A woman commissioned me to make her a ring that was a gift from her gran. She wanted to wear it on her middle finger and wanted it to be yellow gold with a neutral colour of stone that she wouldn't tire of. After considering a few different stones, she decided to go for a marquise moonstone. Set in yellow gold it looks stunning.
Moonstone is a variety of the feldspar group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence. Adularescence is the light that appears to billow across a gem changing the stone from a pale white to a flashing blue.
