Meghan Markle sparkles, of course she does, she's gorgeous and from Hollywood. Her home town, her career to date and her ethnically mixed heritage breaks down some Chinese wall, size boundaries, when it comes to marrying a British prince. Not only that, she is engaged to marry the notoriously fun prince. The one, who both men and women over the world would profess to wanting a night out with, let alone a life.

Taking all the above into account, these two poster child millennials will bring plenty of who they are to this fairy tale occasion.

As I'm only requested to give tiara advice, I think this celebration jewel is the perfect item with which to embrace some star spangled modernity, while retaining a touch of pomp and tradition. Every detail should mean something to the couple; it will also become a transatlantic heirloom, testament to the three or possibly more continents from whence their roots came.

In the spirit of laying down some new directions, Meghan (soon to be Princess Henry of Wales) would look stunning in yellow gold, maybe with a touch of art deco in the detailing as a nod to the US, a break from the very ornate work, favoured by tiara suppliers.

The couple chose a diamond from Botswana for the engagement ring, because the country has a special place in their hearts. Even though I don't see the tiara as a extravagant embellished piece, a sprinkling of elegant baguette cut diamonds from the same source could be included, possibly a hint of colour also. The Duchess of Cambridge rocks the sapphires so maybe a few rubies or the very fashionable emerald, alternatively some less precious but equally beautiful garnets sourced from Africa, America and Britain.

The lines should be simple and the design linear and low rise rather than the high line crown styles that tiaras can easily adopt. This contemporary yet classical piece could easily be sported time and time again for some of the inevitable banquettes and state occasions sartorially required of princesses. Such a design would also show respect for, rather than compete with, the style of her future sister-in-law who after all will be the one who becomes queen.

Meghan on the other hand will be freer to perform even her most mundane royal housekeeping duties wearing her tiara if she so wishes.
