The 100% Certified Natural Star Ruby (Surya Kant Manik) weighing 4.87 Carat (Approx. 5.35 Ratti) is an exceptional natural gemstone displaying the captivating optical phenomenon known as asterism.

This gemstone is a Natural Ruby that is Untreated and Unheated. Its natural colour, internal crystal structure, inclusions, and star effect have been preserved exactly as nature created them over millions of years.

What Makes Star Ruby So Special?
Star Ruby is among the rarest varieties of natural Ruby. Its most remarkable feature is the naturally occurring six-rayed star produced by microscopic rutile inclusions aligned inside the gemstone during its formation deep within the Earth.
Unlike faceted Rubies, Star Rubies are fashioned into smooth cabochons, allowing the natural star to appear clearly under sunlight or a concentrated light source. Every star pattern is unique, making no two Star Rubies exactly alike.
Untreated & Unheated Natural Ruby
This gemstone has never undergone heat treatment or artificial enhancement. Its colour, inclusions, transparency, and optical characteristics are entirely natural. Untreated Rubies are appreciated because they retain their original geological identity and are comparatively scarce in the marketplace.
The naturally occurring inclusions inside this gemstone are not defects but evidence of authentic natural formation over millions of years.

Under Uniform Light source Under ordinary multi light source.
An asterism or a star effect in a gemstone is an optical phenomenon displayed by some rubies, sapphires, and other gemstones (e.g. garnet, Rose quartz, diopside, spinel) of an enhanced reflective area in the shape of a 4 to 6 ray "star" on the surface of a cabochon cut from the stone. The cabochon cut can be Oval, Round or any other shape.
Gemstones that exhibit special optical phenomena, including asterism (the star effect), chatoyancy (the cat's eye effect), adularescence (shimmering light) and iridescence (the rainbow effect) are categorised as phenomenal gemstones.
Because these phenomenal gems are fairly rare, they naturally attract the attention of rare gems collectors are priced much higher than their normally available counterparts.
