Antique Dyed mother of pearl brooch and dress studs - English seashell fashion

A boxed set of dress studs, similar to those sold on BoutiquebyRachelco however these are of Mother of Pearl and the Mother of Pearl is dyed a rich vivid blue.
 
These studs, unlike most of these, feature a brooch that has a blue stud too. 
 
These studs are very good, not damage and the box, though a tad tatty is good too and closes well so these are ready to wear.
 
I have sold and my mother, BoutiquebyRachelco has sold to film/theatre companies, a similar set  of dress studs like these. These dress studs and brooch are ideal for adding authenticity to a project for a film or theatre production as these are period Art Deco/Nouveau.
