Ireland, the current Triple Crown holders, are the only team that can deny Warren Gatland's side that honour now. Despite the history of the Triple Crown in home nations' rugby, there had never been a permanent trophy produced until 2006.
The trophy, commissioned by Six Nations' sponsors RBS, is a silver dish measuring 42cm wide and 5cm deep and weighing a hefty three kilos. It was produced by Hamilton and Inches of Edinburgh and took over four months to make.
In its inaugural year, team captain Brian O'Driscoll lifted the trophy for Ireland at Twickenham on March 18, 2006 after a last-minute try from Shane Horgan gave Ireland a 28-24 win over England.
Ireland were also crowned Triple Crown winners - without the trophy - after beating Scotland 37-16 at Lansdowne Road in March 2004.
O'Driscoll and company did likewise at Murrayfield twelve months ago but this time they had silverware, once again, to celebrate with.
The recent list of Triple Crown winners, since Ireland's last championship success in 1985, can be seen below:
1986: Not achieved
1987: Not achieved
1989: Not achieved
1993: Not achieved
1994: Not achieved
1999: Not achieved
2000: Not achieved
2001: Not achieved
2006: Ireland (trophy awarded)

JONES READY FOR BATTLE OF THE NUMBER 10S: With the outcome of Saturday's game at Croke Park likely to be close, the performances of number 10s Ronan O'Gara and Stephen Jones will be so vital to their respective team's cause.
The pair know each other well from opposing each other at club and international level and they were also colleagues in the 2005 British & Irish Lions squad.
Jones, who has gotten the nod to start for Wales over James Hook, knows just how important O'Gara is to this Irish team.
The 30-year-old said: "Ronan brings a lot of stability (to Ireland), he's every effective and efficient in his decision-making. He keeps the ball in front of his forwards and I'm sure they thank him for that.
His kicking game is very good and gets the back-line moving well. He's a very, very good player and a player I respect."
As well as keeping tabs on O'Gara's form, Jones has had a difficult task of his own in beating off Hook for the Welsh number 10 shirt.
But the Llanelli Scarlets clubman welcomes the current pressure on him to gain a starting slot, admitting: "There's fantastic competition for places in the squad at the minute - from my point of view, it's the best I can remember it. It's only good for Welsh rugby."

HOME COMFORT FOR IRELAND: The list of matches below makes for pleasant reading for Ireland's players and fans alike. The men in green have not lost at home to Wales since April Fool's Day in 2000.
The current Ireland side have also won three of their four games to date at their temporary home of Croke Park - with a late try from France's Vincent Clerc handing them their only defeat so far.
Ireland coach Eddie O'Sullivan feels that his side's home advantage this weekend against Grand Slam-chasing Wales could have a telling influence on the game.
"We're comfortable at Croke Park after four games there. We're starting to settle and getting a good feel for the place," he said.
"Wales haven't been there before, and it's a very impressive stadium. They're very aware of that and know it will give us a lift, like the Millennium Stadium raises their game.
"Overcoming that will be quite a challenge for them. It's a stepping stone because they havenâ00t been there before. If we can create a big atmosphere it will certainly count in our favour."

"The fact I don't have many caps doesn't faze me. All I know is that I have two more than Rob Kearney (my Leinster team-mate) - as I was telling him earlier in the week!
"As long as I go out there, do my job and get the respect of those guys who have the experience. If they respect you they'll play for you and that's what I want.
"I have no problem telling someone if they're wrong and I take any criticism on the chin. I have no problem speaking up."
- Ireland number 8 Jamie Heaslip on how he deals with his inexperience at international level and working with his more experienced colleagues in the Ireland pack
"It's nice to go back. I had some great experiences with Ireland and my time there, living in Galway and the west. I've a lot of friends there.
"I'm looking forward to catching up with some friends and some of the players in the team that I was involved with. It's exciting going back."
- Former Ireland coach Warren Gatland talks about his return to Ireland this weekend as he hopes to guide Wales to a Triple Crown
"Handling (Brian) O'Driscoll will be a big challenge that I havenâ00t had to deal with before. He's powerful and fast but the one thing you can't coach is speed of thought.
"O'Driscoll has a great rugby mind and is incredibly quick to anticipate what will happen. That's the hallmark of a great player."
- Wales assistant coach Shaun Edwards gives his thoughts on coping with the threat of Ireland captain Brian O'Driscoll at Croke Park
60 - Saturday's game will mark Shane Horgan's 60th cap for Ireland. The Boyne clubman, who has been promoted to the right wing owing to the injuries to Geordan Murphy and Girvan Dempsey, will be a watched man - he has scored three tries in his four appearances to date against Wales
7 - The number of players in the Ireland matchday squad for Saturday that have never played before against Wales at senior level. In the starting line-up, Rob Kearney, Tommy Bowe, Eoin Reddan and Jamie Heaslip are first-timers, while replacements Bernard Jackman, Tony Buckley and Paddy Wallace have also never faced the Welsh
3 - The number of New Zealanders who have coached Wales in recent seasons. Warren Gatland, a former hooker and captain of Waikato, is following in the footsteps of his fellow Kiwis Graham Henry and Steve Hansen. He is the 19th Wales coach since David Nash in 1967
