We do not use any type of chemical in our plating process to enhance the shine & luster of the metal which are harmful to your skin. How to mention the ring size? As all our rings are’made to order’, you can get any size you want. We offer full customization on each product. If you have a designing mind, we can manufacture customized products as well. We offer engraving service absolutely at free of cost on each product. All our products are’Made to order’ so it takes about 20 days in processing the order as we do not carry any physical inventory.
