An official range of Royal wedding china to mark the marriage of Prince William and Kate Middleton has gone on sale.

The three pieces - a tankard, plate and pill box - by the Royal Collection have been personally approved by the Prince and his fiancee.

Handcrafted in English fine bone china and featuring 22-carat gold, each item has been decorated with the couple's entwined initials.

A spokeswoman for the Royal Collection said its staff had been employed flat out since the engagement was announced on November 16.

The china has been created by Royal Collection designers and is handmade exclusively for the organisation in Stoke-on-Trent using methods that have remained unchanged for 250 years.

The spokeswoman said how each item was individually decorated and then embellished with several layers of burnished gold and platinum before a final layer of gilding in 22-carat gold is applied by hand.

All pieces come in a presentation box and are wrapped in white tissue paper printed with designs inspired by the wall hangings in Clarence House.

The tankard costs £35, the eight-inch plate £40 and pill box £25.

They are available from the Royal Collection website and its shops at Buckingham Palace, Windsor Castle and the Palace of Holyroodhouse, and will also be sold at Balmoral, Highgrove and Sandringham.

All profits from the sale of the Royal Wedding range are dedicated to the Royal Collection Trust.
