Yellow sapphire is a highly sought-after gemstone that has been treasured for centuries. It is valued for its beautiful yellow hue, excellent hardness, and durability. However, there are two types of yellow sapphire available in the market, heated and unheated. Heated yellow sapphire is treated with heat to enhance its colour and clarity, while unheated yellow sapphire is left in its natural state. In this article, we will explore the differences between heated and unheated yellow sapphires, including their appearance, value, and authenticity, to help you make an informed decision when choosing a yellow sapphire gemstone.
Heated Yellow Sapphire
Yellow sapphire is a precious gemstone that belongs to the corundum mineral family, which also includes ruby. The yellow sapphire is known for its beautiful yellow colour and excellent clarity. When a yellow sapphire is heated, its colour and clarity can be improved or altered. Heating yellow sapphire is a common practice in the gemstone industry. The process involves exposing the stone to high temperatures to remove any impurities or enhance its colour. The heat treatment process can result in a more vibrant and intense yellow colour, making the gemstone more valuable. The heating process is carefully controlled to prevent damage to the gemstone. The temperature is gradually increased and maintained for several hours until the desired colour is achieved.
The gemstone is then slowly cooled to prevent any cracks or fractures from forming. Heated yellow sapphires are widely available in the market and are often preferred over their unheated counterparts due to their enhanced colour and clarity. However, it is important to note that not all yellow sapphires are suitable for heat treatment, and the process can affect the value of the gemstone. When purchasing a heated yellow sapphire, it is important to seek the advice of a reputable gemstone dealer or a gemologist who can provide information on the quality and origin of the stone. With proper care and maintenance, a heated yellow sapphire can last for generations, making it a valuable addition to any jewellery collection.
Unheated Yellow Sapphire
Yellow sapphire is a precious gemstone that belongs to the corundum mineral family, just like Ruby stone and blue sapphire. It gets its yellow colour from the presence of iron and titanium in the crystal structure. The gemstone is also known as Pukhraj in Hindi. Unheated yellow sapphire refers to a natural and untreated variety of gemstones. This means that the stone has not been subjected to any heat treatment or artificial enhancement to improve its colour or clarity. Unheated yellow sapphires are considered to be of the highest quality and are highly valued in the gemstone market. Unheated yellow sapphire is usually found in Sri Lanka, Madagascar, Tanzania, and Thailand.
The gemstone is known for its brilliant yellow colour, which can range from pale lemons to deep golden hues. The colour intensity of the stone is a primary factor in determining its value, with brighter and more vivid colours being more valuable. The clarity of unheated yellow sapphire is also an essential factor in determining its value. The gemstone should ideally be free of any visible inclusions or flaws, as these can affect the stone’s transparency and brilliance. However, some minor inclusions are acceptable in natural gemstones and can give them a unique character. Unheated yellow sapphire is believed to have several metaphysical properties and is often associated with the planet Jupiter. According to astrologers, wearing yellow sapphire can bring prosperity, good luck, and success to the wearer. It is also said to promote wisdom, knowledge, and spiritual enlightenment.
