This is a Man Made element that sells for NEARLY $30,000,000 PER GRAM. The reason for this ultra-expensive price is its rarity as only 8 grams have ever been made since 1950 and this extra-rare metal only last around 5 years. Californium is obviously too rare for average mortals like us. Content via Discovery. All images from Wikimedia

With the rapidly expanding use of fluorescent lamps (FLs) and increasing interest in conservation and sustainable utilization of critical metals such as rare earth elements (REEs), the recovering of REEs from phosphors in waste FLs is becoming a critical environmental and economic issue. To effectively recycle REEs with metallurgical methods, mechanical activation by ball milling was ...
The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
