You must email me for a formal quote on custom jewelry, but I hope you'll read this page first to get some idea of what goes into pricing them. For a rough guess at how much your bracelet might be, though, you can multiply the number of crossings from the chart below by the same factor as used for rings. See the "gold rings" page for those, and a deeper discussion of crossings.
The chart below shows the number of crossings in several Turk'shead knots that can be used as bracelets. Its main utility is in demonstrating why (and by how much) a more complex knot is relatively more expensive than a simple one.
Bracelet prices, like those of my rings, are dependent upon the complexity of the knot and the cost of materials. The "crossings" are the places where the paths cross in the knot, and I use the number as a fairly accurate assessment of the amount of work that I actually invest in any given item. Your cost for a bracelet would be calculated by using the number below, multiplied by a factor based on labor and cost of materials.
The choices shown here are either items that I have actually made, at least in prototype, or items that I anticipate being able to produce without significant delay, as I have already made the tools required. Click on the links to see some of the ones that already exist.
The reason I chose twentynine and thirtyseven bight knots is, purely and simply, the fact that they are prime numbers. This is not only esthetically pleasing to me, but also circumvents the difficulty of choosing a number of leads that will work as a "single line" knot, i.e., one strand running through the entire knot. Even though the examples below all have odd numbers of leads, I could just as easily produce, say, a sixlead by twentyninebight bracelet, if I were so inclined.

The size of a bracelet can change, from its "full stretch" size with the band at its narrowest, down to the actual size of the wrist, when it is compressed to a close fit, with the band being much wider at that point.
Please be aware that I will not make Turk'shead bracelets with clasps. If I call it a Turk'shead, it is, by definition, continuous.
I do, however, make another kind of knot into a bracelet, it's called a Prolong knot, or Oceanplat, or the Chinese knot. See this page for a brief introduction to the knot. I will make one for you in any appropriate metal, or teach you to make your own. The Prolong knots I teach most often, and make many of, have 96 crossings.
There are some other flat mats that extend in such a way as to make bracelets and chokers, please feel free to email me for more information
