The stamp highlights a specimen from Ouegoa, a locality in the north of New Caledonia, reflecting the territory\u2019s broader geological richness. As a mineralogical subject, chalcanthite is significant both scientifically and visually, making this issue a strong thematic fit for a mineral\u2011focused philatelic collection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Stamp Details<\/strong><\/h2>\n\n\n\n<p><strong>Country:<\/strong> New Caledonia <\/p>\n\n\n\n<p><strong>Year of Issue:<\/strong> 1982 <\/p>\n\n\n\n<p><strong>Denomination:<\/strong> 15f <\/p>\n\n\n\n<p><strong>Subject:<\/strong> Chalcanthite (from Ouegoa) <\/p>\n\n\n\n<p><strong>Theme:<\/strong> Minerals <\/p>\n\n\n\n<p><strong>Set Name:<\/strong> Single\u2011issue release; not part of a multi\u2011stamp set<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Catalogue Notes<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Issued under \u201cNouvelle\u2011Cal\u00e9donie et D\u00e9pendances\u201d, the historical postal authority used before the modern \u201cNew Caledonia\u201d designation.<\/li>\n\n\n\n<li>The mineral depiction is unusually accurate for the period, showing chalcanthite\u2019s characteristic saturated blue colour.<\/li>\n\n\n\n<li>Postmark present on this copy indicates postal use.<\/li>\n\n\n\n<li>No major colour varieties or reprints are known for this issue.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This 1982 issue from Nouvelle\u2011Cal\u00e9donie et D\u00e9pendances features a vivid depiction of chalcanthite, a striking blue copper sulfate mineral known&hellip;<\/p>\n","protected":false},"author":1,"featured_media":963,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[355,332,362],"tags":[360],"class_list":["post-962","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-new-caledonia","category-oceania","category-theme-minerals","tag-chalcanthite"],"jetpack_featured_media_url":"https:\/\/stamps.31pendleton.com\/wp-content\/uploads\/2026\/04\/New-Caledonia-1982-Chalcanthite-15f.jpg","_links":{"self":[{"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/posts\/962","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=962"}],"version-history":[{"count":2,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/posts\/962\/revisions"}],"predecessor-version":[{"id":968,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/posts\/962\/revisions\/968"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=\/wp\/v2\/media\/963"}],"wp:attachment":[{"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=962"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=962"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stamps.31pendleton.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
