Most would probably agree that physical rubies and diamonds are not a great investment but a company that has explored and found gems, is about to release results and it's share price is moving upward may be veiwed as a candidate for short term investment (prefer the word trade) because the punters in the market also think that this is worth a go and push the price higher and higher. TAW for example. Just the posibility of this company finding diamonds has pushed the price up significantly of late and a small find further again. I for one am enjoying this 'investment' in diamonds.
