Large sizes are rare, and fine examples truly mark the borderline between pink sapphire and ruby.
Often they are priced as rubies. There are also African varieties which run the gamut of color but large sizes are rare in Tunduru but many new pinks are coming from Madagascar, these are relatively new material and the full range is still to be explored. Sri Lanka produces many pretty shades of pink, tending towards the lighter side and some with tinges of violet and purple. Other popular sources are Vietnam, the hot pink stones from Madagascar and the Tunduru region of Tanzania.
