E739 Blue Star Sapphire Cabochon Ring set in 15 karat Yellow Gold:


The ring dates to 1840 to 1850, which means that the raw Sapphire stone was hand polished, a process that took months to do. The size of the oval Sapphire is 1 1/5 carats and is bezel set. The Sapphire shows a “Star” with a beam of light is cast on the stone. The setting is of 15 karat yellow gold (tested), all around the band is a design with black enameling. This would be a hard enamel made of black glass and baked into the gold. On each side of the gemstone is a gold bead set on the ring's shoulder. The size of the ring is more significant and was probably a fore-finger ring, a tradition that Victorian's took from the Renaissance period of wearing a fore finger-ring.
Star sapphire is a rare variety of Sapphire that exhibits a rare asterism under specific lighting. When viewing star sapphire, a six-rayed star will appear to float across the surface of the stone. The effect is best viewed under a direct light source and while tilting and rotating the stone from different angles. Star sapphires contain unusual tiny needle-like inclusions of rutile. (Rutile is a black or reddish-brown mineral consisting go titanium dioxide, typically occurring as needle-like crystals).
Sapphires are considered a precious gemstone today and are very hard on the Moh’ scale with a rating of 9, which is the hardest stone in the world next to diamond, which is a 10 on the Moh’ scale.
Information on Sapphire Gemstones:

The expert recognizes Ceylon sapphires from the luminosity and brilliance of their light to medium blue color.
Sapphires in the Victorian Language of Gems means “Innocence.”
The term Cabochon:
A cabochon (Cabochon) is a gemstone that has been rubbed and polished into a simple rounded shape, as opposed to a facetted cut. Up until the 1400s, gem cutters were constrained to cabochon style cuts and odd asymmetrically faceted cuts due to the limited technology at hand. The resulting shape has a convex top with a flat or concave back. The term cabochon is used to describe any gemstone cut a shape that is not facetted. In this time, Monk's would polish cabochons. They would use soft dear skin with pumice and oil.
This is a quality ring, and gemstone is all in excellent condition and strong to wear. The band's size is 9 but can be resized if needed without taking away the value of the antique ring.
