Disappointment in the appearance of the stone was not uncommon.

In 1852, in Amsterdam under the personal supervision of Victoria's consort, Prince Albert, and the technical direction of James Tennant, the diamond was cut from 186 1 / 16 carats ( 37. 21 g ) to its current 105. 602 carats ( 21. 61 g ) to increase its brilliance.

Albert consulted widely, took enormous pains, and spent some £ 8, 000 on the operation, which reduced the weight of the stone by a huge 42 percent — but nevertheless Albert was dissatisfied with the result.

The stone then was mounted in a brooch which Queen Victoria often wore.

It was kept at Windsor Castle rather than with the rest of the crown jewels at the Tower of London.
