Maple is a Canadian jewelry company specialized in recycled sterling silver, either as such or plated with 14k gold. A distinctive trait of this brand is their recurring use of type as an ornament through the years. The fonts are either embossed (and oxidized) or debossed in the surface of the jewelry, or can even serve as a full 3D object for the base of some pieces, like the M or Freak rings and bracelet. Note that the Freak ring is not a simple extrudation of Cheee but a properly sculpted inflation of the letter shapes.
Among the fonts they used, we can name a few occurrences of Digestive by Jérémy Landes, Cheee by James Edmondson (both released through OH no Type Co.), Victor Moscoso by Keith Bates, Hendrix by David Nalle, Blackmoor by David Quay, Collegiate FLF by Casady & Greene, and at least two more unidentified ones.
