"The crowns of two 20th century British Queens consort, the Crown of Queen Alexandra (1902) and the Crown of Queen Mary (1911), reflecting their origins as European princesses from Denmark and Germany respectively, each had eight half-arches. In addition, the British Imperial Crown of India was designed with eight half-arches to indicate the British monarch's claim to imperial title in India.
"The Crown of Louis XV of France (1722), reflecting the European norm, has eight half-arches."
I have never seen any other explanation of the eight arches in these three British crowns. I wonder whether this is accurate.
