When we hear “24 carat,” most people immediately think of pure gold. However, in some conversations, especially among non
-experts, the term “24 carat diamond” also appears. While not technically common in gemology, it refers to a diamond weighing
24 carats—a rare and extraordinary size. In this article, we will explore what the 24 carat diamond price truly means, what factors
influence it, and how such a rare gemstone is valued and perceived in the global market.
Understanding Carat in Diamonds
A carat is a unit of weight used specifically for gemstones. One carat equals 200 milligrams or 0.2 grams. So a 24 carat diamond
weighs approximately 4.8 grams. While that may sound small in everyday terms, in the world of diamonds, it’s enormous. The
majority of diamonds used in jewelry are less than 1 carat.
How Rare Is a 24 Carat Diamond?
Diamonds weighing 24 carats are exceptionally rare. Most diamond mines yield small stones, and finding a single crystal that can be
cut into a 24 carat polished diamond is extremely uncommon. In fact, fewer than a handful of such diamonds enter the market each
year, and often they are bought by private collectors or displayed in museums.
Factors Affecting the Price
Just like smaller diamonds, the price of a 24 carat diamond is determined by the 4Cs:Carat Weight – At 24 carats, the weight alone
increases its value exponentially.Cut Quality – A well-cut diamond will reflect light beautifully, maximizing brilliance.Color – Colorless
diamonds (graded D) fetch the highest prices.Clarity – Diamonds with fewer inclusions or blemishes are far more valuable.In large
diamonds, even minor imperfections can drastically affect price because they are more visible.
Estimated Price Range
The price of a 24 carat diamond can vary significantly depending on quality. Here are general estimates:Low to medium quality:
$500,000 to $2 millionHigh quality (excellent cut, D color, IF clarity): $4 million to over $10 millionFamous or historic diamonds:
Pricelessor auctioned for tens of millionsAn example is the “Graff Pink”, a fancy pink diamond weighing 24.78 carats, which sold
for over $46 million.
Why the Term “24 Carat Diamond” Can Be Confusing
The term “24 carat” is commonly associated with gold, where it refers to purity (99.9%), not weight. In contrast, for diamonds,
“carat” has no connection to purity—only to weight. So when people say “24 carat diamond,” they often mean either a very large
diamond or are mistakenly using gold terminology.
Investment Value and Market Demand
Due to its rarity, a 24 carat diamond is considered more than a piece of jewelry—it’s an investment. High-net-worth individuals
often buy such diamonds as a store of value. Over time, rare diamonds have shown consistent appreciation, especially colored
ones or those with historic provenance.
