Floral motifs aren't essential for wedding day jewelry, but most royal brides tend to style their looks with them. Luckily, they're on trend as well, and Marie Claire reports that royal experts seem to think this tiara is the front runner for Meghan's wedding day. Made in the 19th century, this tiara was given to the Queen Mother by her parents as a wedding present, before she gifted it to Queen Elizabeth II. Unlike most royal tiaras, this one has yet to make a modern-day appearance, giving Meghan Markle the chance to be the first to wear it publicly since Harry's great grandmother did. While the Spencer tiara would be the type of piece Meghan would loan for the day of and then have to immediately return to the Spencer family, the Strathmore Rose would likely be on a long-term loan to Markle, and could be a piece she would be able to wear for appearances as a Duchess, as the Duchess of Cambridge has with her heirloom loans.
