How do you get crown gems? This question often arises among those who are passionate about collecting precious stones or those who simply want to understand the process behind the creation of these dazzling jewels. Crown gems, also known as the “big four” of gemstones, include diamonds, rubies, sapphires, and emeralds. Each of these gems has its unique characteristics and origins, making their acquisition a fascinating journey. In this article, we will explore the various methods and sources for obtaining these exquisite crown gems.
Crown gems are formed deep within the Earth’s crust over millions of years. The process of their formation involves the combination of heat and pressure, which results in the crystallization of minerals. The most common sources of crown gems are mines located in countries with geological conditions conducive to their formation. Let’s delve into the specifics of each gem and how they can be obtained.
Diamonds
Diamonds are the hardest natural substance on Earth and are formed under extreme pressure and temperature conditions. The primary sources of diamonds are located in Africa, Canada, Australia, and Russia. To obtain diamonds, miners use a combination of open-pit and underground mining techniques. Once the rough diamonds are extracted, they are sent to cutting and polishing factories where they are shaped and faceted into the beautiful stones we see today.
Rubies
Rubies are a variety of the mineral corundum, with red coloration due to the presence of chromium. The most famous sources of rubies are located in Myanmar, Sri Lanka, and Madagascar. Similar to diamonds, rubies are mined using both open-pit and underground methods. After mining, the rough rubies are sent to gem-cutting factories for processing.
Sapphires
Sapphires are also a variety of corundum, but they come in a wide range of colors, with blue being the most common. The primary sources of sapphires are Australia, Madagascar, and Sri Lanka. Mining for sapphires involves searching for alluvial deposits or mining kimberlite pipes, which are volcanic rock formations that contain sapphires. Once the rough sapphires are mined, they are sent to cutting and polishing factories for further processing.
Emeralds
Emeralds are a variety of beryl, characterized by their green coloration, which is due to the presence of chromium and vanadium. The most renowned emerald mines are located in Colombia, Zambia, and Brazil. Mining for emeralds is a complex process that involves searching for emerald-rich veins in the Earth’s crust. The rough emeralds are then sent to cutting and polishing factories for processing.
In addition to mining, crown gems can also be obtained through various other sources. These include gemstone dealers, auction houses, and online marketplaces. It is essential to purchase crown gems from reputable sources to ensure their authenticity and quality. A certificate of authenticity from a recognized gemological laboratory can provide assurance that the gemstone is genuine.
In conclusion, obtaining crown gems is a process that involves mining, cutting, and polishing. The journey from a rough gemstone to a sparkling piece of jewelry is a testament to the beauty and rarity of these precious stones. Whether you are a collector or simply appreciate the allure of crown gems, understanding how they are obtained can enhance your appreciation for these extraordinary jewels.
