A woman unwittingly wore an engagement ring hidden inside a necklace by her partner for a year and a half.
Anna only found out her boyfriend Terry had hidden the ring in the piece of jewellery when he broke it open to propose to her at Smoo Cave in the Scottish Highlands.
The large coastal cave complex near Durness in Sutherland had been on a "bucket list" of places the Australian couple wanted to visit.
Anna and Terry have asked for their surnames to be kept out of the public domain because of the media attention their engagement has attracted since telling family and friends.
While Terry proposed to his girlfriend back in November last year, it has only now started to gain worldwide interest from news websites and magazines.
Terry made the necklace from Tasmanian Huon pine and the inside of a sea shell. It was hollow inside and this was where the ring was hidden.
He gave the necklace to Anna as a gift to mark the first anniversary of their relationship.
Terry said: "She wore it every day and everywhere we went, and pretty much never took it off.
"There were some occasions where I was really worried.
"At one point, I thought she was going to trade it with a blacksmith at a market - the blacksmith loved the necklace, and she loved the blacksmith's work - but luckily I didn't need to crash tackle her.
"My biggest moment of panic was when we went through airport security the first time. I hadn't thought about the fact that she might be asked to put it through the x-ray, which could have very quickly turned into an airport security proposal."
When they finally visited Smoo Cave, Terry came up with a story to get Anna to take the necklace off and break the pendant open to reveal the ring.
Terry said: "She stood there dazed for a second, trying to work out what was going on, and then it dawned and she said 'yes' with all the excitement in the world.
"After she calmed down she suddenly stopped moving, stared at me and said: 'Wait... it's been in there the entire time?!! I could have lost it you idiot'.
"She was quite a hilarious mix of happy and angry."

The 34-year-old, who came third in Athens in 2004, has concentrated on the 400m hurdles since November 2010.
She failed to qualify for the World Championships and has since lost her lottery funding, but began training for multi-eventing again four weeks ago.
"I am motivated more and I'm enjoying the fact I could be at the Olympics in the heptathlon," she told Sky Sports.
"It has rejuvenated my feelings for the sport."
Sotherton later said on her Twitter account: "I've had to keep my gob shut for over 2 months about this! So it's a relief it's out! #heptathlon"
Since ending her hepathlon career, Sotherton has been supplanted as British number one by Jessica Ennis and she has previously said that, at her best, she could have run the 2009 world champion from Sheffield close.
Sotherton admits that she does not expect to challenge Ennis on her comeback.
"I don't think I'm going to be rivalling her as I possibly could have been a few years ago. I know where my limits lie, I'm not striving for a gold medal," she added.
The Olympic 'A' qualifying standard is 6,150 points, comfortably below Sotherton's 2005 personal best of 6,547.
She scored 6,517 in her last heptathlon in 2008 before heel and back injuries forced her  withdrawal from the multi-discipline event.

Abbie Bloodworth, 19, died after a blaze broke out at a house in Cwmparc, Treorchy, just before 12:00 BST on 19 August.
In a family tribute, her mother, Samantha Dorricott said: "Abbie was my rock, my world and I miss her deeply."
The cause of the fire is being investigated by the fire service and South Wales Police.
"She was a fabulous and loving mother to her three-year-old daughter Chantelle," added Ms Dorricott.
"She was kind, funny and had a heart-of-gold."
