This innovative design from Jessie V E London allows you to write secret messages using diamonds. Three rows of brilliant-cut diamonds are used to spell out six- or eight-character messages in braille. The bespoke braille messages are written in inverted diamonds, the pointy tips of which can be felt when running your fingers over the rows of diamonds. The messages must be short and sweet with such a tight character count, but the concept lends itself perfectly to initials, dates and names. Or for an alternative way to propose, why not use the secret diamonds to spell out “marry me”. (£3,500 for six characters, £4,000 for eight characters).
