Flora Collection showcases rose gold jewelry, the most popular collection of Mia Siya. Earrings, bracelets and rings are showcased under this collection. Rose gold, also known as pink gold or red gold, is a mixture of pure yellow gold with a high percentage of copper. It has a very subtle and delicate colour that may intensify somewhat with age due to a slight, but attractive, tarnishing of the copper. Rose gold is created by increasing the copper-coloured alloys mixed with the gold and decreasing the silver-coloured alloys.14K rose gold contains as much pure gold as 14K yellow gold but, because of the increased copper, is slightly pinker in colour.
