- ‘I also want some aqua aura as I'm drawn to it every time I see it, and some opal aura, I've only seen it once but I really liked it.’
- ‘I'd love to buy him some aqua aura but the bank balance won't go that far!’
- ‘From memory I was using a 1kg bag of gem grade rose quartz, a dakini stone, a lump of smoky quartz, a shiva lingham, some aqua-aura, 9 lumps of black tourmaline (in a wheel!) and about 20 other bits and bobs on the shelf (including some fair sized chunks of clear quartz) that were obviously contributing to the affair.’
