Shopping for the perfect engagement ring can be a daunting task. You have to decide on the cut – whether to buy emerald, pear, cushion, round, or marquise. Likewise, you have to select the size, weight, and whatnot. And now, thanks to the advanced technology, you have another factor added to the already never-ending list – whether to buy lab-grown diamonds or mined ones.

Lab-grown diamonds vs. mined is one of the most sensitive topics a diamond-shoppers can encounter. In the past few years, there has been a lot of buzz about lab diamonds, both positive and negative. This has made people skeptical about whether lab-grown diamonds are worth buying or not.

The market share of lab-grown diamonds in the overall diamond market has steadily increased in recent years. It is expected to reach ten percent of the global diamond market by 2030. Studies show that the industrial diamond market in the US will be worth $238.1 billion in 2025. Lab-grown industrial diamonds are estimated to account for $200 million of that total. Considering this and the fact that only half of the US population was aware of cultured diamonds in 2018, people need to learn about the various cost-effective alternatives to natural diamonds.

Since the shape and size of your diamond depend upon your personal preference and budget, you are alone in the decision. However, we can help you decide whether to go for lab-grown or natural diamonds. This post will discuss the differences between mined and lab-grown diamonds to help you decide which one to purchase. So, let’s get started!

Lab-Grown Diamonds vs Mined Diamonds

A surprising fact about lab diamonds is that they look exactly like natural diamonds. The only possibility that someone can tell them apart just by looking at them is if they are born and raised in a mine – so, yeah, the chances are pretty less.

This leaves us with a few factors that make lab-grown diamonds different from mined ones. Here are some points of differences between cultured and natural diamonds:

1- Manufacturing Process

Natural diamonds are forged deep inside the Earth’s surface in the mantle layer. Carbon reconfigures itself on an atomic level over billions of years of high heat and pressure, resulting in the solid-state diamond. Volcanic eruptions bring them closer to the Earth’s surface from where these precious stones are mined.

On the other hand, a lab-manufactured diamond copies the exact manufacturing procedure of a natural diamond. It has the same chemical, physical, and visual properties as a natural stone, except it is generated in a machine rather than on the Earth. CVD (chemical vapor deposition) and HPHT (high-pressure, high-temperature) are the two technologies used to make lab diamonds. Both procedures produce high-quality, genuine diamonds similar to those obtained from nature.

HPHT Process

HPHT diamonds are created in a laboratory by simulating the high-pressure, high-temperature settings that occur naturally in the formation of diamonds. This method yields a lab-grown diamond crystal with an irregular shape.

CVD Process

The CVD process entails splitting the molecules of a carbon-rich gas, such as methane, into carbon and hydrogen atoms. These are then coated on diamond seeds to form a square-shaped diamond crystal. After the development process, most CVD-grown diamonds require extra treatments such as heat or irradiation to intensify or change their hues.

CVD is the most popular method; diamonds manufactured under this process are expected to reach $16.5 billion by 2024. Diamonds manufactured under the HPHT process have a lower economic value as they often turn brown or yellow.

2- Price

The price of a diamond, either natural or synthetic, is determined by several factors, including:


If you think the beauty and feel make diamond such a pricey metal, you, my friend, are mistaken! Their rarity is the major reason why natural diamonds are so expensive! “Natural diamonds get their worth as a natural, billion-year-old valuable jewel and have proved over decades to rise in value as they become more uncommon,” according to the Natural Diamond Council.

But do synthetic diamonds compete with mined ones in their prices? Lab diamonds were 23 to 25% more expensive than natural diamonds in 2017 when the synthetic diamond manufacturing industry was just booming. By 2020, these price differences had significantly lessened. The retail price of lab-grown diamonds is roughly 35% of natural diamonds’ selling price.

Carat Weight

Apart from their scarcity, the degree of the price difference between natural and synthetic diamonds is also determined by their weight. Larger carat lab-grown diamond prices are also falling faster than smaller carat weights.

Prices for synthetic diamonds between 3 and 3.99 carats fell 10.6% in 2021, while prices for those over 4 carats have fallen 8.7%.


Lab-created diamonds are available in a variety of aesthetic colours. These are produced by deliberately introducing elements such as nitrogen and boron into the manufacturing process. However, natural exotic coloured diamonds are significantly more expensive per carat than lab-grown coloured diamonds.

Natural coloured diamonds, like blue and pink, are highly rare and sell for thousands of dollars per carat. However, if you buy lab-grown diamonds in the same shades, you will be able to save a considerable amount of money.

3- Value

Lab-grown diamonds, like mined diamonds, are valued based on the 4Cs: colour, cut, clarity, and carat weight. When you buy something, you lose a significant portion of its worth the instant you buy it. The reselling value for synthetic diamonds is far less than for natural diamonds.

Natural diamonds maintain roughly 50% of their initial value. On the other hand, Lab-grown diamonds have little to no market value. This means that you won’t be able to recover any of your investment if you resale a synthetic diamond.

4- Durability

Synthetic diamonds are manufactured from the same carbon material that natural diamonds are made up of. Despite being manufactured in a controlled environment by men, laboratory-grown diamonds are still the hardest substance on the planet. They have a MOHS hardness of ten, making them impossible to chip, break, shatter or scratch as genuine diamonds.

5- Sustainability

Some diamond shoppers are concerned about the environmental consequences of natural diamond mining. Buying mined diamonds is a lawful act. However, it is reasonable to believe that man-made diamonds are more long-term sustainable than those mined from the soil.

The lab-grown diamond industry provides customers with a more environmentally friendly diamond choice. When comparing two comparable diamonds, mined vs cultured, it’s critical to convince clients that cultured offers a viable option that requires far less land, produces far fewer emissions, uses far less water, and does not threaten human lives. In 2018, the Federal Trade Commission (FTC) recognized cultured diamonds as real and stated they have a lower carbon footprint than mined diamonds if generated under ideal conditions.

6- Color

A high-quality lab-grown diamond will be classified on the same level as a genuine diamond when it comes to colour. Because there is no visible difference between a lab-grown and a natural diamond, most people look for stones graded between G and J, which are near-colourless in both forms. True colourless diamonds, graded D through F, are extremely rare and valuable.

A lab diamond will almost always have the same brightness and shine as a real diamond, so they are a cost-effective option without sacrificing quality.

7- Clarity

The Gemological Institute of America grades lab-created diamonds using the same processes and standards of natural diamonds. Because lab-grown diamonds are grown rather than cut, they will pick up imperfections or “flaws” that impact the brightness and purity of the stone. (The more inclusions a stone has, the cloudier it becomes and the lower its clarity rating.) Clarity ratings for lab-grown diamonds range from Flawless (F1) to Included (I2), just like real diamonds (I3).

However, the terminology GIA uses to describe the colour and purity of laboratory-grown diamonds differs from those used to describe natural diamonds. They use broader classification terms (Colorless, Near-Colorless, Faint, Very Light, and Light) instead of D-to-Z colour grades. The clarity grades for cultured diamonds are also replaced with descriptive categories (Very Slightly Included, Slightly Included, etc.) compared to the abbreviations for mined diamonds (VVSI, SI2, etc.).

Pros and Cons of Buying Lab-Grown Diamonds

Synthetic diamonds have certain flaws, but they are less than their pros. If you are still confused about whether to buy lab-grown diamonds or not, take a look at this chart to make an informed decision:


Less Expensive than Natural Diamonds

Lab-grown diamonds cost significantly less than natural diamonds for the same weight. So, you will get a larger cultured diamond for the same amount.

Identical Appearance

They look the same and are also chemically identical. It’s only that they are grown through a different method.


Even though lab-grown diamonds require considerable energy to manufacture, they are more environmentally friendly and sustainable compared to mined diamonds.

Diverse Options

You can get a lab-grown diamond customized for your favorite color. You will get them cheaper than natural diamonds, which are only available in several shades and cost a fortune.


Uncertain Resale Value

If the resale value is one of your primary considerations, lab-grown diamonds aren’t the best option. Since synthetic diamonds have only been around for a few years, they haven’t established a worth comparable to natural diamonds. So, you are not guaranteed a specific resale value at purchase.
