投資的話鑽石應該不保值，現在人工能合成了，隻是Debeer把著不讓流入市場

但是去年Debeer已經鬆口了，人工鑽石價格隻有天然的10%，將來隻會更低

“A 1-carat man-made diamond sells for about $4,000 and a similar natural diamond fetches roughly $8,000. De Beers new lab diamonds will sell for about $800 a carat. That’s a fifth of the price of existing man-made stones and one-tenth of the cost of buying a similar natural gem.”
