Minerals with character, collected with care.
NMMinerals is a Portuguese mineral showroom for collectors and crystal lovers: rare specimens, honest descriptions and pieces you will not find twice.
Our story
NMMinerals was born from a passion for minerals: the shapes, the colours and the stories each locality tells. We select, photograph and describe every specimen ourselves, from Portuguese classics to treasures from Brazil, Spain and beyond.
We share our finds in live sales on TikTok and auctions on Facebook, and now in this showroom, so you can take your time with each piece.
One of a kind
Every specimen is unique. The piece you see is the piece you receive.
Localities that matter
From Panasqueira and Aljustrel to Brazil, Spain and beyond.
Collector-minded
Weights, origins and details described honestly, so you know exactly what you are buying.
