A customer got in touch and asked me to make a special ring for his wife's birthday. He wanted it set with peridots and emeralds as those are their birthstones and he also wanted to add diamonds to the design. The ring is made in 18ct yellow gold and has a tiny letter hand engraved between each gemstone. The sequence of the letters carries a secret message that only they know.
When the ring was finished my customer named it the Enigma ring and encouraged me to share this design with others who wanted to have their own ring with a secret meaning.
