Lab Grown Diamonds vs. Mined Diamonds

Lab Grown Diamonds vs. Mined Diamonds

When it comes to selecting a diamond, you may think about ‘Lab grown diamonds vs. mined diamonds - who wins?’ With technical progressions and increasingly conscious consumers, both options have clear strengths and drawbacks.

SkyGem & Co. helps you examine proven facts on ‘Lab grown diamonds vs. mined diamonds - who wins?’ We shall help you decide which one to choose from a professional perspective.

What are Mined Diamonds?

Mined diamonds are natural gemstones. They are formed deep within the earth over billions of years. Under immense heat and pressure hundreds of kilometres below the surface, carbon atoms crystallise into diamond structures. Afterwards, these diamonds are brought to the surface through volcanic activity. They are extracted via mining, then cut and polished.

Natural diamonds are finite and rare. They carry a sense of geological heritage and exclusivity.

What are Lab-Grown Diamonds?

Lab-grown diamonds, like a red diamond, are manufactured in controlled laboratory environments using advanced methods, such as:

  • High Pressure High Temperature (HPHT)

  • Chemical Vapour Deposition (CVD)

The process replicates the conditions under which natural diamonds form. But, it happens in weeks instead of billions of years. These diamonds share the same:

  • Crystal structure

  • Chemical composition

  • Hardness

  • Optical characteristics

Lab Grown Diamonds vs. Mined Diamonds – Who Wins?

Features

Lab-Grown Diamonds

Mined Diamonds

Price / Affordability

Significantly less expensive — often 70%–90% cheaper than equivalent quality mined stones.

Much costlier due to rarity, mining and supply-chain costs.

Quality & Appearance

Chemically and visually identical; often more consistent quality, with fewer inclusions due to controlled growth.

Unique imperfections can give character - but quality varies depending on natural formation and cutting.

Ethics & Environment

Much lower environmental impact - no mining, minimal land disruption, conflict-free origin, reduced water usage and emissions.

Mining can involve land disruption, habitat damage, potential ethical issues around labour and sourcing.

Resale & Long-Term Value

Generally poor resale value - limited secondary market and oversupply may drive prices down.

Historically stronger resale and investment value due to limited supply and established demand.

Emotional / Symbolic Value

Appeals to modern, value-conscious, ethically minded buyers looking for affordability and sustainability.

Carries traditional luxury prestige, rarity, and the appeal of owning a natural gem formed over Earth’s history.

The Bottom Line

There is no single ‘winner’ in the lab-grown diamonds vs. mined diamonds debate. The best choice depends on what you value. If affordability, ethical sourcing, environmental sustainability, and consistent quality are priorities, artificial diamonds, like a blue diamond, shine. On the other hand, if you cherish rarity, tradition, long-term value retention, and the emotional weight of a natural gemstone, mined diamonds remain the gold standard.
