Sapphires are one of the most sought-after gemstones in the world, renowned for their enticing hues and impressive durability. They are one of the most cherished gemstones, often adorning engagement rings and other jewelry. You might be surprised to learn that not all sapphires are the same!
What sets them apart is whether they have been subjected to heat treatment or left in their natural and unheated state. If you are somewhat new to the vibrant world of sapphire gemstones and unfamiliar with these terms, this article is just for you!
In this article, let's delve into the differences between unheated and heated sapphires, shedding light on what you need to know before buying them.
Heated Sapphires
Heat treatment is quite a common practice when it comes to the gemstone industry. Many colored gemstones undergo heat treatment, and sapphires are no exception. The process involves exposing the stone to high temperatures to enhance its color and clarity.
Sapphires are typically heated above temperatures of 1200°C. This heat can help dissolve minor inclusions, intensify and improve color saturation, and remove unwanted color zones (color zone refers to an uneven distribution of color within a gemstone), making the gem more visually appealing!
Unheated Sapphires
Unheated sapphire, also known as untreated or natural sapphire, is prized for its rarity. These precious gems are coveted for their untouched and natural beauty. As the name suggests, unheated sapphires are those stones that have not been subjected to any form of artificial enhancement and remain in their original state as they were found on the earth. They are admired for their inherent purity as they exude a sense of authenticity.
Unveiling the Difference Between Unheated and Heated Sapphires
Color
One of the most significant differences between unheated and heated sapphires lies in their color. Heat can intensify and boost the color of a sapphire, making it more appealing to the eyes.
Unheated sapphires, on the other hand, boast colors that are entirely natural and unaltered by heat.
Rarity and value
Unheated sapphires are a true gemstone treasure. No wonder they are highly coveted by gemstone collectors and lovers. Since they are a natural rarity, they often fetch higher prices than heated ones. The rarity of unheated sapphires, especially when it comes to larger sizes and exceptional colors, plays a vital role in boosting their value. It adds an extra touch of allure that you can't resist!
Clarity and Inclusions
Another factor to consider is clarity. Heat treatment can help remove or diminish inclusions and flaws in sapphire gemstones, making them appear more polished and transparent. However, unheated sapphires may have a higher chance of retaining these inclusions. Nonetheless, many buyers find these inclusions appealing, as they can serve as a testament to the gem's authenticity and unaltered state.
Final Thoughts
Choosing between heated and unheated sapphires ultimately depends on your preferences. If you have a high budget, and value rarity & authenticity, unheated sapphire is the ideal choice. However, if you are looking for a sapphire gemstone with an intense hue and high clarity at a relatively affordable price, heated sapphire is the way to go.
Sapphire, whether heated or unheated, possesses a timeless allure that can mesmerize anyone. You can find high-quality loose sapphire gemstones as well as jewelry pieces at GemsNY!
