The measurement of sales of popular music starts high relative to the wedding anniversary scale, concentrating on gold and platinum (see gold album). This is commonly used by restaurants to indicate how elaborate (and expensive) set meals are. In Japan, the traditional Sho Chiku Bai (松竹梅) ranking system has a hierarchy of pine 松 ( matsu), bamboo 竹 ( take), and plum 梅 ( ume).
In some variants there is a Bronze Age, an interim between the Iron Age and Silver Age. In general usage no precious stone is considered to outrank the diamond.Īncient Greek mythic-cultural cosmology depicted a decline from a golden age to a silver age followed by an Iron Age. In 2017 the 65th anniversary of the accession of Elizabeth II was widely referred to as her "sapphire jubilee" or more specifically as her blue sapphire jubilee (see Sapphire Jubilee of Queen Elizabeth II) but more traditionally the sapphire anniversary is considered to be the 45th. Wedding anniversaries extend the jubilee hierarchy with various sequences of substances filling in many of the gaps between the same major milestones. The sequences can provide interesting examples of the arbitrariness of semiotic signs. Precious metals appear prominently in such hierarchies, but as they grow, gems and semi-precious materials may be introduced as part of the system. In popular culture, sets of precious substances may form hierarchies which express conventional perceived relative value or merit.
