When you think of a sapphire, the gem stone that immediately comes to your mind is a deep blue stone, right? But sapphires actually have lots of different shades other than deep blue, and this is due to some minerals that are found in some sapphire stones. A sapphire could be yellow, green, orange, pink, or even black. This is why you have to know how to evaluate sapphires.
Evaluating sapphires is a bit similar to evaluating diamonds. Here are some tips on how to evaluate sapphires:
- Examine the color of the stone. Since you already know that sapphires can come in different shades, you should examine if the color of the sapphire is whole or if it is a mixture of different colors. If the stone is a mixture of different colors, it is considered as less valuable whereas if the stone is made up of only one color such as deep blue, it is considered as very valuable. Also consider the hue of the stone. If the stone has only one color, you have to check on its hue. If the color is a light blue, it is considered as less valuable compared to a stone with a deep hue of blue.
- Scrutinize the stone’s brilliance. You should examine it under a magnifying glass. If the sapphire has no scratches or flaws, then it is considered flawless. However, naturally flawless gem stones are a rare find. But even if the gem stone has some flaws, it is still considered a good find since a jeweler can cut the stone in such a way that the flaws will be eliminated, thereby showing the full brilliance of the sapphire.
- Check the size of the sapphire. Even though sapphires are also measured by carat similar to a diamond, a sapphire measuring a single carat is larger than a diamond of the same carat. This is the reason why you should not compare the size and weight of a sapphire to a different gem stone. Instead, ask the help of a jeweler and a proper weighing instrument in determining the size and weight of a sapphire.
- Determine the origin of the sapphire. If the sapphire was acquired from a mine, you should know where it came from since its value is also determined by its origin. A sapphire from the caves of Burma is more valuable compared to a sapphire that originated from Sri Lanka even if they have the same carat measurement.
- There are gem stones that were created in a lab, and if that is the case, the origin does not matter. Instead, you can treat the stone in the lab to make the stone darker by heat treatment, and the result is almost the same as a natural stone that came from the mines. However, a lab created and treated stone costs less than a natural stone.
Whatever type of sapphire that you want to acquire, you should have the skills on how to evaluate the stone so that you will know how to choose the right sapphire. If you are not sure, it is better to ask the opinion of a professional jeweler.
