The All Weather Bangles® are each made by hand in Thailand. A single set might contain work produced from three different dates.
The process in which they are made has a lot of variables. For instance, if the humidity is higher in Thailand one day then it ends up affecting the color of the bangle long term.
Therefore, it is normal for some of the beads to have green tint.
The variation in color honestly speaks to the authentic hand-made quality of our products.
