Perettiite-(Y) is a complex silicate–borate mineral with the formula Y2Mn4FeSi2B8O24.[3] It was first discovered in 2015 by Adolf Peretti of the Gemresearch Swisslab (GRS). It was found as inclusions in a phenakite crystal from Mogok, Myanmar.[5]
Perettiite-(Y) was approved for IMA (International Mineralogical Association) status in 2015.
