This decoration represents a jewelled miniature version of the Portuguese Military Order of Saint James of the Sword (Ordem Militar de Sant’Iago da Espada).
The obverse is surmounted by a laurel wreath set with green gemstones, topped with a suspension ring of gold. The main body below depicts the Order’s sword-cross, a variant of the cross fleury, whose arms and blade are set with red gemstones, in contrast to the red enamel utilised on the standard insignia. The cross is flanked and supported at the base by two palm branches set with white gemstones, replacing the white scroll that conventionally bears the motto Ciência, Letras e Artes (‘Science, Letters and Arts’).
The knighthood of the Military Order of Saint James traces its origins to the Order of Santiago, established in AD 1170 in the region of Castile, Spain. Its primary foundational mission was to protect pilgrims travelling to Santiago de Compostela in north-western Spain from attacks by infidels and bandits. According to Catholic tradition, the relics of Saint James the Elder (Saint Iago) were discovered in AD 829 in a field guided by a star—campus stellae, meaning ‘field of the star’—which subsequently became one of the three major Catholic pilgrimage sites in Europe. The emblem of the Order comprised a red cross fleury with a lower arm fashioned as a sword blade, symbolising the ideal of defending the faith with sword in hand.
Following the distinguished military exploits of the Order during the Reconquista, Afonso Henriques, the first King of Portugal, introduced the Order to his realm in AD 1172, granting it vast estates and fortresses, such as Almada and Palmela, to serve as military strongholds against Muslim forces in the south. However, to prevent the Portuguese knighthood from remaining subordinate to the authority of the Spanish Grand Master, King Denis I of Portugal initiated the independence of the Portuguese branch around AD 1289. This separation was formally confirmed by a papal bull issued by Pope John XXII in AD 1320, officially establishing the independent Portuguese Military Order of Saint James, headquartered at Palmela.
During the Age of Discoveries in the fifteenth and sixteenth centuries, the Order of Saint James played a pivotal role in overseas expansion. Numerous illustrious navigators and explorers who spearheaded the expansion of the Portuguese Empire—including Vasco da Gama, who opened the sea route to India, and Afonso de Albuquerque, Governor of India—were elite knights of this Order. As the Order accumulated immense wealth, lands, prebends, and privileges, King John III of Portugal obtained a papal bull in AD 1551 that permanently annexed the Grand Masterships of the Order of Saint James, the Order of Christ, and the Order of Aviz to the Portuguese Crown, to be held perpetually by successive Portuguese monarchs.
In AD 1789, Queen Mary I of Portugal instituted a comprehensive institutional reform of the kingdom’s three military orders, secularising the Order of Saint James and transforming it from a religious military fraternity into a secular order of merit. In AD 1862, King Luís I effected a major restructuring of the decoration, designating it specifically as an order of merit to honour exceptional achievements in science, literature, and the arts, while formally establishing its motto Ciência, Letras e Artes. Following the abolition of the monarchy and the establishment of the republic in AD 1910, the Order was briefly suppressed, before being officially restored in AD 1918.

正面上方頂飾為鑲嵌綠色寶石的月桂葉冠，頂端附有懸掛金環；下方主體為聖雅各佩劍十字（Order’s Sword-Cross），為鳶尾花十字（fleury cross）的一種，十字的臂端與劍身鑲嵌紅色寶石，原章則為紅色琺瑯。十字兩側及下方襯有兩片棕櫚枝，棕櫚枝上鑲嵌白色寶石，取代原章書有「Ciência Letras e Artes」（科學、文學與藝術）的白色飄帶。
聖雅各軍事修會騎士團最初源自公元1170年於西班牙卡斯蒂利亞地區成立的「聖地亞哥騎士團」（Order of Santiago）。其最初的核心使命是保護前往西班牙西北部聖地亞哥-德孔波斯特拉（Santiago de Compostela）朝聖的信徒，避免他們受到異教徒與匪徒的襲擊。根據天主教傳說，耶穌的宗徒大雅各（Saint James the Elder / Saint Iago）之遺骨於公元829年在一片由星光指引的田野（campus Stella，意為「星之田」）中被發現，當地隨後成為歐洲三大天主教朝聖聖地之一。騎士團的標誌由一柄下端尖銳如劍的紅色鳶尾花十字組成，象徵著「手握利劍、以信仰衛道」的精神。
隨著騎士團在收復失地運動中的顯赫戰功，葡萄牙開國國王阿方索一世（Afonso Henriques）於1172年引進該騎士團，並封賞大量土地與城堡（如阿爾馬達、帕爾梅拉等），作為防禦南部穆斯林勢力的軍事要塞。然而，為了避免葡萄牙騎士團受制於西班牙大宗師（Grand Master）的控制，葡萄牙國王狄奧尼修斯（King Denis I）於公元1289年左右推動葡萄牙分支獨立。此分離最終於公元1320年獲得教宗若望二十二世（Pope John XXII）的宗座敕令確認，正式成立獨立的「葡萄牙聖雅各軍事騎士團」，總部設於帕爾梅拉（Palmela）。
在十五至十六世紀的大航海時代（Age of Discoveries），聖雅各騎士團扮演了關鍵的擴展角色。許多引領葡萄牙帝國走向海外擴張的偉大航海家與探險家——包括開闢印度航線的瓦斯科·達伽馬（Vasco da Gama）以及印度總督阿方索·德·阿爾布克爾克（Afonso de Albuquerque）——皆為該騎士團的精銳騎士。隨著騎士團累積了富可敵國的土地、俸祿與特權，葡萄牙國王若昂三世（John III）於公元1551年取得教宗頒布的宗座詔書，將聖雅各騎士團、基督騎士團及阿維斯騎士團的大宗師尊號永久併入葡萄牙王室，由歷代葡萄牙君主兼任。
公元1789年，葡萄牙女王瑪利亞一世（Queen Mary I）對國內三大軍事騎士團進行了徹底的體制改革，將聖雅各騎士團世俗化（Secularization），將其從宗教軍事團體轉型為授予功勳人士的榮譽勳章體系。公元1862年，葡萄牙國王路易斯一世（King Luís I）對該勳章進行了重大功能調整，將其指定為專門表彰在科學、文學與藝術領域取得卓越成就者的功績勳章，並確立了其標語「Ciencia, Letras e Artes」（科學、文學與藝術）。公元1910年葡萄牙推翻君主制建立共和制後曾短暫廢除勳章，但於公元1918年正式恢復。
