We’re always keeping a close eye on the stunning outfits the likes of Meghan Markle and Kate Middleton wear during their high-profile public outings.
Recently, the future sisters-in-law even stepped out together wearing the exact same shoes.
And to compliment Prince William’s wife and Prince Harry’s partner’s amazing wardrobe, the royals own a collection of stunning jewellery, too.
But according to one expert, there’s one jewellery item the royals steer clear of completely.
Speaking to the Express.co.uk, Grant Mobley — a gemologist and Director at Pluczenik — said: “One of the many amazing things about diamonds is that they not only have the ability to maintain their value, but they very often increase in value over time.
“This is one of the many attributes that makes real diamonds different from the factory-made diamonds that have recently been introduced to the market.
“If the ring featured a factory-made diamond (which is preposterous as members of the Royal family would never wear synthetic diamonds!) but say, hypothetically, that it did, it would be worth absolutely nothing now.”
But luckily for the royals, many of them already have a vast collection of diamonds.
Princess Diana, in particular, owned many beautiful jewels which her daughter-in-laws have gone on the inherit.
In a letter, the late princess wrote: “I would like you to allocate all my jewellery to the share to be held by my sons, so that their wives may, in due course, have it or use it.
“I leave the exact division of the jewellery to your discretion.”
Kate of course wears Diana’s engagement ring, which was consist of diamonds and sapphires.
Meanwhile Harry, 33, took diamonds from his mother’s collection to create a bespoke ring for his future wife.
In fact, the trio diamond yellow gold ring he put together for Meghan has inspired others to mimic the style.
