Yes, generally FW pearls cost less than akoyas.
Akoyas are typically bleached to remove undesirable off-colors, then soaked in a large bottle of pink dye to add a pink
overtone, because generally speaking it is flattering to most women and the market desires it.
But against skin they look white.
Freshwater pearls that are pink or peach may be a lighter or darker pink/peach. But that is their
body color, not just an overtone color, and against skin they look pink/peach.
Do this:
Take a photo of them on your wrist or neck.
Take a photo of them against a white paper towel.
What color are they? What do you see?
This photo shows 3 white strands-- the left are white SSP, the middle are baroque akoyas that have been pinked, and the right are metallic white FWP. The akoyas were pinked but they look white on my skin.
These are the same 3 in a white box lid. This time the akoyas are at the top. On a white background the pink is visible, but it is pale.
In this photo, same akoya strand, the pink isn't so visible.
This is a FW strand with lots of pink/peach pearls.
And here they are on my neck
You are the one with the pearls in front of you and you can look at them on different backgrounds and different light. I think you will probably be able to figure out what you have.
