She stated: “The first engagement ring, given by Mark Phillips, features a cabochon cut blue sapphire of about two carats.
“Cabochon cut gems have a smooth, rounded finish and are not faceted, giving a soft, silk-like feel to the stone. The cabochon gem is framed by a cluster of three small diamonds either side totalling approx 0.2 carats, set in yellow gold.”
Princess Anne wore the ring after her engagement was announced on May 29, 1973.
The unique piece was not only stunning to look at, but came with an impressive price tag.
Anne added: “This one would be priced at £9,000. I find it an interesting design that holds a true 1970s vintage style.”
On December 12, 1992, Princess Anne tied the knot with her current husband, former Royal Navy Commander Timothy Laurence.
Princess Anne’s engagement ring from Timothy also featured a sapphire and could be worth more than double her first ring.
“The second engagement ring is from Princess Anne’s second husband, Timothy Laurence, and has a slightly smaller sapphire accompanied by two diamonds on either side,” Anne said.
The expert said: “Both Princess Anne’s engagement rings feature vivid blue sapphires. Sapphires symbolise honesty, trust and wisdom.
“They hold so much significance beyond being simple jewellery items.
“If someone is looking to create a more distinctive engagement ring, sapphires can be a good option as they are durable and are resistant to scratching.
“The blue also lends a unique look to the rings, as we can see here with Princess Anne.”

The royal line of succession – who outranks who?
The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.
It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.
Older children come before younger children. Traditionally boys came before girls, but this law was changed on 26 March 2015 before the birth of Prince William’s first child.
Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.
The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.
Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 38, his oldest son.
Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
