This 12 months’s Budget shines particular consideration on laboratory-grown diamonds, or LGDs. Finance Minister Nirmala Sitharaman stated the sector has excessive employment potential. A lot of schemes to advertise their analysis and improvement in India have been introduced.
What are laboratory-grown diamonds?
LGDs are manufactured in laboratories, versus naturally-occurring diamonds. But the chemical composition and different bodily and optical properties of the 2 are the identical. LGDs are manufactured in laboratories, versus naturally-occurring diamonds.
But the chemical composition and different bodily and optical properties of the 2 are the identical. LGDs are principally manufactured via two processes –
1. High stress, excessive temperature (HPHT) technique
2. or Chemical Vapour Deposition (CVD) technique
Both these strategies of rising diamonds artificially start with a seed, which is a slice of one other diamond. In the HPHT technique, the seed, together with pure graphite carbon, is uncovered to temperatures round 1,500 levels Celsius and intensely excessive stress.
In the CVD technique, the seed is heated to round 800 levels Celsius inside a sealed chamber full of a carbon-rich fuel. The fuel sticks to the seed, steadily constructing the diamond.
