During a visit to Canada in 1901 the Prince and Princess of Wales who later became King George V and Queen Mary fell in love with sodalite and subsequently had 130y tons shipped to the UK. It's widely reported the stone was used to decorate their home which was Marlborough House located on Pall Mall. The Princess also presented her husband with a letter opener featuring a sodalite handle and gold blade.
These two beautiful pieces of sodalite are being sold seperately. The weight and size of each piece can be found in the adjacent dropdown list. The sodalite slice on the left in both photos is number 1.
