Enter Metro Plaza, take a left and you'll find Fantasy (shop number 1004A) towards the end on your left-hand side. It's a small shop but has really pretty designs in Korean metal, steel, oxidised and stone.
If you're looking for beautiful long earrings, specifically, in metal and steel, then this is the shop for you. We also loved their collection of rings. From a basic one to huge round or square-shaped oxidised ones, they have it all and in pretty amazing designs. A basic ring would cost you INR 60 while you've to shell out more for the nicer ones.
The bracelet collection is not that impressive but the necklaces are quite good, perfect for casual or party wear. The neck pieces start at INR 100 and can go up to INR 700 depending on the design you choose. The earrings start at INR 150. There are some that costs as cheap as INR 30 but aren't that pretty. We suggest you go for the long ones.
