Midcentury Planetary Signet Ring


Navaratna is a Sanskrit compound word meaning (among other things) "nine gems". The history and significance of these gems are linked to mythological concepts around cosmology and astrology. According to Lindsay's research, ruby represents the sun, pearl = moon, sapphire = Saturn, citrine/yellow sapphire = Jupiter, hessonite = ascending node, cat's eye = descending node, white topaz = Venus, green tourmaline = Mercury, rose quartz (in theory this should be red coral representing Mars, so this is either a customization or a replacement but rose quartz is associated with both the Sun and Venus). We see similarities here to the coveted "Planetary Rings" made in the Georgian and Victorian eras, where different colored stones represent different planets. Made in 22k gold c. 1950.
