1. The Spencer tiara

Lady Diana Spencer wore this piece as her “something borrowed” on her July 29, 1981, wedding day, and also for the nuptials of her older sisters, Lady Sarah McCorquodale and Lady Jane Fellowes.

Garrard, who is the royal family’s jeweller, designed the floral and scroll motif diamond tiara around a wedding gift that Lady Sarah Spencer gave to Diana’s grandmother Lady Cynthia Hamilton when she married Viscount Althorp in 1919. Diana was pictured wearing it at a Claridge’s banquet in 1988 and again when she saw the English National Ballet in Budapest in 1992.

Princess Charlotte is reportedly aware of the tiara as she has seen pictures of her “Granny Diana” wearing it and she can’t wait to try it on, according to Australia’s New Idea magazine. Future king William is said to be trying to secure the heirloom from Diana’s younger brother. “William is quite aware the earl has daughters of his own, but the two have agreed that Diana’s iconic piece belongs to her first granddaughter,” a source told GoodToKnow.

2. The pearl choker

Diana’s triple-strand pearl choker, with a flower-shaped clasp, is another favourite piece handed down by the Spencer family that Charlotte may look forward to inheriting one day. Diana received the necklace for her 18th birthday – a tradition in the Spencer family as both of her sisters got similar necklaces. She wore it at Trooping the Colour in 1988 when she stood on the balcony of Buckingham Palace holding a young Prince Harry.

3. The floral pearl earrings

After her wedding to Charles, the Emir of Qatar gave Diana a set of pearl drop earrings containing a white flower made from diamonds. Diana wore these throughout her marriage, including when she was pregnant with Charlotte’s father Prince William, and after her divorce. In fact, just two months before she died, she was pictured wearing them during a private viewing at Christie’s.

4. The gold charm bracelet

Charlotte may have some competition from her cousin Lilibet for this bracelet that Charles gave to Diana when they tied the knot. Extra charms were added to mark special occasions, starting with a charm from their wedding venue, London’s St Paul’s Cathedral, on their one-year anniversary, as well as ballet shoes to represent Diana’s love of dance. When her sons were born, “W” and “H” charms were added.

5. The emerald set

Prince Charles gifted Diana with an Art Deco-style emerald bracelet when they wed, plus emerald and diamond drop earrings for her 22nd birthday. Diana didn’t like emeralds but wore them often to match emerald pieces loaned to her by the queen and gifts from leaders of other countries. The set has not been worn by Kate Middleton or Meghan Markle yet so could also be locked away for Charlotte one day.
