Tungsten ring with a cross design. Approximately 7mm wide and 2-2.1mm thick (estimated). Unisex, unlikely to cause metal allergies. Color: Tungsten Silver Size: 17 ◎ The color is silver, but it's "slightly darker" compared to platinum or stainless steel silver. This hue is "unique to tungsten." Those who haven't seen the actual product may not be able to tell until it arrives, so please consider this when purchasing. ◎ Tungsten is very scratch-resistant (unless rubbed with a diamond, etc.), so you can use it without worrying about scratches. ◎ The size is 17, but it widens slightly from the center of the hole towards both ends. Therefore, the size 17 seems to refer to the center portion. ※ Photo 11 is quoted from the product page of the purchase source. Because the width is wide, it is measured with a ring gauge as shown in the photo. Ring gauges are usually used to measure rings about 3mm wide. ◎ Photos 1 to 5 are of the actual product.
