Natural vs. Lab-Grown Diamonds

About Lab Grown Diamond

At Tvisa Diamonds, we celebrate the brilliance of innovation with our exquisite collection of lab grown diamonds—where timeless elegance meets modern responsibility.

Lab grown diamonds are real diamonds, created using advanced technology that replicates the natural diamond-growing process. They have the same physical, chemical, and optical properties as mined diamonds—so much so, that even professional gemologists need specialized equipment to tell them apart.

🌿 Ethical. Beautiful. Sustainable.

Our lab grown diamonds offer a more sustainable and eco-conscious alternative to traditional mining, without compromising on sparkle or quality. They’re crafted in controlled environments using two key methods:

Chemical Vapor Deposition (CVD): Carbon-rich gas is used to grow diamond crystals layer by layer.

High Pressure High Temperature (HPHT): Mimics the natural conditions under which diamonds form in the Earth’s mantle.

Both methods result in stunning diamonds that are conflict-free, environmentally friendly, and more affordable than their mined counterparts.

💎 Why Choose Lab Grown Diamonds?

• 100% Real Diamonds – Certified and graded by the same standards as natural diamonds

• Conflict-Free & Ethical – Peace of mind with every purchase

• Eco-Friendly – Lower environmental impact compared to traditional mining

• Exceptional Value – Get a larger, higher-quality diamond for the same price

Natural Diamonds

Lab-Grown Diamonds

✨ Formation Process

Natural Diamonds are formed over billions of years deep within the Earth’s mantle under extreme pressure and temperature. They are created through a natural geological process, which makes them rare and unique.

Lab-grown diamonds are created in a laboratory using one of two methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). These methods mimic the natural conditions that occur deep inside the Earth but in a much shorter timeframe (a few weeks to months)

🧬 Chemical and Physical Properties

Made of pure carbon atoms arranged in a crystal lattice, natural diamonds have unique inclusions (internal imperfections) that can be used to distinguish them from lab-grown diamonds.

Lab-grown diamonds are also composed of pure carbon atoms arranged in the same crystal lattice, making them indistinguishable from natural diamonds to the naked eye or through most testing methods. They are chemically, physically, and optically identical to natural diamond

💰 Price

Natural diamonds require intensive mining, logistics, land use, labour, and environmental restoration — all of which add major cost.

Lab diamonds does not require mining, land use etc, making them more efficient and eco-friendly to produce, hence have price 45-60% less than Natural Diamonds.

🧭 Rarity and Availability

Takes millions of years to form, making them very rare

They can be produced on demand, making them more readily available

🌍 Environmental Concerns

The mining process for natural diamonds can have a significant environmental impact, including land disruption, water usage, and carbon emissions.

They are free from environmental concerns associated with diamond mining because they require fewer resources to produce and have a lower carbon footprint.

📜 Certification

Certified by recognized gemological laboratories such as the GIA (Gemological Institute of America) or IGI (International Gemological Institute). The certification process ensures the quality of the diamond, including its cut, colour, clarity, and carat weight

💎 4 Cs

Cuts : high-quality cuts possible
Clarity : they have inclusions due to natural formation
Carat : Limited by natural growth, larger diamonds are rare
Color : more likely to have yellow or brown tone

Cuts: Ideal cuts are easier to achieve.

Clarity: They have fewer inclusions, cleaner stones but can have small identifying inclusions
Carat : Easier to create larger stones, often more affordable in larger sizes
Color : Any colour is achievable
