Perhaps the most famous blue sapphire is the one that Diana, Princess of Wales, had in her engagement ring, which is now, of course, worn by the Duchess of Cambridge. The colour of this particular sapphire is almost synonymous with blue sapphires, but they can vary hugely in colour from icy greyish blue, cornflower, indigo and blackish blue and every shade in between.
We recommend cleaning your sapphires with a mild soapy solution and a soft brush or toothbrush, and drying with a soft cloth. We always recommend storing your jewellery carefully to avoid knocks and abrasion.
Sapphires are the birthstone for September, and the traditional gift for a 45th wedding anniversary.
