The model is made in the Zbrush program. The model has about 340k polygons. The structure of the ring allows you to change the size, it is better to change it not too significantly so as not to spoil the shape.there are 5 ring sizes available in the set.
Ring sizes US 5,6,7,8,9. if there is no ring of the size you need in the set, you can contact me for help.
Also, the last screenshot shows the size and weight of the ring on the example of a ring of size 5, these data will vary depending on the size that you choose.
