Namibia gets my vote for blue in tourmaline. It may not have the neon look of Paraiba, but I keep finding room in my collection for it. This dot of color is bright blue and stays blue even in my yellowish light. It appears to be eye clean, but I did have problems with stability in members of the lot that this rough came in, so I think I rather look at this beauty than set it. It weighs .27 carats.
