Hi Sweetfrock,
I don't know which works best. I do know that peacock and caramel/brown overtones both work well for me, and I have fair Asian skin. So far I only have pendants though.
When I visited Singapore last year there seem to be a lot of stores selling Tahitian pearls so you probably can find pearls with different overtones to try on. Do you mind letting me know where is a good place to buy pearls in Singapore? I probably would be there again. BTW the food in Singapore was very good!
Regards,
Pernula
