The specimen is particularly notable for the coarse grain size of the sand particles, giving them a distinctive granular texture and warm beige coloration. Their overlapping, blade-like forms create an almost sculptural appearance, with numerous intersecting surfaces and open spaces throughout the cluster. There is one spot, buried in the middle of the cluster, where I believe a single, small blade may have broken off but it is not noticeable. \u003c\/p\u003e\n\u003cp\u003eThe specimen's impressive size, complex crystal arrangement and distinctive natural texture make it an excellent display piece and a particularly interesting example of this classic American mineral occurrence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMinerals: \u003c\/strong\u003eGypsum (variety selenite) coated with coarse-grained sand\u003cbr\u003e\u003cstrong\u003eLocality:\u003c\/strong\u003e Grain Salt Plains\u003cstrong\u003e, \u003c\/strong\u003eJet, Oklahoma, USA\u003cbr\u003e\u003cstrong\u003eCrystal System: \u003c\/strong\u003eMonoclinic\u003cbr\u003e\u003cstrong\u003eMineral Class: \u003c\/strong\u003eSulfate\u003cbr\u003e\u003cstrong\u003eProvenance: \u003c\/strong\u003eEx Bill Rouslin Collection #499\u003cbr\u003e\u003cstrong\u003eDimensions: \u003c\/strong\u003e23 x 14 x 15 cm\u003c\/p\u003e","brand":"Rocky Mountain Minerals and Fossils","offers":[{"title":"Default Title","offer_id":53432844452122,"sku":null,"price":275.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6011\/1386\/files\/Selenite-Sand-Crystal-Cluster-Jet-Oklahoma-USA_06.jpg?v=1794446649","url":"https:\/\/keithrocks.ca\/products\/selenite-sand-crystals-jet-oklahoma-usa","provider":"Rocky Mountain Minerals and Fossils","version":"1.0","type":"link"}
