Rare gemstones are especially valuable on the market. Today we’ll look into why this is the case and what unique stones you can look out for.
Factors affecting the value of a stone
- Rarity
One of the key factors is the rarity of the stone in nature. For example, large yellow diamonds of 10 carats and above with high characteristics (4Cs) are considered rare and unique, making them especially valuable in the market.
- Clarity and Transparency
The fewer inclusions a stone has, the more valuable it is. A whole grading system has been developed for diamonds (clarity of the stone, quality of cut, degree of imperfections and total weight), by which it is easy to determine how clean and clear a stone is.
- Size and weight
Stones of larger size and weight (measured in carats) are usually worth more. However, it is important to balance size with quality. For example, a smaller stone with high characteristics may be worth more than a larger stone with some flaws.
Rarity and historical significance
Some stones are given added value due to their historical significance or their association with famous personalities.
For example, stones that were once part of royal collections or belonged to famous monarchs may be worth much more.
Stones with unique characteristics
Some gemstones have unique characteristics that make them exceptional and expensive.
- Alexandrite
One of the rarest stones, it is known for its ability to change color depending on the light: from green in daylight to purple in artificial light. This effect makes alexandrite incredibly valuable, especially in stones with bright and saturated colors. A clear color transition from green to purple/burgundy is especially prized.
- Orange Diamond
Orange diamonds are considered incredibly rare and expensive because of their unique rich color.
- Paraiba Tourmaline
This bright blue or green tourmaline, mined only in small areas of Brazil and Africa, is considered one of the most expensive and beautiful tourmalines in the world. Its vibrant neon color and unique hues make it one of the most sought-after stones among collectors.
- Mahenge spinel
In recent years, there has been a high demand for spinels from Tanzania and Burma. It is there that red, incredibly popular trending spinels are found, which have increased in both demand and price relatively recently.
Conclusion
So, many factors influence the uniqueness of a stone and its value. If you are contemplating the purchase of a stone and want to not only invest money in it, but also get a valuable and special stone that will become your treasure, we advise you to pay attention to the rare stones that we talked about today.
