Natural star sapphire
Star
sapphire gems are one of the most unique gems that come with stars on top of
it.
Formation
A
Star Sapphire is so named due to the appearance of a star-shaped format which
presents itself when a single top-down light source lights the sapphire. This
format results from a phenomenon well-known as asterism, found in several types
of gemstones. They are due to intersecting needle-like impurities in the star
sapphire gems. The inclusion is often the mineral rutile, composed primarily of
titanium dioxide.
Treatment
The
diffusion process is one of the most common treatments performed on star
sapphires. In the general treatment applicable to faceted stones, a colouring
element called a chromophore is applied to the surface of natural colourless
sapphire, and the stone is heated to high temperatures for 7-8 days. This
results in the diffusion of the chromophore in the surface of the gemstone,
thereby making the colourless sapphire have a blue surface layer. The
appearance of such a sapphire becomes blue; however, the coloured layer is very
thin. The diffusion process is one of the most common treatments performed on
star sapphires.
Unusual Properties
Similar
to the Blue Sapphire, it has an aqueous inclusion in its makeup that creates a
refracted five-pointed star on the stone’s surface. This star is a focal point
in the gem. Recommended for people who wish to awaken or heighten their psychic
abilities. Star Sapphires usually have six-ray stars, but twelve-ray stars are
also known. Rarely, when sapphires are cut in cabochon, they can demonstrate a
cat’s eye effect. This effect displays a thin band of light down the centre of
the stone, known as chatoyancy. Works as a relaxing agent during times of
extreme physical exertion. Healers of the spirit and body are often drawn to
this stone.
Birthstones
A
Star Sapphire is given on the 65th wedding anniversary. It is also one of the
birthstones for the Zodiac signs of Pisces, Taurus, Virgo, and Sagittarius.
Usage
Rings,
bracelets, Pendants or lockets, necklaces, or other jewellery.
