Gold pieces are made from a base of sterling silver, and are then 18K gold plated or coated in a thicker layer of 18K Gold Vermeil. This is followed by a protective anti-tarnish layer. This means it offers more durability and holds better strength.
Diamond pieces are created from Cubic Zirconia for brilliance and crystal clarity. It is a colourless, synthetic gemstone made of the cubic crystalline form of zirconium dioxide. This means it holds strength and is extremely durable.
