Incredibly interesting article to read, thank you Mauriz. Tracking the information must have been time consuming

I am somewhat astounded by the increase in value for the citrines. But obviously the firm is willing to negotiate. What a lure to get potential customers to buy -- then they can say "I brought it for £xx. So many people wanted it, that I had to pay more than was initially asked!" Only the buyer & the firm would know the true cost.
