Most of our jewelry is one size fits all. However, for some styles you have size options to choose from. In case you are confused about your size, do write to us at care@zariin.com or call us at 91-9871103478. If you would like a different size in the same style that you have purchased, you will need to go through the following steps: 1. Contact us to schedule a reverse pickup or alternatively you can send it to us. The pickup charges will be billed to you. 2. Once the unused product is received at our end, we will ship out the new size after charging you the re-shipping charges.Please note that size exchanges will not be possible if the product is purchased during a period of special pricing. We love to pamper our Zariin buyers and have a Rewards Program for everyone. For every purchase made by you, you accumulate 10% of sales value as reward points that are redeemed as cash against your next purchase. For eg: When you buy a Zariin necklace at Rs. 3200, you get 320 reward points, which can be used as a Rs. 320 discount at your next purchase. Happy Shopping!
