The live sale will go on as planned but the saleroom will not be open to the public. Because of a pending lockdown in the U.K. due to the global coronavirus pandemic, public previews in London were moved up to the beginning of November with the last preview day being held Wednesday ahead of Thursdays lockdown. Estimates range from $1,600 to $950,000. Bids will instead be submitted by absentee means, online and by telephone. Total diamond weight is approximately 110 to 120 carats.
