New to the forum, so apologies if this isn't the right place to ask. I have a collection of natural colored diamonds (pink, yellow, green, blue, & gray), all of great clarity but nothing too large. I was wondering what are others' thoughts to colored diamonds' prices in 10 years? 20 years? Or longer. Are certain colors looking better in the long run than others? I only like natural, but obviously, the direction of consumer interest is going lab. I also wonder if interest goes to lab, will natural altogether no longer be available/easily accessible in the U.S. because of the "ethical" concerns surrounding them (e.g., social media criticizing people having them already). I'm not an expert in the field, just liked to collect them. None of mine are even set, though I have layouts planned for them.
