If you're looking for good basic earrings, studs, rings, necklaces or even bangles, Krishna Sons Jewellers is a great place to head to. Although a small shop, they have a decent variety of jewellery and offer dressier assortments too. While you won't find a crazy variety in designs, you'll definitely find stunning pieces like emerald rings and necklaces that you can wear on certain special occasions.
They also stock heavier gold jewellery sets that perhaps you can pair with that silk sari of yours.
