Olá people :-)
I am a mineral collector that lives in Barreiro city close to Lisbon in Portugal and I am an white African of Angola with 53 years.
My interest with Mineralogy began in 1972 when I was at school ( Liceu Paulo Dias de Novais ) in Luanda, Angola. It was near of Instituto de Geologia e Minas and at that time I was a frequent visitor.
The first specimen given to me was a small Quartz crystal (that I keep in my collection) which at that time fascinates me and I consider as a strong incentive to initiate my mineral collection.
I consider myself a systematic collector as I have interest in all mineral groups of the World and have preference for minerals with a good size and well crystallized.
I like self-collected Portuguese minerals and have various available specimens to exchange with some friends.
I like friendship and forthright and not like licking boots, envious and wiseacres.
