 | Some significant sales taking place already in 2019 have continued that trend. As usual it is the finest and most investment worthy stones leading the charge. A 17.43 carat Kashmir sapphire ring sold for £723,062 at the Bonhams London Jewels sale, obliterating it's pre-sale estimate of £300,000-400,000. |  |
