by Suzanne Sachs — 5 min read
THE BASICS --
Lab-grown diamonds are often promoted as a more environmentally-friendly option than naturally mined stones, but the environmental impact of lab-grown diamonds is not as straightforward as it seems. A better understanding of lab-grown diamonds can help you recognize what is entailed in creating a diamond in a laboratory, so you can make the best decision you feel most comfortable with purchasing diamonds for an engagement ring, wedding ring, wedding band, or any other jewelry. In this guide, we’ll explore the environmental and ethical considerations of choosing between lab-grown, mined, and vintage diamonds, helping you make an informed decision that aligns with your values.

Why Natural Diamonds Are Labeled as "Bad" for the Environment
It is no secret or surprise that diamond and gemstone mining can be a very destructive process. Different types of mines can destroy habitat, create both air and water pollution, and produce tremendous amounts of greenhouse gasses. Explosives used in mining operations can be hazardous not only to workers but to surrounding communities, and the road construction to reach mining sites as well as to ship out the mined stones causes even more environmental and habitat damage. Rivers may be diverted or blocked to access alluvial deposits for mining, and chemicals used to facilitate mining may cause toxic contamination that may take years to clean up, if it is even cleaned up at all.
Regulations governing mining operations vary in different parts of the world, and in some areas where diamond mining is very lucrative, there may be few, if any, regulations. Furthermore, many companies take no steps to restore local ecosystems or habitats once a mine is no longer productive, but instead move on to their next operation without regard for what they may leave behind.
It takes approximately 250 tons of mined earth to produce just one carat of diamond, and the damage that mine may create can last for many years longer than even the most romantic proposal, most glamorous wedding, or happiest of anniversaries.
Lab-Grown Diamonds Aren’t That Much "Better"
Because naturally mined stones are associated with so much environmental damage, lab-grown diamonds are often touted as eco-friendly. It is true that the resources necessary to produce a laboratory gem are often less than the damage from natural mining operation, but the comparison is relative — lab-grown diamonds still require tremendous resources and can be responsible for significant environmental destruction.
The Environmental Impact of Lab-Grown Diamonds
• Energy Consumption
Lab-grown diamonds require substantial energy, often sourced from fossil fuels, contributing to significant carbon emissions.
• Water Usage
The production process demands large amounts of water for cooling and operations, further straining natural resources.
• Facility Construction
Building the specialized facilities for lab-grown diamond production leads to habitat destruction and additional environmental costs.
• Global Shipping
The limited number of production facilities means lab-grown diamonds must be shipped worldwide, adding to their carbon footprint.
Environmental Costs: Lab-Grown Diamonds vs. Vintage Diamonds
The table below compares the environmental impact of lab-grown diamonds versus vintage diamonds across several key categories, including carbon footprint, energy consumption, water usage, waste production, and land disruption. By highlighting these differences, the table provides valuable insights into the sustainability of each option, helping consumers make more informed decisions when choosing between modern lab-grown diamonds and their vintage counterparts.
| Environmental Impact Category | Lab-Grown Diamonds | Vintage Diamonds |
|---|
| Carbon Footprint | 3 (Moderate Impact) | 1 (Low Impact) |
| Energy Consumption | 4 (High Impact) | 2 (Low Impact) |
| Water Usage | 4 (High Impact) | 1 (Low Impact) |
| Waste Production | 2 (Moderate Impact) | 1 (Low Impact) |
| Land Disruption | 1 (Low Impact) | 1 (Low Impact) |
Resale Value
Furthermore, lab-grown diamonds have very little resale value, and as new gems are continuously manufactured to meet demand, their prices are plummeting. This is completely contrary to the much higher resale value for natural vintage diamonds, which can be handed down in heirloom jewelry or reset into different pieces to create “new” jewelry with old, natural stones.
“I've purchased two vintage rings from Suzanne over the past decade and my wife has loved both. Great service, communication and speedy delivery.”
Comparing the Environmental Impact of Different Types of Diamonds
Ultimately, both naturally mined and lab-grown diamonds can be tremendously environmentally damaging. While lab-grown gems may seem somewhat more eco-friendly, the lack of resale interest negates that slim margin of environmental friendliness.
Vintage vs. Lab Grown vs. Mine: Which Is Truly the Most Sustainable Choice?
• Vintage and Antique Diamonds
The most eco-friendly stones of all are antique and vintage diamonds. While these stones were naturally mined many years before lab-growing techniques even existed, the mining techniques decades ago produced fewer greenhouse gasses (due to less heavy equipment), and reusing the stones today creates no new environmental damage. These stones are the ultimate in recycling and reusing, particularly if the entire ring or other vintage jewelry piece is preserved and thus there is no new metal needed either.
• Lab Grown Diamonds
Lab-grown diamonds are often marketed as an eco-friendly alternative to mined diamonds. While they avoid the destructive mining process, they still require significant energy and resources for production, leading to a substantial carbon footprint. Additionally, their limited resale value means that new diamonds must be continually produced to meet demand, which can contribute to further environmental impact.
• Mined Diamonds
Mined diamonds, particularly those from operations with poor environmental regulations, are often associated with significant ecological damage, including habitat destruction, water pollution, and high carbon emissions from mining activities. The extensive environmental costs associated with extracting just one carat of diamond highlight the unsustainable nature of traditional mining practices.
