Hello, and thank you for reading!

This is my personal page on mindat, and I will update this from time to time to explain a bit more about me and my interests. As you probably know, I created mindat.org. It started as a personal PC database that I wrote from scratch - work I started on Christmas Day 1993. The first website version of mindat.org went live in October 2000 - and it has grown phenomenally ever since - thanks to the huge efforts of everyone who contributes.

My first specimen was this pebble containing some very rough Quartz crystals, from Tintagel in Cornwall, which I found when I was 6 years old in the summer of 1976. It was a family holiday to Cornwall, we were staying in a bungalow in the village of Egloshayle, near Wadebridge. Looking at the specimen more recently, I noticed it had dozens of tiny but perfect Anatase crystals throughout it! Here is a macro photo taken by my sister of one of these sub-millimetre crystals.
