I am Craig McGregor, and rock and mineral collector for over 40 years.  I am in Christchurch, New Zealand and welcome any inquiries about the lapidary work I do, or trading materials.

My special interests are in New Zealand and Australian materials. I have specialised in sphere making for 18 years and continue to flat lap agates, petrified wood and other interesting materials.

Petrified woods such as ferns like Milleracaulis, Osmundacaulis and Donponoxylon, araucaria and cycads from the mid Jurassic hold special fascination for me.

I have been a member of the Canterbury Mineral and Lapidary Club, www.cmlclub.org.nz, for over 40 years, and am currently on the organising committee.
