Gem-A Corporate Member We think the photos are totally accurate with the color. See the lovely dendrites - proving it is totally natural and untreated. A beautiful gemstone - please see the video. A beautiful unusual gemstone. Please note a 55ct piece of genuine Hemimorphite sold at Auction for $5000 plus hammer fee and sales tax. We managed to find some of this rare gemstone on our last buying trip and we couldn’t quite believe our luck. Grab it as we wont get it again! Hemimorphite is a rare gem quality form of zinc silicate. Hemimorphite is very closely associated with Smithsonite, another rare collector’s gem. For many years, hemimorphite and smithsonite were both classed together another gemstone called calamine because of the similarity. In 1803 it was discovered to be two different minerals by mineralogist, James Smithson (of the Smithsonian Institute). Chemical Formula: Zn4Si2O7(OH)2•H2O - Hydrous basic zinc silicate |
