Is it better to buy loose stones or finished jewellery?

Getting loose stones is noticeably better for investing, for an accurate valuation, and even for negotiating the price, while finished jewellery is often best for tourists who want something immediate and wearable as a keepsake, without having to track down a jeweller back home or later.

When a stone is loose, a gemmologist can assess its real carat weight with precision, check for concealed inclusions, and confirm how well the cut was shaped. Once the stone is fixed into a gold or platinum setting, the metal may conceal deeper flaws, dull the visibility of poor colour zoning, and it becomes difficult to estimate the weight properly.
