The reigning European 800m champion and daughter of former Scottish sprinter Cameron Sharp had etched a message to herself on her right hand before the race to "get out, strong, commit" and did just that.
Sharp had looked out of contention as she seemed trapped behind rivals in a thriller at Hampden.
But after somehow finding space and to the deafening screams of the sell-out support, she pounded down the finishing stretch to edge out Uganda's Winnie Nanyondo to second place.
It was the second time in 24 hours that a female Scottish runner had delivered silver for the delighted crowd, following on from Eilidh Child's success in the 400m hurdles on Thursday night.
Scotland are now just one short of 50 medals with a distinct possibility the tally will be reached or passed today. Having long since secured their most successful Games medal haul in history, Scotland remain in fourth place in the Glasgow 2014 medals table with 49 overall, of which 17 are gold.
Team Scotland holds 16 more medals than their previous record at the 1986 Edinburgh Games.
For Sharp it was triumph over adversity. She had struggled with an injury which started in May, last year. An operation which was supposed to solve the problem, resulted in a necrotic wound which wiped out her 2013 season.
She continues to use antibiotics for what is a chronic infection and in September, she is due to have another operation to remove the bad tissue. An emotional Sharp, who needed hospital treatment before the race, as her ill health continued, said: "This was honestly my everything. There was no way I was going through everything I have been through not to get a medal today.
"The last year has been an obstacle after an obstacle. Even right up to this morning, I was in the hospital in the village, I hadn't slept at all. I was throwing up all night. I had a drip in my arm."
Earlier a thunder of cheers at the Hydro greeted another gymnastics gold - this time on the men's parallel bars. It was Daniel Purvis who constructed a dazzling final routine to take the gold from England's Nile Wilson.
The 23-year-old, who qualifies for Scotland through his mother Denise, who is from Dundee, clapped his hands and waved to the crowd as he landed his routine.
There was elation at Kelvingrove as the Scots produced a third lawn bowls gold medal as Arbroath police officer Darren Burnett crushed his men's singles final opponent Ryan Bester of Canada 21-9. The 38-year-old veteran of three Commonwealth Games is one of the few policemen to be given dispensation to take time off after being named in Team Scotland's 10-strong bowling line up.
Earlier at Kelvingrove Scotland beat the Auld Enemy to gold in the fours final. After celebrating their 16-8 win against England in the final with a bouncing huddle, the fab four of Paul Foster, David Peacock, Neil Spiers and Alex 'Tattie' Marshall announced that they would be celebrating in "every pub in Glasgow".
Scots flyweight Reece McFadden had to settle for a bronze after losing his semi-final bout on a split decision to experience Australian Andrew Moloney.
Meanwhile new Scots boxing hero Josh Taylor said he was "100 per cent confident" of landing another gold for Scotland today after beating Englishman Samuel Maxwell in the 64kg semi-final.
The 23-year-old fighter said: "There is expectation, I have had that since the start of the year, before I was even selected to go to the Games, that I am going to go and get the gold. The first fight here got to me a bit, but I have the experience now to deal with it."
Later 20-year-old Motherwell boxer Charlie Flynn ensured Team Scotland would get another silver, as he beat Joseph Cordina of Wales in the 60kg semi final. Meanwhile, Scottish boxer Stephen Lavelle secured bronze after losing his 91kg semi-final.
