In karaikudi, there are few north Indian people whom you call as ''settu''. There are jewelery sellers of diamonds mainly. Don't ever think that they are less quality. They are thebest as far as in tamilnadu. The reasons are:
1. They show a collection of diamond stones, ranging various prices and u can even choose the stones that you want on your jewel
2. If you are experienced, then you can choose the best
3. They show you many catalogues, and you can choose the design , can even mismatch the chain pattern from 1 model and pendant from another and so on.
4. You can choose between open setting and closed setting in the jewel.
and what not, everything is available custom-made and can be delivered within a month or so. They also have ready-made jewel pieces like other shops.
I really wanted to reply this post seeing your post wordings ''Karaikudi offers diamonds forcheap prices, dont know about their quality"
Hope I have explained something to you which is 100% true
ofcourse, the models in tanishq are very nice as far as I know. Have not visited the other shops because we always have our own jewellery designed and done marvellously. Will post pics if you like to see my wedding collection,
