Hi Karen,
I have a little shed that I started carving in, but as I got more tools, hammers, and other chisels for larger indoor sculpture it started to get a little small. So I work outside weather permitting, for large pieces, on some gravel hard standing for the car at the back of the house. Then of course more things were being stored so now it is just a store. I have been carving these small pieces of stone on a small garden table as long as it is dry and not too cold.
I really do not know much about jade and could not find any in the UK. The jade I have been carving I have bought in slab form through ebay coming from the USA sourced from Guatemala. It is not what real aficionados or the Chinese want, the main reason I can afford even with import charges. I have seen jade on ebay being sold from China even in pebble form with a polished window but felt very unsure about buying any. Perhaps others might have done so and please tell me about it.
As the jade of pre-Columbian Americas was my inspiration,

I think the mottled lavender is absolutely lovely stuff with a beautiful colour and silky smooth in the hand. I prefer it over green and the more expensive blue green. It is a funny thing the values put on some art and other objects. The people with the money drive the market and set the ideas as to what is perceived as the best or most desirable but what if their taste is questionable? I do not know about stones and jade but I think Saatchi is a good example of money becoming the abettor and elevator of questionable taste and aesthetics.
