Los Angeles:
Olivier Martinez reportedly took an "alchemy test" to help with the design of Halle Berry's engagement ring.
The 46-year-old actor was apparently ordered to take the 500-year-old mystical quiz by Paris-based jeweller Robert Mazlo, who he turned to to create the yellow gold and emerald ring.
According to a source, Olivier had to answer seven questions about his Dark Tides co-star's favourite shapes, colours, numbers and signs, which Robert "decoded" and used to perfect the ring.
The insider told US Weekly: "Olivier was absolutely delighted with the result."
It is not yet known when or where Olivier and 45-year-old Halle - who has daughter Nahla, three, with ex-boyfriend Gabriel Aubry and was previously married to baseball player David Justice and singer Eric Benet - will tie the knot.
However, his home county of France is said to be in the frame.
The source added: "[Plans are] not yet finalised, [but there's a] very good chance it would be in Paris. It will be first time round for Olivier ... he would love it to be in his home city - the city he knows and loves."
