Halley’s comet, a short-period comet, can be seen in the sky's above the earth every 74 to 79 years. Sightings of the comet have been recorded in history since 240 BCE, but it was British astronomer Edmund Halley who gave the comet its name in 1705. Halley realized it was the same celestial entity whose passage had been noted by the ancient Greeks, Babylonians, and medieval English, and he correctly predicted its return in the year 1835. This massive silver and rose cut diamond brooch is a fanciful rendition of the famous comet made to commemorate its apparition in 1835.
