Our future will see a move away from the Fashion industry standards with real (un-edited) women in campaigns and aims to confirm it's self as a leader in ethical manufacturing and sustainability.

With foundations firmly rooted on the coast our inspiration is taken from the stunning coastline which surrounds us, often using art and nature in harmony to create truly unique and striking pieces. 

We are proud to offer unique hand-made Silver plated jewellery, that is 100% recyclable.

Producers are carefully chosen for their ethical approach, Eco-friendly production and waste management methods. Every piece from the Trelily collection is handmade by skilled Artisans in a safe and happy working environment.

Pioneering the use of .925 Silver plating onto an Aluminium core we achieve a beautiful, burnished silver which is both hard wearing, durable and the trademark finish that makes our Jewellery so unique.

Our traditional production method has been used in Turkey for hundreds of years.

Made without the use of harmful metals commonly used all over the world like Lead, Nickel or Cadmium, Trelily Jewellery is particularly suitable for customers who may be allergic to these base metals.
