What it is, is a Humbug. The "Spectrostatic Nocturnium Bracelet" is an overpriced piece of s**t, decorated with a bunch of high falutin adjectives in an effort to get it sold to the gullible.

Some pages just say 'Inspired by Victorian Design': http://www.outwestmktg.com/store/detail.cfm/alchemy-bracelet-steampunk-spectrostatic-nocturnium-cuff/pid-5854 - This is the most detailed description I could find: 'This Alchemy bracelet is an early scientific instrumental band for controlling moonlight wavelength emulations; in antiqued pewter and solid brass. Size: Medium Adj. Bracelets are all hand cast in fine English pewter. Bracelets are mostly one size, adjustable, covering from small to large. Where fixed sizes are indicated, these are divided into approximate categories. Small 153-191mm, med. 178-229mm, large 191-242mm. When supplemented with Adj. a bangle has some degree of adjustment, by gently squeezing open or closed to fit. Alchemy Steampunk collection revolves around Ezekiel Empire Rosensteins a.k.a. EER, Victorian descendant to the original, C18th Dr. von Rosenstein, incredible Galvanic Matter Transposition System, for pronto mass remotion, the earliest known teleporter, a kind of three dimensional fax machine. Known as the GMT, this sensational invention was, sadly, completely lost to science. However, from a combination of surviving fragments in our archives, anecdotal evidence and recently found early drawings, Alchemy Gothic 1977 have been able to reconstruct several of Rosensteins GMT principle elements.'

Now, his successor, Ezekiel Empire Rosenstein (1790-1889) is Victorian radical scientist and leading light of the London Archimedian Society whose accomplishments include the outrageous pronto mass remotion technique (Teleportation) and its stunning Galvanic Matter Transpositor which has since, sadly been lost to science.'

From what I gather, Ezekiel Empire Rosenstein was an engineer who invented the Galvanic Matter Transpositor. The work of this forgotten genius has recently been "rediscovered". OK. Good fiction. Good fun!' Source: http://blog.dugnorth.com/2012/06/steampunk-ring-with-realistic-human-eye.html
