I''ve seen fancy yellow diamonds but I haven''t seen too many other colors. I began to look at an old thread that showed a few, but it would be fun to look at others too if they''re out there. How rare and expensive are they -- for about 1 carat?
Natural diamonds in good shades of red, pink, orange, blue, green, purple etc are all mega $$$$$
Yellow, Cognac, Champagne etc are rather more affordable.
Personally, I think that there are other coloured gemstones that are nicer on the whole.
Green diamonds for example are not as nice as a great emerald or great tsavorite. And okay so the Hope is pretty special, but a lot of blue diamonds are a rather blue/grey colour.
Yellow diamonds are amazing though.
Coloured diamonds are very pretty in small sizes - Etienne Perronet has some lovely pieces.
Are you just asking - or do you have a project in mind?
how i so much agree with you that bang for the buck with color isn''t necessarily with diamonds! for the $$$ a color diamond is going to cost, one could buy a world class color stone.
