Lab-grown and natural diamonds differ in cost, value retention, and market trends. Here’s what you need to know:
- Natural Diamonds: Formed over billions of years, cost more upfront (around $4,200 for 1 carat), and retain 20–60% of their value. They are rare and often seen as investments or heirlooms.
- Lab-Grown Diamonds: Created in weeks, cost significantly less (around $1,000 for 1 carat), but retain only 10–30% of their value. Prices are dropping due to advancing technology and market saturation.
Quick Comparison
| Aspect | Natural Diamonds | Lab-Grown Diamonds |
|---|---|---|
| Formation Time | Billions of years | A few weeks |
| Initial Cost (1 Carat) | $4,200 | $1,000 |
| Value Retention | 20–60% | 10–30% |
| Price Trend | Stable | Declining |
| Market Share (2024) | 80% | 20% |
| Investment Potential | Moderate to High | Limited |
Bottom Line: Choose natural diamonds for rarity and long-term value. Opt for lab-grown diamonds if upfront affordability and size matter more.
Natural Diamond Value Over Time
Natural Diamond Price History
Natural diamonds have shown steady performance through various economic shifts. Fancy colored diamonds, in particular, have experienced notable price increases. For instance, from 2003 to 2013, the price of a 0.50-carat Fancy Intense Pink diamond jumped from $30,500 to $145,000 per carat. Similarly, a 2.00-carat Fancy Intense Yellow diamond with VS+ clarity rose from $5,000 to $13,500 per carat . These price trends underscore the enduring appeal of natural diamonds as an investment.
What Affects Natural Diamond Value
The value of natural diamonds is shaped by several key factors:
| Factor | Influence on Value |
|---|---|
| Rarity | The total annual recovery of natural diamonds 1 carat and larger could fit inside one exercise ball . |
| Quality | Key attributes like cut, color, clarity, and carat weight determine the baseline value . |
| Market Demand | Driven by economic conditions and shifting consumer preferences . |
| Certification | Professional grading impacts both price and marketability . |
Global events also play a role. For example, while the 2008 financial crisis caused an initial dip in diamond prices, they quickly recovered . More recently, early 2024 saw price pressures due to reduced demand from China and increased competition from lab-grown diamonds . These dynamics not only affect current prices but also influence resale potential.
Natural Diamond Resale Facts
The resale market reflects the lasting appeal of natural diamonds. While diamonds have generally appreciated over the decades , their resale value typically falls between 20% and 60% of the original retail price . This gap is often attributed to retail markups rather than the stone’s actual value.
Secondary markets such as auctions, jewelry stores, and private sales play a role in maintaining diamond value. High-quality diamonds, particularly those with exceptional clarity, color, and cut, tend to hold their value better over time . Larger stones, due to their scarcity, also show stronger performance in resale markets .
Lab-Grown Diamond Value Over Time
Lab-Grown Diamond Market Data
Lab-grown diamonds have gone from being a niche product to capturing about 20% of the total diamond market . Over the 12 months leading up to November 2024, sales of lab-grown diamond jewelry jumped by 51% .
Prices for lab-grown diamonds, however, show a steady downward trend across various carat weights:
| Carat Weight | Current Price | 1-Month Change |
|---|---|---|
| 1 Carat | $602 | -2.43% |
| 2 Carat | $1,282 | -4.83% |
| 3 Carat | $2,018 | -1.66% |
| 4 Carat | $2,476 | +1.68% |
Since 2015, the price gap between lab-grown and natural diamonds has widened significantly. Lab-grown diamonds, once priced at a 10% discount, can now cost up to 90% less than their natural counterparts . Morgan Stanley projects that the market share of lab-grown diamonds, which stood at 14.3% of the total diamond supply last year, will increase to 18% this year and 21.3% next year . This growing market share is putting pressure on prices, as detailed in the next section.
What Affects Lab-Grown Diamond Prices
Several factors are driving the ongoing decline in lab-grown diamond prices:
| Factor | Impact |
|---|---|
| Production Technology | Advances in technology have lowered manufacturing costs. |
| Market Competition | More suppliers entering the market are pushing prices down. |
| Retail Competition | Increased competition among retailers is squeezing profit margins. |
Morgan Stanley highlights this trend, stating, "The trend of increasing lab-grown diamond market share remains unchallenged, adding to the structural challenges being encountered by the natural diamond market" .
Experts predict further price drops, with some analysts suggesting that lab-grown diamond prices could fall by another 50–80% . This shift reflects a move away from a high-value, low-volume approach to one based on higher volumes and lower prices .
Lab-Grown Diamond Resale Facts
Resale remains a weak point for lab-grown diamonds. These diamonds typically retain only 10–30% of their original retail price, compared to the 20–60% retained by natural diamonds .
A growing trend has emerged where couples are swapping out their lab-grown diamonds for smaller natural ones. Cormac Kinney, CEO of Diamond Standard, notes, "Jewelers tell me that a growing number of couples are coming one to three years into a marriage and replacing a synthetic stone with a smaller but real natural diamond" .
Future resale values are likely to face even more pressure due to increased production, lower manufacturing costs, and market saturation.

Since 2017, lab-grown diamond prices have dropped dramatically, with some now selling for up to 90% less than their natural counterparts. The gap between the two continues to grow. In the U.S., nearly half of all engagement ring stones sold in 2023 were lab-grown, a significant jump from just 12% in 2019 . However, the choice between lab-grown and natural diamonds often goes beyond numbers, influenced by personal and social considerations.
Personal and Social Factors
Emotional and ethical considerations play a big role in diamond selection, often outweighing financial factors.
Generational preferences are a key driver. Around 80% of millennials and Gen Z prefer lab-grown diamonds, while baby boomers tend to favor natural ones . Awareness of lab-grown diamonds has surged, with 70% of consumers now familiar with them. Among these, 65% believe lab-grown diamonds offer better value for money than natural diamonds .
Natural diamonds, however, hold their ground due to:
- Rarity and Uniqueness: Each natural diamond is one of a kind, formed over millions of years.
- Historical Significance: They have long symbolized love and commitment.
- Legacy Value: Often seen as heirlooms, they are more likely to be passed down through generations.
"Fashion jewelry is always worth a small fraction of real jewelry. Only real is rare."
- Cormac Kinney, CEO of Diamond Standard
The way people buy diamonds is also changing. In 2023, 60% of lab-grown diamond purchases were made online, compared to 45% for natural diamonds . Ryan Atlas, Senior Director at Brilliant Earth, explains: "The rise in popularity of lab-grown diamonds is part of a larger trend of a higher demand for transparency from the jewelry industry" . This shift highlights how personal values and ethics now play a major role in diamond purchases.
