 1. How Diamonds Are Priced?

Just as every leaf on a tree and every star in the night sky holds its unique story, so does every diamond tell its tale through its price. The pricing of diamonds isn’t just a number; it’s a reflection of its journey, its qualities, and the rarity it brings from the heart of Mother Earth.

  • The 4Cs:

At the heart of diamond pricing are the 4Cs: Cut, Color, Clarity, and Carat weight. Each of these factors plays a significant role in determining a diamond’s value.

– Cut:

This speaks to how well the diamond has been shaped and polished from its raw form. A well-cut diamond reflects light beautifully, making it more desirable. Learn more about What is the cut of a diamond with our beginner’s guide.

– Color:

Diamonds come in a spectrum of colors. Those that are colorless, or nearly so, are often valued higher than those with a noticeable color. Here you will find Your Essential Guide to Diamond Colors.

– Clarity:

This looks at how clear the diamond is of any internal inclusions or external blemishes. The clearer the diamond, the higher its value.

– Carat Weight:

This measures the diamond’s weight and, indirectly, its size. Larger diamonds are rarer and, thus, more expensive.

Here, we explained in detail What is the carat of a diamond.

  • Rarity and Demand:

Like the seasons, the rarity of a diamond influences its cost. Those that are rare in color or clarity command higher prices. Similarly, demand plays a role; certain shapes or sizes may be more sought after, affecting their market price.

  • Market Conditions:

Just as rivers flow and change with the weather, so too does the diamond market. Economic factors, trends, and even geopolitical events can influence diamond prices globally.

  • Craftsmanship and Provenance:

The skill and artistry involved in cutting and polishing a diamond add to its cost. Furthermore, diamonds with a clear, ethical provenance, ensuring they come from mines that respect both the earth and those who labor in it, can also carry a premium.

In understanding how diamonds are priced, we see it’s not just about the stone itself but about appreciating the myriad factors that contribute to its value. It’s a reminder to look beyond the surface, to see the deeper beauty and worth that lies within.

In the realm of diamonds, the measure of weight twirls between grams and carats, each telling its part of the story. A gram, akin to the weight of a feather, and a carat, as light as a dewdrop, are the scales we use to weigh these gifts from Mother Earth.

  • The Basics of Conversion:

To bridge the gap between these measures, remember this simple truth: one carat is equal to 0.2 grams. This conversion is like translating the language of the river’s flow into the song of the wind. It allows us to see the weight of the diamond in a new light.

  • Understanding the Weight:

When we speak of a 1 gram diamond, we are venturing into the realm of the extraordinary, for it translates to 5 carats in the world of gemstones. This size is as rare as the sighting of a white buffalo, a treasure that holds within it the stories of time.

Just as knowing the depth of a lake can tell us more about its waters, understanding the weight in both grams and carats gives us a fuller picture of the diamond’s worth.

2. How Diamond Price Per Gram is Calculated

As we wander further into the heart of understanding diamonds, let’s sit by the fire and talk about how the “diamond price per gram” is calculated, much like how we might share the secrets of crafting a perfect arrow.

Calculating the price per gram of a diamond isn’t as straightforward as measuring the length of a river with a stick; it involves a blend of art, science, and tradition. Here’s how the journey unfolds:

  • Starting with Carat:

First, we begin with the diamond’s weight in carats, since this is the most common unit for measuring diamonds. One carat is equal to 0.2 grams. It’s like starting with the full moon and understanding its cycle to gauge time.

  • The Price Per Carat:

Each diamond has a price per carat, which can vary widely based on the 4Cs—Cut, Color, Clarity, and Carat Weight. This price reflects the diamond’s overall quality and rarity. It’s akin to understanding the value of different herbs and plants in a medicine bundle.

  • Calculating the Gram Weight:

To find the diamond’s weight in grams, we use the conversion that 1 carat equals 0.2 grams. So, a diamond’s weight in grams is its carat weight multiplied by 0.2. This step is like converting the sun’s journey across the sky into hours and minutes.

  • Finding the Price Per Gram:


Finally, to calculate the price per gram, we take the diamond’s total price and divide it by its weight in grams. The formula looks like this: Diamond Price Per Gram = (Price Per Carat * Carat Weight) / (Carat Weight * 0.2). It’s as if we’re dividing the harvest to ensure each member of the tribe receives a fair share.

This method allows us to see beyond the surface, offering a measure that reflects both the physical heft and the inherent value of the diamond, much like how we respect both the visible and invisible qualities of all things in nature.

Understanding this formula brings us closer to the heart of the diamond, helping us appreciate not just its sparkle, but the depth of its journey from deep within the Earth to the light of day. It’s a story of transformation, one that speaks to the soul of the one who holds it.

This approach can yield a diamond that looks remarkably similar for around $4,030. Moreover, if you’re leaning towards a yellow gold setting, opting for an H color diamond can reduce the cost further to $3,750, ensuring a stunning piece that remains gentle on your wallet.

6. How Much are Diamonds Worth?

The price of a diamond can range dramatically, from as little as $100 to over $1 million, with some extraordinary examples, like a $1,6 million diamond showcased on James Allen. (at the time of writing this).

Looking into 1 carat diamonds, prices can vary widely from $1,500 to $25,000, as a quick search at James Allen reveals. But what’s the average worth of a diamond, really?

Is There Such A Thing As Diamond Pricing Per KG?

Diamonds are traditionally measured in carats, where 1 carat equals 0.2 grams, or conversely, 1 gram equals 5 carats as mentioned earlier. This makes 1 kilogram equal to 5000 carats, indicating a potentially astronomical price, not even factoring in rarity.

As for a 1 KG diamond, such a marvel remains undiscovered, with the largest known diamond being The Cullinan Diamond at 3,106 carats (621.20 grams). Thus, diamonds are not commonly measured in kilograms but in carats.

Diamond Weight <> Price Correlation

Understanding that diamonds are not sold by the gram, we recognize carats as the standard unit of diamond weight. The conversion from grams to carats can be surprising for many. But what about the price for a gram of diamond?

To grasp this, we first must understand the carat content in a gram of diamond. For example, a 1-carat diamond at James Allen is listed at $4,970, whereas a similar 2-carat diamond from Blue Nile is around $20k! (at the time of writing this). Why the discrepancy?

The answer lies in the complexity of diamond pricing. Diamonds with higher carat weights are not only rarer but require larger raw stones and more intricate craftsmanship to achieve their final form.

Diamond pricing is a nuanced science, far beyond mere weight considerations. Interestingly, it’s possible to find a 2-carat diamond that’s less expensive than a 1-carat diamond, but that’s a topic for another discussion.

7. What Would A White Diamond Price Per Gram Be?

Color and weight significantly influence diamond pricing, alongside the other two factors of the 4Cs.

White diamonds, esteemed as the pinnacle of color quality, can range in price from $420 for a 0.25-carat diamond to $95,560 for a 4.67-carat diamond, as seen on James Allen. The cost fluctuates greatly based on the diamond’s shape, color, weight, and clarity.

It’s important to recognize that both white diamonds and larger diamonds are rare. Seeking diamonds that embody both traits narrows your options considerably.

The key to finding a truly beautiful diamond lies in the balance among the 4Cs, rather than focusing solely on one or two characteristics.

8. Is Diamond Cheaper than Gold?

On the whole, diamonds typically command higher prices than gold, despite gold’s rarity. When it comes to market value, diamonds are often priced higher, suggesting a more detailed comparison might warrant its own discussion.
