I bought this strand of pineapple quartz points at a local bead shop several years ago, and was entranced! In lower light, you notice largely the glassy pale yellow (very nice), but when the sun hits it--Shazaam! It glows with aqua swirls like Galadriel's phial, that she gave to Frodo to light his way (just color me geek). I combined them with copper antiqued to a rich chestnut, and dotted the earwires with aqua chalcedony, which matched the swirls in the quartz nicely (and color me matchy matchy).
Of course, what else could you wear with them but this? I think I have something like this lying around.
I have more of these points, I think next I will do a pair in sterling!
