「King crimson」「king with bloody reddish-brown pasty goo」used today as a reference to any sort of GEMSTONE but specifically to PEARLS, or generally to RARE PRECIOUS STONES (literally, 'rare' means 'red') as in the stones of the king after deflowering one of his FEMALE ENTERTAINERS. The English word 'pearl' is derived from the Latin meaning 'leg' perhaps because of where DROPLETS are often found when stuck to humans. PEARLS of any color, and pearl nacre smeared on inner walls, is used in Chinese euphemistically to represent ejaculated semen, that「small amount, 3/5 of an ounce (勺)」as droplets or smeared inside shells as mother-of-pearl, the source of motherhood inside the walls of a cavity with two sets of lips such as clams and oysters (see 貝, the goal of emissions, as that outer shell, and as the lord's fleshpots, his wealth).
　「King」with「wood on person prostrate」or「king's woody overlaid」describes those pearly BEADS, droplets of semen becoming necklaces, ear and hair adornments, clearly described in many other glyphs while engaged in mammary intercourse, coitus between a squeezed teat [tit] set.
　As RED PEARLS: various emperors, kings, lords over the millennia were fond of dutifully deflowering thousands of virgins as their lot in life, rather than performing other labor, hence the「lord, king with a bloody woody」depositing pearl-like BEADS, DROPLETS becoming crimson-colored inside tightly-closed flesh seams having two sets of lips as juicy as a fresh-water clam was a fitting analogy of that daily grind describing his FEMALE ENTERTAINERS. Note that most bivalve molluscs can produce pearls, and not only oysters. Oyster blood is colorless, not unlike the bulbourethral fluids discharged with pearly beads of semen from a「kingly life source, sap, head with an immature ewe lamb」that may or may not subsequently mix with her blood after the hymenal rupture and the pearly discharges from her Bartholin's glands…how the droplets become reddish-brown is left to your imagination.
　「Throughout much of recorded history, a natural pearl necklace comprised of matched spheres was a treasure of almost incomparable value, in fact the most expensive jewelry in the world. …Before the creation of cultured pearls in the early 1900s, natural pearls were so rare and expensive that they were reserved almost exclusively for the noble and very rich. A jewelry item that today's working women might take for granted, a 16-inch strand of perhaps 50 pearls, often costs between $500 and $5,000. At the height of the Roman Empire, when pearl fever reached its peak, the historian Suetonius wrote that the Roman general Vitellius financed an entire military campaign by selling just one of his mother's pearl earrings.」
