The color of demantoid and other colored gemstones consists of three main parameters that determine their beauty and value
Do you know the important color parameters in demantoid?
These three items include: Hue, saturation, and Tone, and we will explain each of them below.
Hue is the first main parameter in the color of gemstones:
Hue is the main color that you will notice when you first look at a gemstone. For example, red color for ruby, green color for emerald or demantoid and blue color for sapphire. You can rarely find pure color in gemstones, which of course have a very high value. They usually have a secondary color. Secondary colors make the color of the stone come out of uniformity and purity and usually ends with (ish), such as Yellowish Green, which means a green color that has a yellow color around it. The purer the color, the more valuable the gemstone. For example, a pure pink ruby is more valuable than a purplish pink ruby.
Saturation is the second main parameter in the color of gemstones:
saturation which determines the vividness or intensity of the color of the gemstone. The more brown and gray colors in a gemstone The amount of primary colors is reduced and as a result the stone becomes less valuable and less attractive to the viewer. And on the contrary, the stones that have vivid colors have more value and are more beautiful
Tone is the third main parameter in the color of gemstones:
Tone: The lightness or darkness of the stone is called tone. which ranges from very light, to light, medium, dark and very dark. Sometimes a precious stone can be so dark that it can be seen completely black and only when it is placed under very strong light, the original color of the stone can be seen, of course, these stones are not so beautiful and dont have very value, and even very light stones They are not so attractive.
When the name garnet is mentioned, we mostly think of red color. But the Garnet family is very diverse. Garnet is available in red, brown, yellow, orange, green, pink and purple colors. Green garnets are very rare. Garnet is divided into 6 types: Pyrope, almandite, spessartite, grossular, andradite and uvarovite. Garnets have a cubic crystal shape but have different chemical compositions. Two types of grossular and andradite have green garnets.
Demantoid is the rarest type of garnet, which has many special characteristics. It means the highest refractive index (1.88) among all types of garnet and higher than tsavorite and very high dispersion (0.057), which is even higher than diamond. hewn demantoids in sizes below 1 carat are usually found, and above 1 carat with good quality cost up to several thousand dollars, and hewn demantoids above 2 carats and with very good quality are very rare
The unique and vibrant color of demantoid is highly sought after by those interested in precious and rare stones. so that in some cases even in medium darkness it has its own brightness.
Chromium in demantoid causes green color and ferric causes yellow color. Demantoids have a variety of colors. From dark green to yellowish green, in between these two colors there are other colors such as rich green, vivid green, medium green, yellowish green, brownish green.
The best demantoid color is a vivid and pure green color without any secondary colors.
Compared to other green and precious stones such as emerald and tsavorite, although they are more common and found in larger quantities, demantoid has surpassed them because of the three characteristics of high brightness, high dispersion and being very rare.
It is also highly sought after by collectors and great jewelers in the world.
