A natural star sapphire stone is distinguished by its unique star effect. They are rare in nature and even rarer in fine quality. Therefore, having a basic knowledge of the important factors is essential to judge the quality of star sapphire gemstones. The quality of star sapphire largely depends upon its origin, color, strength of star effect, clarity and cut. Most of the star sapphires either lack clarity and good color saturation or strength of star effect. Therefore, a genuine star sapphire that ranks profoundly in the top end of these three quality checks, is considered as the finest gem.
– Star Sapphire gems are found dominantly in Sri Lanka (Ceylon), Myanmar (Burma) and Thailand. Some gem-quality star sapphires have also been discovered in India, Brazil, Cambodia, Nigeria, Madagascar, United States (Montana), Zimbabwe and Tanzania etc. Amongst all origins, Burma star sapphire and Sri Lankan star sapphire (Ceylon star sapphire) are regarded the finest quality gems because they lack distracting inclusions and exhibit a well-defined star effect. Black star sapphire Thailand is popular for its unique golden rayed star effect. (most star sapphire exhibits a white or silvery star).
– Star sapphire color is one of the major quality determinant. Its color ranges from blue to various tones of pink, black, orange, purple, gray etc. The intensity and color distribution also affect the quality of a star sapphire gem. The most desirable color is the vivid, intense blue. Amongst the natural blue star sapphire, the cornflower blue star sapphire and royal blue star sapphire are considered highly sought-after color varieties. In contrast, a light blue star sapphire or gems in other paler hues are comparatively less valuable.
Strength of the Star effect – Ideally, the star-like effect in the star sapphire stones should be bright, intense and perfectly centred with nearly equal ray length. The star sapphire natural stone with faintly visible, broken rays are of relatively lower quality.
– Clarity in star sapphire is a tricky aspect. All real star sapphires are expected to have some degree of inclusions. They are semi-translucent to opaque due to the presence of perfectly aligned microscopic needle-like rutile inclusions that are responsible for the star phenomena and velvety feel. However, some clarity-distracting factors like mineral inclusions, milkiness and visible color zoning can negatively affect the gem’s quality and price.
– A proper cutting and polishing of the Star sapphire loose stone is essential to obtain a centrally located, clearly visible star effect. The rough Star sapphire is mostly cut and polished in cabochons (non-faceted, polished gems in round or oval shape) to obtain the best star on the smooth surface. Star sapphire cabochon in perfect round or oval shapes are quite valuable. The star sapphire loose stones commonly have slight uneven tops or bottoms. This is often done to retain maximum weight and obtain a properly oriented star.

Strength of Star effect
– A bright and well-defined star is highly sought-after but is hard to find. So, a natural star sapphire value will increase for stones with a perfect star. Some 12-ray star sapphire (normally it has 6 rays) or double star sapphire (two stars on the same stone) also exist but they are highly rare and precious.
– Amongst all the Star sapphire colors, Blue star sapphire value remains the highest due to its rarity and high-end beauty. Pink sapphire stone price and black star sapphire cost also reflect their rarity and popularity in the trade. Apart from the hue, the Star sapphire’s value also depends on the tone and saturation of the color. Generally, deeper, more saturated and uniform is the color, more will be the Star sapphire gemstone value.
– Almost every Star sapphire naturally possesses silk or microscopic needle-like inclusions (that produces the stunning star effect) and are nearly opaque. These tiny inclusions lend a highly desirable vitreous silky shine. The price of star sapphire majorly drops due to presence of excessive color zoning and high volume of the value-decreasing mineral inclusions. The rare star sapphires with fine translucent or semi-transparent body and sharp star effect are usually expensive.
– A raw star sapphire stone is mostly cut and polished in cabochon. Even the expert gem cutters handle the uncut star sapphire very carefully to obtain a perfect, centrally located star effect and retain maximum weight. Poor polishing and uneven domes can reduce the beauty and star sapphire stone value in the market. The well-polished blue star sapphire cabochon always demands a cost for quality.
– Due to the rarity factor, large size gemstone draws a good value and star sapphires are not different. Fine quality, unheated and untreated big size star sapphires can fetch a very huge premium in the gemstone market. Small size specimens are relatively more affordable.
– Buyers Beware! When shopping for star sapphires, be very cautious as some cheap synthetic star sapphires (lab created star sapphires) are also available in the market. These artificially created star sapphires may have a perfect star, impeccable clarity and excellent color which is good enough to deceive an untrained eye. A natural, unheated star sapphire often contains inclusions and rarely forms an extremely sharp star. It is not worthy to pay a huge amount for a cheap synthetic stone.

Despite its perfectly even color, exceptional clarity and sharp eye effect, a Lindy star sapphire price value remain substantially low. In the market, Lindy blue star sapphires are more popular for jewelry making purposes. Therefore, a Blue Linde star sapphire price may be slightly higher than other color varieties.
On the other hand, Diffusion star sapphire is the natural star sapphire that undergoes the diffusion treatment which is done to enhance the asterism or star-effect in the sapphire gemstone. This treatment doesn’t affect the star sapphire physical properties. But, unlike natural star sapphire gemstone, a diffused star sapphire cannot be polished or recut for the second time because the treatment persists only on the surface of the stone.
