This sapphire and diamond wheat brooch is designed by Birks as an ear of wheat. The stalk is set with a circular-cut sapphire and brilliant-cut diamond. The item is 6cm long.

Princess Margaret embarked on an extensive tour of Canada in 1958, spending 31 days criss-crossing the country. She was the recipient of many gifts. One of the gifts presented to her was was the Ear of Wheat gold brooch from the Government of Saskatchewan.

The Medicine Hat News (28 July 1958) reported at the time:

"Mr. Lee let me have a peek at the presentation gift the Saskatchewan people will make to Princess Margaret. Its(sic) a brooch, the main portion of which is a gold replica of a head of wheat. At the base is a matched pair of stones, a one carat diamond and a one carat emerald."

The reporter erred in describing the second stone as an emerald, as it clearly is a sapphire as was listed in the original sale of Princess Margaret's jewellery.

This diamond and emerald heather brooch features a spray of brilliant-cut diamonds across the heather to the calibre-cut emerald stem which is 6.2cm in length. It comes with it's original fitted red leather Collingwood (Jewellers) LTD. case, the lid with applied plaque engraved 'R.M.S Edinburgh Castle Oct. 16th 1947'.

Built by Harland and Wolff of Belfast, the R.M.S Royal Mail Ship Edinburgh Castle was launched by H.R.H. The Princess Margaret on 16th October 1947. The R.M.S. Edinburgh Castle was the third Union Castle vessel, employed for the South African route, to bear this name. The first R.M.S. Edinburgh Castle was one of the earliest steamships ordered for the South African service and the second was launched from Harland and Wolff's in 1910. The launch of the third Edinburgh Castle by H.R.H. The Princess Margaret was the Princess' first important solo engagement, an occasion marked by the presentation of this gem-set spray of Scottish heather.

Thanking the builders and owners for their gift, H.R.H. The Princess Margaret replied "To christen this ship Edinburgh Castle gives me great pleasure, for it will ever be linked in my mind with that lovely city for which my affection has grown with each visit. I am also particularly pleased to think that this fine ship will eventually sail between the British Isles and South Africa. It was to South Africa that I made my first voyage earlier this year, and with many happy memories of that great country I am glad to launch a ship designed to increase the traffic and strengthen the bonds between the Union and the Mother Country"
