After three days of wet, miserable conditions Ramsay shone as the Swiss clouds parted to win a second Tour title with a final-round 66 for a 16-under-par tally.
"It's nice to receive a big cheque and be handed a nice big trophy, but to be able to say you are a multiple Tour winner, given how strong the European Tour is, is incredible," said Ramsay, whose maiden win came in the 2010 South African Open. "It also vindicates the faith that people have shown in me."
Ramsay went into the last round leading Lawrie by one stroke but eased away to be four ahead after four, then five shots clear at the turn.
If there was a defining moment in Ramsay's push, it was a gap-wedge shot from 115 yards out at the par-five 14th, which he put to 10 feet before holing his birdie putt to leave him four shots ahead with four holes to play.
There was a small fist pump when his winning putt fell, some 74 events since his win in South Africa, as Ramsay joined Colin Montgomerie as the only Scots to have claimed this Alpine event.
"Between winning the South African and now I have made a lot of big decisions, such as where I want to be based and what I want to do, and the people that support me," said Ramsay, who is getting married in Minnesota on September 21. "I treated today as though I was playing with my mates at the Golf Club of Georgia, people like Rick Bortles and Jeff Pattern, who is the pro at the course.
"I knew if I could do that and stick with my game plan I would be happy and be sitting here now. But then I've achieved more and I've played unbelievable well. I played really well against two of the best players out here in Paul (Lawrie), who is playing the best golf of his career, and Danny Willett, one of the best up-and-coming players we have in Europe. "
The win moves Ramsay from 45th to 20th in the Race to Dubai ratings and, when the world rankings are adjusted, into a likely 70th position.
The Scot joins an illustrious list of European Masters winners including major champions Bobby Locke (1954), Kel Nagle (1961), Severiano Ballesteros (1977, 1978 & 1989), Ian Woosnam (1982), Nick Faldo (1983), Jose Maria Olazabal (1986) and Ernie Els (2003) with his name on the trophy. Ramsay's name will be added to a plaque and placed on the Walk of Champions along the main street of the Swiss ski resort.
Lawrie carded 70 to share sixth place on 11-under par and, despite missing out on a third win this year, he was full of praise for the victor.
"Richie played magnificently and to start the day one ahead but make the turn in five under was tough to beat," he said. "He deserved to win."
"Despite the eagle at the first, I holed nothing all day and just struggled with the putter all week," the Ryder Cup player added.
Lawrie next plays tomorrow and Wednesday's pro-am event at Skibo Castle, then his own event on Deeside the week before heading to Medinah.
Four players – England's Danny Willett (69), Australia's Marcus Fraser (66), Frenchman Romain Wattel (66) and Sweden's Fredrik Andersson-Hed (66) – tied in second place at 12-under par.
Bathgate's Stephen Gallacher (68) and Borderer David Drysdale (70) shared 34th place at four-under par
Marc Warren, who posted a 72 for a one-under-par tally, headed straight for Hilversum for this week's KLM Open, while Colin Montgomerie, after a closing 74 for a two-over-par total, will be in Geneva for two days hosting a corporate outing before also making his way to this week's Dutch event.
