Lab Diamonds vs. Earth-Mined Gems

How Do Diamonds Form Under the Earth’s Surface? Lab Diamonds vs. Earth-Mined Gems

For a long time, mined diamonds from deep in the earth have dazzled us with their beauty and allure. But now lab-grown diamonds offer an ethical alternative that is less damaging to the environment. Lab diamonds are designed to look exactly like mined ones but are made above ground using technology that mimics natural conditions. They have many of the same qualities as mined diamonds but cost less and are more eco-friendly to produce. As people care more about sustainability and ethics, lab-grown diamonds are becoming more popular.

This article explores how natural diamonds form, how they are mined, and how lab diamonds are made. It also compares lab and mined diamonds so you can make an informed choice. The future of diamond jewelry includes both timeless natural beauty and innovative lab-grown sparkle.

How Do Diamonds Form Under the Earth's Surface?

Natural diamonds start extremely deep under the ground, over 90 miles (approximately 150-200 kilometers)into the Earth's mantle layer. The mantle is made of very hot, thick rock. Down there, the pressure from the rock above is tremendous, almost 1 million times the pressure we feel on the surface!

At these intense depths, the massive pressure squishes carbon atoms from decomposed organic matter together. The hot temperature, which can reach over 2,000 degrees Fahrenheit, provides the heat needed for the carbon atoms to fuse. Under these extreme conditions, the carbon crystallizes into rough diamonds over billions of years.

These newly formed diamond crystals remain buried in the mantle where they were born. They only make it close to the Earth's surface when volcanic eruptions happen. When volcanic pipes form and lava rises up, it can carry diamonds trapped in the rock upwards. This journey from deep mantle to near-surface takes an incredibly long time - over 3 billion years!

This complex natural process under intense heat and pressure makes diamonds rare and special. Their rarity and uniqueness are part of what makes mined diamonds so prized.

How Mined Diamonds Are Extracted

Diamonds form deep inside the Earth over billions of years. To extract these rare gems, miners employ different techniques based on the location of diamond deposits.

Open-Pit Mining

With open-pit mining, huge open holes are dug in the earth to reach diamond deposits. Massive trucks and shovels are used to make pits that can be deeper than the height of the Statue of Liberty! This heavily damages the land surface.

Underground Mining

Tunnels are dug deep below the ground to access diamonds. This can make the land above unstable, causing sinkholes and soil erosion. Explosives are often needed to blast through rock.

Alluvial Mining

In river mining, gravel, and sand in riverbeds containing diamonds are scooped up with buckets and sieves. This can harm local water flows, fish, and plants.

Marine Mining

Offshore diamond mining uses ships with giant vacuum-like hoses to suck up seafloor sediment. This damages ocean habitats and disrupts ecosystems.

Community Impacts

While mining provides income, workers may receive low wages and work in hazardous conditions. Pollution can cause health problems. Conflict diamonds fuel violence and human rights abuses. Overall, mining can negatively impact local communities and environments.

Lab-Grown Diamonds: Modern Technology Creates Dazzling Gems

Scientists have developed special techniques to produce real diamonds above ground in controlled lab environments. This technology recreates the extreme heat and pressure found deep inside the Earth that transforms carbon into diamonds.

High-Pressure High Temp (HPHT) Method

One method is called High Pressure High Temperature (HPHT). A small carbon starting material is placed into a chamber or press. The press squeezes the carbon at pressures over 1 million times the air pressure we feel. Heat over 2,500°F is applied. This high pressure and heat turn the carbon into diamond crystals.

Chemical Vapor Deposition (CVD)

Another method is Chemical Vapor Deposition (CVD). A chamber contains hydrogen gas and carbon atoms. The carbon atoms are deposited onto a diamond seed plate. As the atoms build up, they crystallize into diamonds.

Both methods allow scientists to carefully control the lab conditions. This optimizes the diamond production process far above ground. Lab diamonds can form in just a few weeks or months compared to natural diamonds taking billions of years! The controlled lab environment produces identical sparkling diamonds much more efficiently.

Why Lab Diamonds Are Better

Lab-made diamonds have many benefits over natural mined diamonds. Here are the top reasons lab diamonds are a better choice.

Good for the Planet

Mining diamonds harms the environment. Labs make diamonds without digging big holes and scarring the land. Labs use less energy and make less pollution. Mining causes waste and damages habitats. Overall, lab diamonds are much greener and more eco-friendly.

Save Money

Natural diamonds take many years to grow deep underground. Lab diamonds grow much faster above ground. Making diamonds in labs takes just weeks or months, not billions of years. This speeds up production. Faster production means lab diamonds cost a lot less to buy. Mined diamonds are more expensive.

Same Sparkle

Lab diamonds and mined diamonds look exactly the same. Both shine bright with equal beauty. Lab diamonds are just as hard, clear, and fiery. They pass diamond quality tests. You get the dazzling brilliance for less cost.

More Custom Choices

Labs can grow diamonds in more shapes, colors, and sizes than nature can make. More custom cuts and colors to match your personal style. Design your perfect diamond for your jewelry.

Ethical and Safe

Lab diamond production follows high ethics and safety standards for workers and the environment. No unfair worker treatment or pollution like mining can have. You can feel good about lab diamonds as a responsible choice.

Supply Reliability

Lab production steadily generates enough high-quality diamonds year-round. More consistent supply versus fluctuating natural diamond mining output. Labs can meet demand better and avoid shortages.

As you can see, lab-created diamonds are an ethical and affordable alternative with many advantages. Choosing lab diamonds is a smart decision that sparkles. More advantages, check this blog: Why Choose Lab-Grown Diamonds?

Lab-grown diamonds and mined diamonds have important similarities and differences. Here is how the two stack up.

4Cs: Lab Diamonds vs. Natural Diamonds

  • Cut: The cut refers to the facets and proportions that optimize sparkle. Both lab and natural diamonds can be expertly cut for maximum brilliance and fire. Common shapes like round, princess, cushion, emerald, and oval cuts are available for either.
  • Color: Diamonds can be colorless or have pale yellow, brown, pink, blue, or other tints. Lab diamonds can be grown in almost any color, including rare bright hues. Natural diamond colors are more limited based on mineral impurities affecting the stone as it forms. Both provide colorless and pale-tinted diamonds.
  • Clarity:This describes the clarity grade based on internal flaws called inclusions and external marks called blemishes. Labs have more control during growth to minimize flaws, so lab diamonds often rate higher clarity grades with fewer defects.
  • Carat:The diamond's weight is measured in carats. Mined diamonds have a limited supply of large stones over 1 carat. Lab diamonds can be grown to customize specific carat sizes over 1 carat. The size availability is similar between 0.25 to 1 carat ranges.
