Tortoise Shell Pique SET; earrings and pendant

Also used as mourning jewelry: Pique.
This nice set is inlayed with very tiny gold and silver flowers. Very comfortable to wear because it is so light in weight. As always I admire pique just as Micromosaic because the lot of working hours it take to make it.
And in this case also the skilled handcraftman to make all the tiny little flowers as decoration. Is there any one of the collectors who knows if there are some different directions and/or different time periods in Pique jewels and if yes please tell us !
