hi all,
i want opinion about buying semi precious stone beads like argate,jade,garnet,
opal,coral.......etc in uk...
anybody knows the place where we can buy it?{in uk,sheffield ,birmingham,manchester}
if we buy in online shops will it be of original and guaranteed quality?
pls....... tell me ur opinion if you have bought?

hi even i searched for beads in uk but i could find online on sarvoski website i think it is trusted and famous but you cant find the beads in stores and other optionmis if you go via duabai to india then if you r staying like transit then in city centre you can find a big sarvoski store they sell different coloured beads they r lovely but costs you cheaper online and mostly people buy beads from USA it seems they have exhibitions so try in debenhams,selfredges,may be jewellery quater birmingham i hope this information helps
