チャンピオンリング
L.G. Balfour of Attleboro, Massachusetts and Jostens of Minneapolis, Minnesota are the two companies that have produced the majority of championship rings for the four major professional sports leagues. Tiffany &amp; Co. and Intergold (now a Jostens subsidiary) compete with Balfour, Baron, and Jostens in the design and manufacturing of championship rings. Tiffany has been gaining momentum with NFL teams, having made the Buccaneers XXXVII, Giants XLII, Saints XLIV, Giants XLVI, and the Seahawks XLVIII rings. Recently, newcomer Baron Championship Rings has gained momentum in the professional championship ring market, having designed and manufactured the 2016 NBA Champions Cleveland Cavaliers rings (at the time the heaviest NBA Championship ring ever made, weighing in at 165grams and 105pennyweights) and the 2019 NBA Champions Toronto Raptors rings (presently the largest-ever championship ring).
