9ct Ina alloy
I make most of my jewellery in a 9ct alloy of my own concoction which is about one third rose gold, two thirds yellow gold.  It’s a lovely warm colour, more lively than 9ct yellow but not as bright as 9ct rose gold. 
That’s my normal choice of gold colour but I am more than happy to make the same pieces in 9 yellow, 9 rose, 9 white, 18 yellow, 18 rose, 18 white gold or platinum. Please enquire.
