Sophia Hersh is a jeweller, who knew Helen Bailey because in June 2014 Helen wanted an engagement ring model she had previously created. Julia tells jurors: “We created the original ring from her marriage to John Sinfield and we remodelled this in 2016. “On March 8, 2016 she came to my premises with a man she introduced me to as Ian Stewart. “She said she had met someone new, explained they were engaged, and that she was looking for an engagement ring. “We discussed design ideas for just over an hour. Stewart was there as well but Helen was the one interested in discussing specifics. “Ian Stewart was a little bit detached from the process, not particularly engaged, so I very much discussed things with Helen throughout the visit. “We settled on a design and spoke about prices. Helen loved pink diamonds, which are the rarest of the three colour options we were discussing. “The price for the ring was likely to vary from £11,000 to £14,000.
