As lab-grown diamonds reshape the jewelry market, this article explores whether they can truly rival the enduring allure of natural diamonds, comparing their origins, production, and cultural significance.
In recent years, lab-grown diamonds have emerged rapidly in the jewelry industry. The question now is whether these diamonds can replace natural diamonds, or will the “King of Gems” crown still remain with natural diamonds? Natural diamonds are formed over millions of years under pressure and temperature within the Earth’s layers, while lab-made diamonds can be created in just a few weeks using scientific technology. Their production primarily occurs through two methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These two technologies have made lab-grown diamonds as refined and beautiful as natural ones.
In terms of quality, there is almost parity between the two. At the physical, chemical, and optical levels, it is difficult to distinguish between the two types of diamonds. International agencies like GIA and IGI are also certifying lab-grown diamonds. Despite this, the rarity and emotional value of natural diamonds are the aspects that still make them special.
From a price perspective, lab-grown diamonds are 60 to 70 percent cheaper. Due to environmentally friendly technology, they are not only considered an ethical choice but also a step towards sustainable consumption. Indian cities like Surat are becoming global hubs for both the production and polishing of lab diamonds, providing the country with new employment and export opportunities.
The situation is slightly different from an investment viewpoint. Natural diamonds are considered a safe investment due to their limited availability and enduring value, while the price of lab-grown diamonds may decrease due to technological reasons. This is why investors still prefer natural diamonds.
Industry experts estimate that the demand for lab-grown diamonds could double in the coming five years, but the allure of natural diamonds will not completely diminish. Both will remain in their respective markets: lab-grown diamonds as a modern and affordable option, and natural diamonds as a traditional, valuable, and investment-worthy symbol.
In India in 2025, the price of natural diamonds is approximately between ₹70,000 to ₹10,00,000 per carat, depending on the diamond’s quality (cut, color, clarity) and certification. High-quality natural diamonds sell for ₹4,00,000 to ₹10,00,000 per carat, while medium-quality diamonds are available in the range of ₹1,50,000 to ₹4,00,000 per carat. Smaller diamonds start from ₹40,000, but prices can vary significantly based on quality.
In comparison, lab-grown diamond prices are much lower and are available in the range of ₹30,000 to ₹80,000 per carat, providing a more affordable option in the Indian market. Globally as well, lab-grown diamonds are becoming popular as a cheaper and environmentally friendly option, while natural diamonds remain expensive and desirable due to their rarity and investment value.
