MGTL Certificates & Importance
If you want to buy a gem, you’d prefer to buy a certified one, correct? And it makes much sense since they don’t really come for the price of candies.
Since there is no internationally accepted grading system to grade coloured gemstones, there is also no appropriate answer on how to grade or analyze a gem.
Typically a Gemstone’s analysis would include the below-mentioned points:
- Determination of its origin (synthetic or natural)
- Information about the shape, colour, transparency, cut of the stone
- Important data like measurements, weight, etc.
State of the art gemological equipment and advanced skills are used to determine these characteristics.
Let’s go through a Gem Report for a better understanding.
Now why all this information becomes important is because it affects both the financial value as well as its durability and appearance. Thus we recommend you to take all this information into account before buying any gemstone.
There are situations when this information becomes all the more important for example handling the stone with extra care when treating it to a significant degree.
Information such as its origin is not very easy to determine as only a select few laboratories have access to such advanced equipment.
Thus information that should be included in such analysis reports are :
- The authenticity of the stone (Natural or Synthetic)
- Treatments or enhancements performed on the gemstone
- Weight (in Carats)
- Colour
- Style of Cut
- Specific Gravity (can be optional)
- Refractive Index (Not necessary)
- Name -: Name
- Report Number -: Helps to keep records.
- Species -: It represents the mineral species from which the Gemstone is formed.
- Weight:- Measurement of weight in grams (gm).
- Shape/Cut:- It represents the predefined cut/shape of the Gemstone
- Color:- It represents the color of the Gemstone.
- Refractive index:- In gemology, the refractive index is one of the chief means of identifying a gemstone. It is measured using an instrument known as a refractometer. The refractive index (often abbreviated RI) is an optical property that refers to the ratio of the speed of light in a vacuum to the speed of light through a transparent medium.
- Specific gravity :- is a way to express the relative density of a gemstone. It is measured as the ratio of the density of the gemstone to the density of water. It is expressed as a number that indicates how much heavier the gemstone is compared to an equal volume of water.
- Hardness:- The ability to resist scratching, nothing more. The Mohs scale of mineral hardness was created by the German mineralogist, Friedrich Mohsin 1822. It is used to measure the relative hardness or scratch resistance of various minerals on a scale from one to ten.
- Dimensions:- The measurements we provide are intended to represent a gemstone’s length, width and depth (L x W x H) in millimeters.
- Microscopic:- It represents the internal gemological characteristics that are revealed under the gemology microscope. These characteristics can help to determine if a gemstone is natural, synthetic, or treated.
