How much does the manufactured Ruby, Sapphire market impact that? A lot of what you see in Thailand now is manufactured.
They are two different items but neither has much value unless it’s really a remarkable natural stone. It’s actually sad to see people selling jewelry that was expensive to buy but now has little more than melt value. I advise people that, if you were investing in steel, you would buy bar stock, not Cadillacs. Likewise for gold, but Eagles or bullion, not jewelry.
