Yellow sapphire stones are been cherished for a long time due to their fascinating hues. Still, it is difficult to find a difference between a natural gem and a treated gem. A keen eye is required to distinguish between the two. In this blog, we will discuss the unknown things behind authentic sapphires and also, get to know what the difference is between heated and treated sapphire.

To know how rare yellow sapphire is:

Naturally occurring original Pukhraj stones seem fascinating due to their rarity in nature. More than a million years ago, they formed under the earth. There is a vibrant Colors spectrum in them, which gives you a tench of lemony yellow to rich Canary tones. It’s a pride in their natural beauty. If no artificial treatment is done with these gems, they exhibit a unique characteristic that makes them different from other treated sapphires.

Presence of Inclusions: Nature’s Fingerprint:

One of the ways in which a natural yellow sapphire gemstone can be distinguished from a treated one is through its inclusions. The presence of this internal feature is said to be “nature’s fingerprint.” This “nature’s fingerprint” is a valuable clue about the origin of sapphire. During the journey of their geology, it is proven that these natural sapphires can have minute crystals, also known as mineral needles, in them. However, if you talk about the treated sapphires, they may be deficient in such a distinctive inclusion, and they look totally different when displayed.

Intensity and Color consistency:

When we talk about the natural Original Pukhraj Stone, there is a consistent colour distribution. However, in treated gems, they may show some irregular tones, and it is due to the artificial treatments on them. The heat treatment given to the sapphire is very common, and it is due to raisin increasing the intensity of the colour, but it results in a less uniform appearance. The reliable sapphire has a rich intensity overall in the gem, and it radiates a natural shine that fascinates the owner of the gem.

To analyse the cut and polish:

The reliability and authenticity of a 3-carat Pukhraj stone or 7.25-carat yellow sapphire can also be revealed by the craftsmanship done by the gem cutter. To enhance the unique feature of the gem, the natural sapphire is usually cut in such a way that its inherent beauty is enhanced. If we talk about the treated stones, one can observe the irregular cutting or polishing.

Examining the Certificate of Authenticity:

Always prefer to have a certificate of authenticity checked if there is any doubt. If the sapphires are issued from reputable gem laboratories, they provide a detailed report about the gem’s origin, its characteristics, and the treatments done on them. Make sure that the certificate is issued by a recognized and reputed authority, as it confirms the natural status of your yellow sapphire gemstone.
