What is the price of diamonds per carat today?

Current Market Prices

Diamonds have long been valued for their brilliance and rarity, making them a significant investment and a symbol of luxury. As of May 2024, the price of diamonds per carat varies widely depending on several key factors, including carat weight, cut, color, clarity, and overall quality. On average, the price range for a one-carat diamond can be anywhere from $2,500 to $20,000. This broad range reflects the nuances in grading and market demand.


For instance, diamonds of higher quality—those with superior cut, color (closer to colorless), and clarity (fewer inclusions)—command higher prices. A flawless, colorless one-carat diamond with an excellent cut can fetch prices at the upper end of the spectrum, or even higher in some cases, particularly if the diamond has been certified by reputable organizations like the Gemological Institute of America (GIA).


High-Quality Diamonds

At the top end, high-quality diamonds are typically priced between $15,000 and $20,000 per carat. These diamonds exhibit exceptional clarity, excellent cuts, and are nearly or completely colorless. High-end jewelers and specialty retailers often sell these diamonds, catering to discerning customers looking for the best available gems.

Mid-Range Diamonds

In the mid-range, prices for one-carat diamonds generally fall between $5,000 and $10,000. These diamonds may have minor inclusions or slight color tinges that are often invisible to the naked eye but detectable under magnification. This range is popular for engagement rings and other fine jewelry, balancing quality with cost.

Lower-Quality Diamonds

Lower-quality diamonds, while still valuable, are more affordable, with prices ranging from $2,500 to $5,000 per carat. These diamonds may have visible inclusions or more pronounced color variations. They offer a budget-friendly option for consumers who still want the allure of a diamond without the premium price.

Factors Affecting Price

The price of diamonds per carat is influenced by multiple factors, often summarized by the Four Cs: Carat, Cut, Color, and Clarity. Each of these characteristics plays a crucial role in determining a diamond’s market value.

Carat Weight

Carat weight is one of the most straightforward factors affecting a diamond’s price. Larger diamonds are rarer than smaller ones, so the price per carat increases exponentially with size. For example, while a one-carat diamond might cost $5,000, a two-carat diamond of similar quality could cost $20,000, reflecting not just the size but the rarity and demand for larger stones.


The cut of a diamond significantly impacts its brilliance and overall appearance. A well-cut diamond reflects light better, enhancing its sparkle and perceived beauty. Diamonds with excellent or very good cuts command higher prices than those with fair or poor cuts. The precision of the cut affects not only the stone’s visual appeal but also its value on the market.


Diamonds are graded on a color scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are the most desirable and expensive because they reflect the most light, exhibiting maximum brilliance. As the color grade moves towards Z, diamonds tend to decrease in value, with noticeable color tints impacting their desirability and price.


Clarity refers to the presence of internal or external imperfections, known as inclusions and blemishes, respectively. Diamonds with fewer and less noticeable inclusions are more valuable. The GIA clarity scale ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye). Higher clarity grades significantly enhance a diamond’s price per carat.


Certification by recognized gemological laboratories, such as the GIA, American Gem Society (AGS), or International Gemological Institute (IGI), also affects a diamond’s price. Certified diamonds often sell at a premium because the certification provides assurance of the diamond’s quality and characteristics, adding to buyer confidence and market value.

Comparison with Different Carat Weights

When comparing diamond prices, it’s essential to consider how carat weight influences the overall cost and price per carat. Here’s a closer look at how different carat weights affect pricing:

Half-Carat Diamonds

Half-carat diamonds are popular for their affordability and versatility in various jewelry settings. Prices typically range from $1,000 to $5,000, depending on quality. The price per carat for half-carat diamonds is often higher than that for one-carat stones because cutting smaller diamonds can be more challenging, and the demand for perfectly cut smaller diamonds remains high.

One-Carat Diamonds

As mentioned earlier, one-carat diamonds are a standard benchmark for pricing. With a broad range from $2,500 to $20,000, these diamonds cater to a wide array of buyers. They strike a balance between visibility and affordability, making them a popular choice for engagement rings.

Two-Carat Diamonds

Two-carat diamonds see a significant jump in price, reflecting their rarity. Prices for two-carat diamonds can range from $10,000 to $80,000 or more, with the price per carat often higher than for smaller stones. The increase is due to the rarity and desirability of larger diamonds, as well as the difficulty in finding stones of that size without significant flaws.

Three-Carat and Larger Diamonds

Diamonds that are three carats and larger are considered exceptionally rare and often command premium prices. The price per carat for these diamonds can exceed $30,000, especially for stones with excellent quality. These diamonds are typically used in high-end jewelry pieces and investment-grade collections.

Market Trends

The diamond market is subject to various trends influenced by economic conditions, technological advancements, and consumer preferences. Understanding these trends is crucial for buyers, investors, and industry professionals.

Economic Factors

The global economy significantly impacts diamond prices. Economic downturns often lead to decreased consumer spending on luxury goods, including diamonds, which can lower prices. Conversely, economic booms can increase demand and drive prices up. Inflation, currency fluctuations, and changes in trade policies also play roles in shaping diamond market dynamics.

Technological Advancements

Advancements in diamond mining and synthetic diamond production have notable effects on the market. Lab-grown diamonds, which are chemically and physically identical to natural diamonds, have gained popularity for their lower cost and ethical considerations. As technology improves, the quality of lab-grown diamonds continues to rise, offering a competitive alternative to natural stones and influencing market prices.

Consumer Preferences

Consumer preferences evolve over time, impacting diamond demand and prices. In recent years, there has been a shift towards ethical sourcing and sustainability. Consumers increasingly seek diamonds with verified origins and ethical mining practices, boosting the market for responsibly sourced gems. Additionally, the rise of personalized and unique jewelry designs has driven demand for custom-cut and colored diamonds.

Investment Demand

Diamonds are also seen as a form of investment. High-net-worth individuals and investors purchase diamonds as a hedge against economic instability and inflation. Investment-grade diamonds, typically those with exceptional quality and larger carat weights, are particularly sought after. The demand from this sector influences prices, especially for rare and high-quality stones.

Online Marketplaces

The growth of online marketplaces has democratized diamond buying, making it more accessible to a broader audience. Online retailers often offer competitive prices compared to traditional brick-and-mortar stores due to lower overhead costs. The convenience and transparency of online shopping have attracted a new generation of diamond buyers, further shaping market trends.

Ethical and Sustainable Practices

The diamond industry has faced scrutiny over ethical issues, including conflict diamonds and environmental impact. In response, there has been a significant push towards ethical and sustainable practices. The Kimberley Process Certification Scheme (KPCS) aims to prevent conflict diamonds from entering the market. Additionally, companies are adopting more sustainable mining practices and supporting local communities, which resonates with socially conscious consumers and influences purchasing decisions.


The price of diamonds per carat today is influenced by a multitude of factors, including carat weight, cut, color, clarity, certification, and broader market trends. Understanding these elements is crucial for anyone looking to purchase or invest in diamonds. With prices ranging from $2,500 to $20,000 per carat and beyond, informed decisions can help buyers get the best value for their investment.
