Managing Director of Chamal Gems Mr. Chamal Perera

Mr. Chamal Perera says that “Precious gemstones contain a message from the heart of the earth we can admire its elegance, but its true meaning is what scientists are saying about the intense forces that formulate it well below the surface.”  During an informative interview, he added that the valuable stones or gems are many, and passion and dedication are necessary for study and classification. In addition to knowledge, tools for differentiating them are necessary. Chamal Gems’ MD shall say a lot to show the fascinating world of precious stones in this article. In the making of jewelry, a precious gemstone or a diamond is used. They can come from three origins:

• Geological rocks and minerals: among which we will speak more about sapphire, emerald, aquamarine, and diamond.
• Vegetables: as amber or jet
• Animals: like pearl and coral. After it has been completed it is cut into a precious stone or gem, graven and polished. Gemology is the discipline of science that studies it and the people who deal with these stones are gemologists. The research consists primarily of learning to distinguish the chemical, physical and optical properties. The attributes of precious gemstones are:RarityWe rely naturally on what nature gives us. All of them are different, nobody is the same. This is probably the most common feature and appears to be homogenous when manufacturing. Today, many equal parts of a commodity are made inexpensive, rendering exclusive and differentiated. 

  Hardness

  Gemstones should have a high hardness when used in jewelry. There is a table called The Mohs table which is graded for gemstones according to hardness

  Size

  This is how we display the optical characteristics. The development and quality of the size are obvious in both small sizes and, of course, large sizes, where a thorough study is carried out before stone is applied. Sizes such as glow, baguette, princess, goat, oval, heart are different. The carving or steelmaking industry is very precise and the pace of many people is a more conventional technique where more natural stones and new, precise, and slower cutting are used for more value.

  Color

  It’s the main attribute for us to love a gem without a doubt. Typically you associate gemstones with one hue, but others do not enable us to recognize them, in many cases and because of the variety of colors. All kinds of colors and intensities can be found.

  Transparency, brightness

  This feature highlights color, we call it also crystallization, the inner force of the color transmits, to put it another way.

  Optical effects

  They separate the gem from each other. It is seen without the need for a glass lens with the naked eye and is based primarily on color schemes and adjustments. Opalescence, labradorescence, star effect or cat’s eye effect can be found

Types of Precious Gemstone

The word precious and semi-precious stones have been revoked and can therefore not be used by the Regulatory Council (CIBJO). The explanation for this is that in fact there is no such distinction. All the gems are valuable and extraordinary, which has been made more by value than by quality. An example is that there are extremely low-quality rubies and excellent aquamarines, so the mistake was corrected and all precious stones or gems should be called as follows:

Organic Gemstones

They are precious natural stones. This is the key attribute of a natural product. The interpretation of the term is not universally correct. Most of them are cut minerals, but biomass is also called natural gems in jewelry. Some of the examples are coral, gold, jet, or pearls. The light, color, and showiness of jewelry are another common denominator.

The therapies for natural gems are an important thing to remember. Heating, dyeing, and filling cracks are the most common treatments. These treatments enhance and support optical characteristics. Particularly because the value of a jewel changes significantly in some cases, this is significant. The existence of inclusions is another basic idea. Natural gems have cavities in which other minerals, liquids, or gases can be found.

The inclusions may also be seen with the naked eyes but the magnifying glass or microscope must be used to decide exactly. In certain cases, including emeralds, we can decide their country of origin based on their inclusions.

Synthetic Gemstones

They are artificially produced but with the same physical, optical and natural characteristics. It means you need an expert gemologist who carries out a gemstone test to distinguish them. The two primary instruments we use are the refract meter to calculate the refractive index and the stone. A microscope with inclusions to assess and corroborate the treatments

Imitation and Artificial Gems

This section includes two definitions:

Artificial: This is a substance made by humans so there are no properties in nature. We look like natural gems but their composition is different from both chemical and physical. They are crystalline glasses that are formed by fusion. Zirconium, which can be in all colors, is the most common. Swarovski glasses are other artificial jewels.

Imitation: this term involves synthetic and artificial gems that are used to mimic higher value gems. Imitation: As an example of aquamarine, for instance, blue topaz is used. The imitation of Paraíba tourmaline is also used for apatite.

For artificial gemologists, it is easier to classify them, because their features are completely different.
