Just in time for her son's first birthday, Oscar-winning singer Adele has commissioned a bespoke gold necklace featuring the word Mummy in her own handwriting from a little-known Brighton jeweller.

The star, who lives in Hove and won an Oscar earlier this year for her Bond theme Skyfall, showed off the necklace and a gold bracelet in a photo she posted on Twitter close to the birthday of her son, Angelo James, with boyfriend Simon Konecki.

In a tweet, Adele revealed that jeweller Cherise Blyth, who runs her business La Verne UK from a studio at her home in Brighton, is a pal.

She wrote: “Look at these stunning pieces my friend @LA_VERNEUK made me! That's my handwriting! So personal, so clever x.”

But both Adele, currently recording her third album, and Ms Blyth remained tightlipped about their friendship. A spokeswoman for Adele declined to comment on the singer's behalf while Ms Blyth refused to reveal details about her famous client.

However, Ms Blyth did confirm the gold handwriting on the necklace is Adele's. She told The Argus: “I developed the technique myself so the gold writing is unique and individual each time - even a second copy of the same handwriting would be different.

"The client handwrites the word and I take a print and put it straight onto metal. Then I saw it out of its frame of metal and work on it in more detail.”

The designer began work as a jeweller five years ago and launched La Verne UK in January.
