Due to the large amount of ring sizes that exist, and due to the workload that comes with making different ring sizes available to purchase; such as resizing the product multiple times for every ring size and every ring product, calculating all the prices for all these different ring sizes, alongside calculating the changes in price with material as well, all NiTrideDesign rings are therefore only available to purchase on the product pages in US ring sizes 10, 11, and 12. Although this is true, NiTrideDesign rings are still sold and are available in ALL ring sizes.
You can purchase a ring in any ring size by clicking the Customise Order button, and requesting the ring in a different ring size for Free. This will allow me to resize the product and calculate the price for you on demand, meaning I only complete the work of making a ring available in a size if it is required.
If you are not sure about what ring size you need, you can check the ring size chart below.
