1. The start of imitation of gems 

The idea of imitation of natural gemstones started in Egyptian civilization. The people in this civilization used to copy precious gems using colored glasses. This practice of Synthetic gemstone production continued until the end of the 19th century and most of the famous sacred gems, such as Turquoise were replicated.

1. The middle age 

The Middle Ages marked the evolution and improvement in technology. This played an important role in lab-created gemstones. This age marked the synthesis of a replica of natural gemstones. 

1. Chemical advancements 

people later realized that synthetic and natural gemstones share the same elements and characteristics, and chemical advancements allowed people to manufacture more synthetic gemstones. 

1. The Auguste Verneuil method

Auguste Verneuil led the manufacture of synthetic gemstones using a famous technique known as the flame fusion method. This method involved mixing aluminum oxide powder and a trace of chromium. This mixture was then crystallized and formed into a rough form of synthetic corundum.

1. Expansion and refinement of processes 

After the success of very renewal process, the process of creating synthetic gemstones fastened. other processes are also developed to create different types of gemstones such as:- 

• Hydrothermal synthesis

This process was developed in the 1950s. This method included replicating natural gemstone formation by dissolving the mineral in a high -pressure high-temperature water solution.

• Czochralski process

This process was introduced in the early 20th century and it was refined from time to time. It involved pulling a seed crystal from a metal of desired gemstone and it was used to create bigger high-quality crystals.

1. The movement further 

Multiple processes started to develop with the advancement in technology. Processes such as HPHT(High-pressure high temperature)  and CVD(Chemical vapor deposition)  started which helped to create synthetic gemstones with much precision and with varied luster and qualities. 

Methods of Lab-Creating Gemstones

Check out some of the leading methods of creating lab gemstones that are widely used today. 

1. Flux melt method 

This process involves mixing raw material with a flux. This mixing helps to reduce the melting point of the raw material. It helps to increase the melting process under high pressure. This helps subsequently crystalize into gemstones 

1. Flame fusion method 

This process involves liquefying raw material powder into intense flames. These flames are then cooled and crystallized to form gemstones 

1. High-pressure high-temperature method(HPHT)

This process replicates the original formation method of the gemstone. The synthetic gemstone is made to undergo heat and pressure in a sealed vessel. In this way, it is given the condition of a natural gemstone. 

1. Chemical Vapor deposition 

This process involves depositing the raw material alongside a blend of gases. The vapor generated through heating is introduced into a substrate that eventually matures into a crystalline gemstone.

Technological Advances in Gemstone Creation

The technology is seeing a rapid growth and advancement. Lab-grown diamonds are seeing a surge in demand and the technology is making sure that it meets the demands. Technological advances in gemstones are at their peak. Check out some of the processes that have evolved:-

1. Microwave plasma chemical vapor deposition (MPCVD) 

This method is a variant of the CVD method. It uses microwaves to produce plasma that contains carbon. The crystals of raw material are grown by the use of plasma. This method is perfect for growing synthetic gemstones at a faster rate and with much precision. 

1. Ultrasonic cavitation-based method

This method is used to create high-quality diamonds that are smaller in size. A piece of raw material is placed in a liquid that contains carbon and a subject to ultrasonic waves. These waves then make small bubbles that produce high pressure and high temperature. Due to this high pressure and high temperature, the carbon transforms into a diamond.

1. Laser backed method 

The laser method is an efficient method that uses a laser to create gemstones of high quality. Laser can be controlled precisely and it helps to manufacture precise gemstones in a cheap and sustainable way.

Environmental and Ethical Considerations 

Lab-created gemstones are far better than natural gemstones, considering the environmental aspect. Some of the environmental and ethical benefits that it offers are:- 

1. No mining 

creating gemstones in a laboratory under a controlled environment does not involve mining the earth’s crust which causes severe environmental disruption. This makes lab-created gemstones a more sustainable choice.

2. Ethical assurance 

Lab-created gemstones, reduce the need for unethical mining practices, and the uncertain risk of sourcing from conflicted zones. It ensures transparency in the process.

With its environmental and ethical benefits, it also has a flip side that shows some of the concerns. Check out the below-mentioned concerns that come with lab-created gemstones.

1.  Energy consumption 

The controlled environment of laboratories requires a high energy to produce gemstones. It adds burden on the sources of energy that already exist. 

• Harmful chemicals 

Processes such as CBD use chemicals to curate gemstones. This chemical may be harmful and cause negative environmental impacts if not handled properly. 

•  Disturbing the livelihood

Lab-created gemstones have brought a disruption in the industry. The population that used to depend on natural gemstones has had a severe impact on their lives.

All the concerns mentioned above can be controlled to make lab-created gemstones a perfect fit for sustainability and fashion.
