Are Pistachio and Chocolate SSPs dyed/color treated?

[StevieBoy]

Good day everyone!

I tried searching about these, but I couldn't find much.
Im here in the Philippines, and I've noticed that there are alot of Pistachio and Chocolate SSPs, and even dark "black" ones that are advertised as tahitian..

I have a couple of Jewelmer pendants, and a lot of white freshwater pearls, and a pair of purple freshwater studs, and on my pearls the orient is pretty obvious...
on alot of these SSP vendors... Im thrown off a bit at how large and uniformly colored the pearls are? Are they dyed? They are shiny, but I can't see any orient to the luster?
Is it common to dye SSPs pistachio/chocolate/black?

My understanding is that yes, pistachio and chocolate colored pearls are often color treated.

Here is a GIA article on pistachio pearls from a particular pearl company, whose chocolate colored pearls are also color treated:

I have a range of some natural bronze to brown Tahitians and a few with pistachio greenish colors in some of my mixed strands. They are not so common, though, and not consistent in color. I remember a few years back, dyed chocolate Tahitians were pretty popular. I saw several examples of these pearls and they were very consistent in color. I think seeing several Tahitians with consistent, unusual, colors such as chocolate or pistachio, would give me pause.

Some are, and some are naturally those colours.

In the pictures they all seem so uniform in color, I would wonder too. It depends on the price and the source, of course.

The golden, pistachio and bronze (choco) colored pearls look dyed/treated to me!

Stall owners at Green hills told me that both chocolate and pistachio are dyed. That only white and gold have natural colour.

Most chocolates and pistachio are color-treated. With chocolates, they are either dyed brown or bleached to brown. Natural chocolate and pistachio do exist, but the colors are rare.
