The replicas of Kate Middleton's engagement ring were ready to hit the store and be sold to the public but at the last minute, the reproductions disappeared from the Royal gift shop.

The replicas of the Duchess of Cambridge's engagement ring, which is worth £1M and encrusted with a rectangular sapphire stone surrounded with small diamonds, were already manufactured but were pulled out from retail, reported the Daily Mail.

According to International Business Times, the manufacturer, Bill Skinner, was left wondering as to why the ring was pulled out from sale while the necklace and the pair of earrings which go with it, will still be sold at £14.99 and £29.99, respectively.

The manufacturer said, "We do make the ring but they don't want us to supply it to the gift shop."

The jewelry item would have been a part of the Princess Diana Jewelry Collection of souvenirs sold at the Royal gift shop. The Daily Mail report said that it might have been Kate Middleton herself who banned the sale of the replicas.

 A Royal source claimed that the Duchess may have stopped the selling because her engagement ring "has such deep personal significance for her" and Prince William, her husband. The source also stated that it is understandable that the 33-year-old Kate's decided to veto the selling of the ring. The Duchess may not want that other people would be wearing the same ring she wears every day.

The engagement ring was given by Prince William to Kate when he proposed. It was originally owned by Princess Diana and according to the Prince, the ring held a special place in his heart. Giving the ring to Middleton is Prince William's way to make sure that his mother was a part of the engagement.

The £28,000 blue sapphire ring was chosen by Princess Diana during her engagement to Prince Charles.
