Serandite
Na(Mn2+,Ca)2Si3O8(OH)
Serandite is a silicate mineral recognized among collectors for its crystal form and distribution.
Serandite is a sodium-manganese-calcium inosilicate, one of the most sought-after collector species for its glowing salmon-pink to orange colour and sharp crystals.
The Mont Saint-Hilaire connection
Mont Saint-Hilaire in Quebec is a major locality, producing lustrous pink serandite — often with white analcime and black aegirine, a classic colour contrast.
What collectors look for
Sharp pink serandite crystals, especially the serandite–analcime–aegirine combinations, are the signature pieces.
