Anyone needs to understand the difference between a precious and semi-precious stone, its meaning, and properties. But it is even more important for the merchant since that will depend on the commercialization value of the piece.

Currently, the precious stones are:

• The diamond.
• The Rubi
• Sapphire
• The Emerald

This is a traditional classification that differentiates morganite and has been maintained over time. The difference between precious and semi-precious is based on the differences in their main characteristics: the hardness, rarity, and perfection of the gems.

One of those reasons is the scarcity or difficulty to locate them in nature, within this category we only find four gems and they are: white diamond, ruby, emerald, and blue sapphire since they are more difficult to find. There are few mines that currently they are of these pieces.

Durability is also an important property and characteristic of these valuable stones. For them, there is a measurement scale known as the Mohs scale that goes from 1 to 10. It allows measuring the birth stones ability to withstand scratching, abrasion, penetration, or cutting by other material.

The Mohs scale dated from 1812 and was designed to determine on a numerical scale how resistant these minerals called gems are, to the scratching or cutting of cubic zirconia—turns out that the diamond is the only one that occupies the 10th position in the said scale.

In this scale, other materials allow in a laboratory test to determine the scale of each mineral that we know. However, it is true, the scale is over 200 years old and is not a truly infallible method, smoky quartz is taken as a reference to categorize each mineral, along with other tests to be performed.

Another of the characteristics and properties is the beauty and perfection of carnelian gems, and almost all gems have them in their way and to their measure. Still, for the simple fact of being created by nature, they are beautiful, and man can even correct any imperfection they have without affecting the rest of its characteristics.

Properties and meaning of semi-precious gems

It is important to know what are the characteristics and properties that a zircon must have to consider as a precious, semi-precious, or synthetic stone.

Durability

The strength of the blue sapphire is also an important characteristic property. However, this does not mean that it must be resistant to everything. It is measured how much resistance this stone has.

Rarity or difficulty getting

The fact that the kyanite stones are obtained from nature and cannot be "duplicated" by any human-machine with the same characteristics as the original makes the difficulty of obtaining them not only economical but also of general accessibility.

Falsification

Counterfeits, although it sounds like a topic outside the law, is not in all cases, since due to the same high quality and demanding characteristics of the originals, the market has allowed lab created diamonds to be created with other materials and even with similar details. Imitations of stones such as diamond, emerald, among others to be marketed at lower costs and have the same artistic purpose as the real ones.

There are many ways to classify precious and semi-precious stones; one of them is to do it by its origin:

• Natural or original gems
• Synthetic gems those that are made in a laboratory, the product of man's intervention
• Composed by the union of others
• Gems reconstituted  by heat and pressure, for example, tortoiseshell
• Imitation Gems
• Glasses
• Natural pearls, those that are generated by mollusks such as oysters

Color sorting

One of the biggest attractions that a blue topaz as its color, the visual effect they cause is inevitable, and many of these people identify themselves in such a way that they adopt certain stones as talismans only because of their color.

Traditionally, there are some very well-known stones exclusively for their color, such as sapphire (blue), emerald (green), garnet stone (red), among others. Still, in another category of colors, we can find sapphire or garnet itself since be a source stone black mineral, its color can vary but retain the rest of the characteristics of the base stone.

 Red: They are not as common as we think, despite being a primary color, the stones that we can place in this category is ruby, whose name.

In Latin, ruber means red, garnet, and spinel, to name three of the most common. But it is important to note that there are other shades such as a red-orange. It may well be located in this classification or in the one we indicate as orange. corundum red color comes mainly from the iron content in the stone.

Blue: When we think of blue gemstones, a quite high percentage of people will quote us the sapphire, since it is the best known blue stone, but there are more than 35 gems within this blue color range, including black onyx, the same star sapphire, among other.

Greens:  the most traditional and most famous chrysoprase of all is the emerald, whose name comes from the Persian language and means greenstone. But believe it, or not there are more than 50 types of gems within the green color range, including turquoise stone and a type of green sapphire.

Yellow and/or gold: Within this category, we can find a type of yellow sapphire, but the most common is citrine. We also find topaz, agate and amber, and a little more than 15 lesser-known gems.

Violet and/or Purple:  Amethyst is the representation of the violet color in the list of precious stones, accompanied by about 12 more types of them, including a variant of diamond and sapphire in this hue.

Orange: This color is less frequent in gemstones; in fact, its list is somewhat shorter than the rest; however, some such as thickened garnet are still counted.

White: Diamond is king in this category, as are quartz and zirconia, considered colorless gems or aquamarine color gems.

Gray/Silver: Undoubtedly, this color range is the least frequent in a precious stone. However, there are two or three that are well known as aquamarine stone, such as pearl, mother-of-pearl, and moonstone.

The world of precious stones is a vast and fascinating area. But sometimes it is complex to recognize the quality of the gem and especially its value!

Bad-natured people very often use the naivety of the buyers by selling them low-quality Corundum Gemstones at exorbitant prices. Although knowledge of gemology requires years of study in addition to the use of technical instruments, it is no secret to access the knowledge of the basic rules.

Tip 1: pay attention to the color of the gemstone

Its color determines 50 % of the value of a lab emerald. The golden rule is neither too light nor too dark. A beautiful gem must have a balanced and harmonious color.

Harmony of colors

Its color should be the same, perfectly visible throughout the lab created emerald - this does not apply to Opals - No angle of the gemstone should be more shaded or lighter, the color should be uniform.

Ideal color?

Here is a yes and a no. There are remarkable colors such as the famous lab grown white sapphire, Kashmir Sapphire Blue or Ruby Red "Sangre de Paloma" but we must agree that the ideal color should correspond to each type of precious stone.

For example, the Peridot, its "perfect" hue, should be a beautiful lime green, softened by slightly yellow tints, well balanced, clear, and bright. In the case of the created emerald, the green must be very intense with reflections of blue.

A hydrothermal emerald too light will have less value than an emerald with a well-defined color and higher saturation. And staying in the green gems if we take the Diopside, its green is neutral, powerful, and very bright.

Should we then acquire only perfectly colored gemstones?

Logically not! Do not forget that ultimately the perfect color is the color that you like the most. Take the case of White Gemstones. At the moment, the most popular is the Amethysts of Uruguay with intense violet color, well-marked, with dark blue reflections.

Clients have every right in the world to think that way because color perception is subjective, and it has to do with the personal taste of each one!

Tip 2: Pay attention to the weight of the gemstone  

It is wrongly believed that the total carat weight of emeralds for sale determines its value, that is, 10 carats of Diamond is 10 carats of Diamonds. Attention.

Value not proportional to weight

The dimension of the emerald stones for sale will then be of great importance when evaluating its price. But, attention, its value will not increase proportionally to its weight.

All weights are not equal

Here we have another factor to consider. Russia offers an incredible quality of Emeralds of a superb color. Russian Emeralds are therefore highly coveted by collectors due to their exalting color. But to buy emerald stone, they are found only in small dimensions!

It is very rare to find Russian Emeralds of more than one carat. For this reason, a 2-carat man made opal will cost more than a 3 carat Brazilian Emerald. Scarcity plays a role in the price of the Precious Stone.
