element-caption\">Idocrase<\/figcaption><\/figure>\n\n\n\n<p class=\"has-text-align-center\">(Figure 1) <sup data-fn=\"a1cfaeb8-9a85-4e7a-a83c-76ca4f6d17bd\" class=\"fn\"><a href=\"#a1cfaeb8-9a85-4e7a-a83c-76ca4f6d17bd\" id=\"a1cfaeb8-9a85-4e7a-a83c-76ca4f6d17bd-link\">1<\/a><\/sup><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading has-text-align-center\" id=\"&#x7B26;&#x5C71;&#x77F3;-idocrase\"><a href=\"https:\/\/www.google.com\/search?sca_esv=7898575184a519fd&amp;sca_upv=1&amp;q=Idocrase&amp;udm=2&amp;fbs=AEQNm0AaBOazvTRM_Uafu9eNJJzC3QMRKTS5UIeA1ZwBo3sfI5STBA5pr7fqo2I_v__3YVGutX-70hIyezlJk563Fvna8oD1sNHqlXqHEtA_5tJ6Rwz0mDcmgdsyB1mc4l91NxcAIZGPd7s98A5wzvNYvTly0TS6qmEG5rusotP6zo7iyBa9epAnif9uhh3YVuE3VunDHKzi&amp;sa=X&amp;sqi=2&amp;ved=2ahUKEwirmNSaquKGAxXflFYBHWOaDhEQtKgLegQIDRAB&amp;biw=1536&amp;bih=695&amp;dpr=1.25\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Idocrase<\/a><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"line-height:2\">Crystal system: Tetragonal System<\/li>\n\n\n\n<li style=\"line-height:2\">Hardness: 6~7<\/li>\n\n\n\n<li style=\"line-height:2\">Specific gravity: \u00b13.4<\/li>\n\n\n\n<li style=\"line-height:2\">Luster: Vitreous luster, resin luster<\/li>\n\n\n\n<li style=\"line-height:2\">Transparency: Transparent to translucent<\/li>\n\n\n\n<li style=\"line-height:2\">Color: Yellow-green-green, brown, yellow, blue, purple<\/li>\n\n\n\n<li style=\"line-height:2\">Index of refraction: 1.713~1.718<\/li>\n\n\n\n<li style=\"line-height:2\">Birefringence: 0.001~0.012<\/li>\n\n\n\n<li style=\"line-height:2\">Fluorescence: None.<\/li>\n\n\n\n<li style=\"line-height:2\">Cleavage: Imperfect cleavage.<\/li>\n\n\n\n<li style=\"line-height:2\">Characteristics: Low birefringence, medium to high refractive index<\/li>\n\n\n\n<li style=\"line-height:2\">Imitation: Glass, Soviet diamond, peridot<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n<h3 class=\"wp-block-heading\" id=\"&#x7B26;&#x5C71;&#x77F3;&#x5206;&#x985E;\"><strong>Classification of Idocrase<\/strong><\/h3>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2024\/05\/Vesuvianite-t07-71a.jpg\"><img decoding=\"async\" src=\"https:\/\/honwaygroup.com\/wp-content\/uploads\/2024\/05\/Vesuvianite-t07-71a.jpg\" alt=\"\" class=\"wp-image-38856\" style=\"width:164px;height:auto\"\/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p><\/p>\n\n\n\n<p>Californite <sup data-fn=\"74be37e0-1590-46b5-8a77-e95029c2b427\" class=\"fn\"><a href=\"#74be37e0-1590-46b5-8a77-e95029c2b427\" id=\"74be37e0-1590-46b5-8a77-e95029c2b427-link\">2<\/a><\/sup><\/p>\n\n\n\n<p>The translucent green Idocrase found in California is often marketed as &#8220;Californite&#8221;
