The gold silver and bronze medals weigh 100g each and feature the Glasgow 2014 Commonwealth Games identity, which was designed by Marque Creative.
More than 1,380 medals will be awarded throughout the Games, which start in July, and each is being hand-made in Glasgow.
Boyd says, ‘I hope I have designed something that stands proud as an interesting and unique object but, more importantly, something that celebrates each athlete’s individual achievement.’
Boyd worked on the designs with a team from GSA’s Silversmithing and Jewellery Department: Helen Marriott, Andrew Lamb, Anna Gordon, Nigel Munro, Yusuke Yamamoto, Satoko Takemura, Rhona McCallum, Malin Winberg, Shona Guthrie and Michael Pell.
Glasgow 2014 also unveiled designs for the medals ceremonies – including podiums, gifts and clothes for the medal-bearers.
Furniture designer Paul Hodgkiss created the wooden podiums, trays and gifts for each athlete.
Fashion designer Kerry Nixon designed the dresses being worn by female medal-bearers and styled the male medal-bearers. Nixon worked with Harris Tweed, which provided a specially made fabric for the clothing.
