His Majesty hopes everyone is having a great Memorial Day weekend remembering those American soldiers who gave all so that we might live free.
KT checked these Septarian infillings with acid and they effervesce strongly so it is KT's best thought they consist of simple calcite, but it might be mangano-calcite as His Majesty has no way to test them further. These were a gift from a Castle visitor, part of an entire box of them. KT washed the larger ones and picked out these 4 for the Royal Collection for their nice bright fluorescence. They are from the Nacimiento Mine area, San Pablo, Sanoval County, New Mexico.
There are several Septarian nodules in the Royal fluorescent collection, from Utah and even Madagascar, all with calcite infillings, but none that fluoresce red orange and none as bright as these. KT has plenty, thanks to His Royal Visitor, to give away or trade, if you like.
The first picture is in natural light with a US dime for scale, the second is in LW 365nm and the third is in SW 254nm, lit by two lamps, one from the bottom of the image and the other positioned at the top.
Enjoy the pictures!
