November's Birthstone is Topaz and Citrine. Citrine, with it's honey yellow hues is a gem with warmth, perfect for November.Traditionally yellow toned, Topaz is a gem available in a far larger range of colour, including the blues & clear version I use for March and April. However, for November my preferred choice is the stunning petrol teal shades of London Blue Topaz, an unusual coloured gem that shines bright.
