Handmade Sterling Silver Jewelry

Tonkin Jewelry's products are made of sterling silver 925 and handcrafted from the stage of smelting to polishing. For that reason, each product is unique despite of the same design, which differs from mass production. Our design features a look of youth, elegance and simplicity that stands out from the crowd. We pay attention to every detail of each product, with a mission of blowing “a soul” to every piece of silver jewelry.

At Tonkin Jewelry, customer experience is of the most important to us. We continuously strive to ensure the best shopping experience by good and professional service. We also take quality seriously so that our customers can see and feel it in every single item that we sell. We hope that you will wear our products with the same love and treasure as when we make them.

Size Guide

When shopping for ring or bracelet, it is important that you should be certain about your size. Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle. Same goes for the bracelet.

There is one simple way to double check your size if you are not sure:

Use a fabric measuring tape and measure your finger/wrist. Lie the tape against the skin (do not pull it tight) and record your measurement. If you don't have a measuring tape available, use a flat ribbon and check your measurement against a ruler. After that, divide the number into 3.14 to get the diameter. For normal rings, such figure should be between 1.3cm (33/64 in) and 2cm (25/32 in), average girls’ size is 1.6cm (5/8 in). For normal bracelets, the diameter should be about 5.2cm (2 in 3/64") to 5.8cm (2 in 9/32"). 

Please keep in mind that it is preferable for the jewelry to be slightly loose rather than tight. Consider if you like your ring/bracelet fit to be more on the snug or loose side. If yours is between sizes, we recommend that you round up to the next available figure.
