HBO Global Licensing has partnered with Pyrrha to launch the Game of Thrones jewellery collection.
The new range features unisex talisman necklaces and rings handcrafted from sterling silver and bronze.
Each talisman features the sigils of the different houses of Westeros - Targaryen, Stark, Baratheon, Tyrell, Lannister and Greyjoy.
"We were thrilled when HBO approached us to create an official Game of Thrones jewellery line," said Pyrrha designer Wade Papin.
"While designing the pieces, we felt it was important to embrace the spirit of this groundbreaking series while still retaining the signature Pyrrha style."
Jeff Peters, director of business development in HBO's Global Licensing & Retail department, added: "The historically inspired aesthetic of Pyrrha's work made them a perfect match for a Game of Thrones jewellery line.
"Fans of the show will be very excited to represent their favorite noble houses with these expertly crafted pieces."
The range is available at the HBO Shop (store.hbo.com), Pyrrha online and select Pyrrha retailers. Prices range from $98 to $900.
