Pricing Insights of White Star Sapphire Stone
The price of original white Star Sapphire typically ranges from INR 1500 per carat to INR 70,000 per carat. It can further vary based on key factors like origin, clarity, colour, carat weight, and cut quality.
Factors Affecting White Star Sapphire Price
From rarity to quality, a lot goes into the pricing of a gemstone. Here is what drives these prices:
Origin
They come from some of the exotic corners of the world, such as Sri Lanka, Canada, Thailand, Myanmar, India, Vietnam, and Cambodia. The best ones are from Sri Lanka (Ceylon) and Myanmar, providing a well-defined star pattern and stunning clarity. Remember, origin is an important factor, highlighting the superior quality.
Colour
A uniform white colour, whether transparent or milky, enhances value. Any uneven zoning or blotchiness reduces the visual appeal and price.
Clarity
They are usually translucent; therefore, pieces with minor silky inclusions are considered authentic. However, the inclusions that obstruct the visibility of the 6-rayed asterism or lower the hues reduce the value of the stone. The golden rule? The clearer the appearance of the star, the higher the white Star Sapphire value.
Carat Weight
Like all gemstones, the size of the gemstone also determines its price. With the increase in carat weight, the visual appearance of the asterism and rarity of the stone also increase, making them more expensive. The price per carat tends to rise significantly between the 0.5 to 1 carat range and even more between 1 to 5 carats.
Cut
These gemstones are cut in an en cabochon shape with very high domes to deliver the proper visibility of asterism. The best cabochon Star Sapphire has even roundness, a centered star, and no weight below the girdle.
