Here we have a Kingdom of Portugal: A Military Order of St. Aviz Grand Officer Cross.
The Military Order of Aviz (Portuguese: Ordem Militar de Avis, previously to 1910 Royal Military Order of Aviz (Portuguese: Ordem Real Militar de Avis), previously to 1789 Knights (of the Order) of Saint Benedict of Aviz (Portuguese: Ordem de São Bento de Aviz) or Friars of Santa Maria of Évora, is a Portuguese order of chivalry, founded in Portugal in 1146. It gave its name and coat of arms to the Aviz Dynasty that ruled Portugal between 1385 and 1580.

The here offered breast star is executed as a silver eight-pointed faceted star, the obverse centre featuring an enameled green florid cross in silver gilt, surmounted by an enameled red Royal Crown, presenting an enameled Sacred Heart of Christ on the 12 o’clock arm, the reverse with dual pin assembly.
The measurements are 95 mm (Hight – inclusive of Sacred Heart of Christ) x 85 mm (width), with pleasing patina, and well executed enamels. When laying flat down, the whole breast star is 20 mm “thick”.
The condition is extremely fine, with only one hair fracture to the right of the right arm of the centre florid cross. Please mind that almost all of these Military Orders of St. Aviz Grand Officer Stars have heavy enamel loss and/or damage, finding one with only a minor hair crack is seldom in itself. The crack is also only in the underlaying green (translucent) enemal and isn’t “feelable” when touching it and almost invisible to the naked eye. I do feel however i should mention this and tried my best to get it on the detailed pictures of this area. It would for sure be near impossible to find one in better condition!
Simply a lovely grand cross with an amazing design and very large dimensions, for sure a centre(display)piece for any collection of awards and decorations.
