The Meghan Markle Effect: The selling power of Meghan Markle

Before she was royalty, Meghan Markle was just like us and now a cheap ring she wore once keeps selling out.

The 36-year-old posted the photo of herself on Instagram wearing the ring back when she had social media and the under $50 gold wraparound ring sold out in minutes, reports The Daily Mail.

Finally, BaubleBar rereleased the $45 ring after it was sold out for quite a long time but since being restocked this week, it is already selling out quickly with some sizes having to be pre-ordered.

The Peacemaker Ring is not only enticing because it's under $50 you also get free shipping and it's actually quite pretty and looks like an expensive piece of jewelry.

She posted the photo of herself awhile back wearing the 14K gold plated brass hypo-allergenic leaf ring with the caption, 'My sweet Olivia Palermo - thank you for all the baubles.

Apparently, the ring was one of Meghan's favourites and we could see why as it is adjustable which makes it fit nicer and it is completely covered in crystals, wrapping around two fingers and drooping down the entire hand.

The multi-finger vine ring was inspired by nature and the bauble delicately wraps around the hand which Meghan showed off in her selfie.

Meghan's sultry selfie sees her wearing a black wide-brimmed hat while resting her fingers against her mouth, showing off the ring and smiling.

While fans of the ring who have been waiting months for its return were ecstatic to hear it was back in stock, it is quickly running out.

The size six/seven ring is already out of stock and only available for pre-order which if ordered today ships by March 26, 2018.

Although the bestselling ring is out in some sizes, the seven/eight is still in stock but not for long as the rings are flying off the shelves.

Meghan's cheap little bauble is a far cry from her royal engagement ring from Prince Harry, 33, which features two stones on either side of the ring which came from Princess Diana's personal collection, with a giant diamond in the center.

The large diamond in the center of the ring is from Botswana which holds a special place in the couple's heart.

While customers trying to get a hold of the $45 ring wait patiently for a restock, this isn't the first time the Meghan effect was in full swing.

Everything she wears pretty much sells out almost instantly and just recently her $584 Strathberry purse sold out in a mere 11 minutes and is still not restocked.
