Lost: Rings of sentimental value

Today my Dad has been a target of a distraction robbery.  Whilst waiting for the Yorkshire Mill to open in San Javier he was approached by a Spanish woman called ‘Maria’ who was very friendly, ‘ran a cleaning business’ and left her name and number (medium/long dark hair, 40 -50, petite and carrying a bit of weight).  It wasn’t until my dad returned hone that he realised that during the introductions and hello hug/embrace his two necklaces had gone missing.  One held a locket with photos of my Mum and the other had her signet ring, her engagement and wedding ring.  The signet is 9ct gold square faced with JFG on the front with MAB on the inside.  The engagement ring is 9ct band with a flower, diamond in the middle with 6-10 sapphires on the outside, the wedding ring is a D shaped 22 ct ring.  Please don’t let these go for scrap!! If anyone sees these for sale please contact me, a reward is available.  The Guardia are informed.
