CABRHA diamonds chooses the most admirable diamonds for You


Symbol of rarity, uniqueness and beauty is one of the most principal elements in the nature - carbon in a specific crystalline form. Carbon atoms are connected by solid links in such a cubic crystalline lattice.


Diamond Occurence

Diamond is a crystalline form of carbon, which is converted in the conditions of extreme temperatures and pressures. Crystallization of diamond in cubic system takes place under extreme conditions, where the temperature is higher than 1300 °C and the pressure exceeds 70,000 kg per square centimeter, which corresponds to conditions reached 100 to 200 km below the earth surface.


History Of Diamonds

It is likely that the diamonds came to Europe for the first time in the 4th century BC, when they were brought in by Alexander the Great from one of his expeditions. It is said that when Alexander the Great reached the point of the valley whose bottom was full of precious stones, he also saw at the bottom of the valley giant snakes guarding these gems. Alexander, however, succeeded in cheating them and won the gemstones.We already know that one hundred years later the diamonds were already subject of trading.


Diamond Mining

Rarity of diamonds is enhanced also by the immense difficulty of obtaining them. Approximately 160 million carats (32 tonnes) of diamonds at a price of about $ 13.4 billion are mined yearly. Only a small fraction of this volume is designed for jewellery industry, the majority is used in the industrial sphere. Top quality polished diamonds represent about 3% of the world production.The supplies of diamonds are significantly diminishing every year, while the demand for them is rising, which is the cause of continuous rise in the prices of diamonds.

Synthetic diamonds substitutes


Cubic Zirconia - is similar to diamonds due to its optical properties and hardness, which is close to the hardness of ruby or sapphire. It is available in any color and only for a fraction price of genuine diamonds. The strong similarity with diamond is  understandably tempting their intentional substitution, because only an experienced jeweller can quickly and reliably distinguish between these two materials.


Moissanite - looks and features like diamonds - was first discovered in Arizona by the Nobel Prize winner Dr. Henri Moissan. This mineral had properties of  absolutely brilliant shine and unbelievable hardness.


Thanks to these features Moissanite started to use in jewellery as a substitute for diamonds. Due to the limited availability of natural moissanite, there were invented by the company. Charles & Colvard synthetic Moissanites , which are extensively used in the jewellery industry.


Based on the above mentioned facts you are advised to consult by estimation of investment stones experts in this field, who have technical background, enabling 100% identification of absolutely genuine diamond from counterfeits..
