Twig Engagement Ring in 14 Carat Gold and Pear Cut Teal SapphireThis Twig engagement ring in 14 carat gold is cast from a cherry branch and is set with a one of a kind pear cut teal sapphire. Each ring is created from scratch with the design created in wax before it's cast in the metal of your choice. Although starting from the same shape and largely similar, each ring is built to suit the shape and size of the gemstone and is therefore unique. The stone in this image is a pear cut teal sapphire (unheated), 7.
