What Quality Make A Gemstone Desirable?
Gems can be classified with the following characterstics.
- Beauty
- Colour
- Sparkle
- Reflection
- Refraction
- Dispersion
- Facetting
- Size
- Shape
- Durability
- Hardness
- Abrasion Resistance
- Rarity
- Natural
- Synthetic
- Fashion
Beauty - Optical Attraction
Most importantly things that a gemstone must be optically attractive , that can achieve in various style . It can be beautiful color ,can be sparkle through reflecting , refracting or dispersing light .So you can also classify the Optical attraction of the gem as .
1.Shape
2.Sparkle
3.Size
Colour
Color is the most important single gem characteristic .Ruby , Amethyst, Sapphire and Emerald having attractive color and are usually predictable to be translucent, Some for gemstone are also not be transparent. Such that Coral, lapis lazuli, cornelian and opal are beautiful and usually opaque.Colorless gems are less attractive. Though sapphire, spinel and quartz and other gemstones can occur in colorless varieties, they are usually quite uninteresting and looking awkward. Diamond is colorless but it can be rewarded as the precious stone.
The reason is that diamond is suitable as a gemstone because of the refraction and dispersion - .On the technical point of the view colors for a moment rather than colored gemstones.
High-preference colors, that will have high attention value.Such that Yellow have highest attention value .The test of the perception shows that any body can see easily yellow color rather than other like brown or the green.Blue is most likely the premier liking color, with red, purple and green following. Whatever the reason but most people likely wear a gems stone
Sparkle
Actually it’s necessary to consider why some stones sparkle more than others:-
• Reflection
• Refraction
• Dispersion
• Facetting
Let’s take these four concepts in turn, although as you will see there is some interaction between them. Reflection
Every stone has a specialty of reflecting the stone whenever the light thrown upon it .Every stone will reflect light from their surface. The reflective amount of the light depend on the surface reflectivity of the stone.The reflectivity is most comparable refractivity, factors such stone hardness affect its reflectivity, on the other hand partially though the ability of hard stones to accept a high polish.
Luster is the reflectivity of a stone at its surface .Refraction
Every Material reflects a light ( alter its angle) .So the amount at which light is refract can be determined as the special property of the gemstone that can be measure of the refractivity known as its refractive Index or R.I. On the other hand when the light passes through the various medium ,you can say its diffraction.
Dispersion
It is a difference between amount of the refraction of the different colors of the light. White light is also composed of the different color . A material which is highly dispersive split the light into the components and give its prism effect as like a fire.Faceting
If a gemstone has a many faces than the gems like more attractive and give more sparkles whenever a light passes through it.Size
It’s true that a big gemstone can be more beautiful as well as more desirable. A tiny or micro gems is less useful in making the jewelry so the gemologist
, either you can say that the big gems stone are most useful in making the jewelry.
Shape
The most fabulous gems stone size in the shape of the heart so its must be more desirable than the other shape. Some gems are usually in the certain shape and that type of the shape is must be desirable for making a jewelry .Some gems are also in the typical shape so they must be cut into oblong as well as octagonal shape. Like a Emeralds that must be cut to form an octagon also known as emerald cut.
Durability Instead of the beautifulness of the gems ,Its must be customary that a gem must be durable ,Like a gem Dianmond is very indestructible on the other hand some gems are very delicate. Its is a contradiction that a gemstone that is small must be delicate looking as well as strong Durability doesn’t means to say that durability is equal to hardness. So while choosing a gem always check whether or whether not gem is durable.
Rarity
According to the authors and jewellers rarity is obligatory or enviable for a gemstone. So gems must be beautiful and attractive as well as rare. According to Supply and demand frequently speak that rare objects grasp high prices. For example amethysts are often underrated in spite of their beautiful color, because they are slightly inexpensive.
The status value of the gems is increased by their rarity , Not even depend only on the
Visual value, even though there are stone collectors who understand the value of possessing rare and strange specimen whether beautiful or not. Every gemstone are not cheap as well as some gemstone can be keep as the undervalued. For example Diamonds must be million times than common than alexandrite. Natural, Synthetic or Simulant
Many person like only natural look of the gems stone. On the other hand
You can easily look forward for comparing such that the cost of the 1 caret diamond usually be £100 so we can reach on the conclusion that the there must be still demands for the natural products also.
You can easily imagine difference between natural., synthetic as well as simulated .First up you must clear your mind the not all simulated are synthetic or not even synthetics are simulates . Simulant is a a stone which appear as like , different stone, so that cubic Zirconia and ordinary colourless Sapphire can both be used to emulate or suggest diamond. A unnaturally produced diamond is a real diamond, you can not say as a stimulant for diamond. Artificial sapphire can be used to replicate alexandrite but can never replicate sapphire because it is sapphire.
Ancient Egyptians used to make a turquoise colored ceramic called faience in imitation of turquoise that has been invent near about 7000years .
Synthetic gemstones are comparatively latest. Synthetic ruby has been produced since before 1905, spinel from 1908, sapphire from 1911, and diamond from about 1950.
Fashion
The decision of the gems must be accordance with the fashion , means the gems that you are going for purchasing must be accordance with the style. Like Moonrock which looks very awkward and very rare to find but it can be considered as the fashionable as well as special gems stone , So most of the Hollywood actor like that gems. On the other hand Ivory is now out of dated .
Yellow and brown tinted diamonds can be rewarded as not much of the color to wear, but they are now rewarded as the full of the colors. It might be possible that the colored diamonds may be next jeweler fashion . Color diamond are now come in the various part of the world like in the England.
also you can find the most person are willing to purchase only De Beers because it is colorful Gem.
