A stunning diamond and sapphire brooch owned by Princess Margaret for most of her life is expected to sell for £18,000.
The beautiful piece of jewellery was owned by the Queen's sister from at least 1948 up until her death in 2002.
The early Art Deco pavé-set diamond bow was made in about 1920 and is about 2 inches wide.
Although it is an exquisite piece, it is the fact it belonged to the princess that quadruples the value.
It will be sold by Woolley & Wallis in Salisbury, Wiltshire, on April 28.
