A gem or precious stone is a mineral, rock or material that once treated can be used in the making of jewellery. Its use goes back to antiquity when the jewels began to be used as a symbol of worship, power, exclusivity or ornamentation. Do you know what are the characteristics of beads that can increase or decrease its value in the market; to determine the value of a precious stone have to take into account different characteristics such as the degree of hardness of the same, which guarantees its strength and durability and consequently increases its value in the market.
When speaking of the hardness of a certain mineral, it is necessary to mention Friedrich Mohs who in 1825 established a scale with 10 reference minerals to which he attributed a certain degree of hardness. The scale begins with the talc to which is attributed a hardness degree of value 1 and ends with the diamond, considered one of the beads with a degree of hardness of value 10. The scale devised by Mohs was intended to demonstrate that a mineral can scratch to another mineral with a lower degree of hardness but not vice versa.
The same color, although it can also be found in shades of orange, yellow, green and even black. It belongs to the family of aluminum silicates combined with iron or magnesium oxide; hence, its famous reddish garnet color. Its name comes from the Latin granatum that, curiously, leads us to think that it defines its color; in reality and yet, it means grain. In the Bible, the garnet is mentioned. Because it is in large proportions in nature, its cost is quite low compared to the ruby, so it is used very often in jewelry as a substitute for it to achieve a cost reduction. It has a hardness of 7.5 on the Mohs scale.
These Beads are also known by all as Moonstone; it belongs to the family of aluminum, calcium, sodium and potassium silicates or their mixture. It’s possible color ranges from a transparent bluish to translucent white, but always presenting its particular iridescent brightness called adularity (blue and undulating and meandering reflections that seem to float when the stone is turned in front of a light source).Very famous in the time of the Roman Empire, when it was was composed of rays of the Moon. In addition to the hardness of the mineral, another factor that can increase or decrease the value of a stone is its color. Throughout history, it has been considered that many colored beads had healing properties, which is why they were especially demanded among collectors.
Emeralds, rubies or sapphires are considered the most desired gembeads along with diamonds Vivid, bright and unified colors can increase the value of the stone compared to others that have several shades. There are beads that have a characteristic color as is the case of Ruby due to part of its components such as iron and chromium. This gem of color owes its name to the word “ruber” from Latin and whose meaning is red. Another of the precious beads with a high market value and a characteristic green color containing chrome and vanadium is the emerald. Leaving aside the color, we focus on another important feature when analyzing a gem: weight. We must differentiate at this point the differences between size and weight. That a gem is larger than another does not necessarily mean that it is more valuable, since it can also weigh less than this one.
Semiprecious Beads and Precious Beads how are they different?
If you are fond of semiprecious beads, you have surely asked yourself these questions. What is the difference between a precious stone and a semiprecious stone? Why are they worth more than others? What is it that makes a stone belong to one or another group? We will try to answer them in this article, without going into very technical details, in a simple way. Diamond, ruby, sapphire and emerald are traditionally considered precious beads. What is known as the big four? When we speak of semiprecious beads we refer to a great variety of beads or gems that, throughout history, have been losing their consideration of precious beads for one reason or another.
It must be said that this difference between precious beads and semiprecious beads is already somewhat obsolete, since there are gems in the market that, even though they are not within these four large ones, can reach astronomical prices. And on the other hand, there are so few qualities in the market of those so-called big four that even the most humble quartz surpasses them in beauty, in tenacity and in merits to be worn as a jewel. So what is the correct classification? It is more correct to talk about precious beads and ornamental beads.
One carat corresponds to an approximate weight of 0.2 grams
The weight and degree of purity of precious beads is determined in carats (carat approximately 0.2 grams), a Greek word that alludes to the carob tree and whose seeds were used in antiquity to establish the weight and value of gems and the precious beads. Colors, brightness, transparency, scarcity, tonality, hardness, cut, weight, symmetry, components … in the evaluation process of any gem or precious stone, an exhaustive analysis of all the peculiarities of the piece is carried out, which will definitively establish its real value in a possible sales process in the market.
There are natural materials of organic origin -such as pearls, amber, coral, jet or to our regret the ivory- that, although they can be very valuable and receive gem honors, cannot be called precious beads or semiprecious beads or ornamental beads, because these three terms are reserved for the natural and inorganic solid materials that are minerals and rocks. We hope we have solved the questions with which we started this article and that it is now easier to understand the wonderful world of precious and semiprecious beads.
