Although we were aware that lavender-dyed jadeite is on the market, because we have purchased some for our collection, we have rarely been asked to identify it. Recently, we examined a bead necklace that proved to be pink-fluorescing, lavender-dyed jadeite showing a distinctive spectrum (Figure 7). The dyed stones in our collection do not show either reaction.
