1. Diamond

2. Ruby

Rubies, these stones with the blazing red color, are considered to be one of the most popular and sought-after stones in the entire world. They are mainly valued depending on the intensiveness of their color, their clarity, the cut, and carat weight. The best quality rubies are mainly mined at Myanmar also known as Burma, Though there are large deposits of rubies in Mozambique.

Different civilizations in the past have attributed special powers on this gemstone including its effects to the human body. It is believed that the stone can help with dreaming and sleeping, with healing of wounds, can help people live longer, improves eyesight, and brings more energy and vitality into your life. The hue continues to be popular in the market, and although Burmese lot material is easily obtainable, it is much sought after in larger and finer sizes.

Imitation rubies have been manufactured from the early 1900s, which can be a cheaper version of natural rubies. Thus, the creation of artificial corundum, including ruby, enables the use of this material in different fields, from gemmological purposes to applications within industries.

Ruby is one of the oldest and most famous gems, it is considered to be a symbol of passion and protection, as well as a talisman. For that reason, they are popular in fine jewelry, and their hardness and wear resistance make them wearable in daily use.

Traditionally it is reported that sapphire has a close bond with royal families and is believed to draw fortunes and blessings.

Thus, if a blue sapphire is assessed, the possibility of high price for the stone increases if it was subjected to some kind of treatment. For instance, a heated blue sapphire that is cheaper is more available, while an untreated gemstone is very valuable. That is why it is necessary to be cautious of such techniques as diffusion or glazing filling since after that, the desired jewel becomes almost worthless.

Sapphire is such a versatile gemstone that it can be categorized in many sub categories for the market. For instance, if one wishes to buy small size Blue sapphires then it is most likely that he has to get it from Madagascar. Another important factor that is also considered as a gemstone’s value is the quality; investor and collectors mainly focus on the gems that are in the excellent or near-excellent condition.

In the sapphire market, the high-clarity material can be overpriced while the slightly included material might be comparatively cheap, good opportunities for carefully selecting the buyer.

As mentioned earlier, uncut emeralds are not common; hence, they must go through certification from different laboratories and are expensive. The buyer preferences or behavior has slightly been altered by emerald treatment in the current years due to awareness.

In other cultures, emerald gems are not only utilized in fashioning jewelry but they also possess a cultural value in that they represent rebirth and fertility or fruitfulness among people.

This gemstone’s value depends on several oar, yet clarity plays a significant role in the light reflection so its color-changing capabilities. Alexandrites of ‘High Clarity’ classification are highly desirable and thus costlier.
