How Does Diamond Shape Affect Quality and Price?

When selecting the perfect diamond, there is more to consider than just the “Four Cs” (Carat, Cut, Color, and Clarity). The choice of shape also plays a pivotal role in the selection. The diamond shape not only affects its visual appeal but also profoundly impacts its overall quality and, consequently, its price.

 

From the classic round brilliant to the princess cut, each diamond shape carries unique characteristics that influence not just the sparkle but the entire essence of the gem. This article will examine the intricate relationship between the shape, quality, and price of diamonds.

 

 

The Diamond Shapes

 

Diamond artisans skillfully shape diamonds – from round and oval – to modern choices such as princess, emerald, and asscher cuts. Each diamond shape possesses distinct visual characteristics that influence how light interacts with the stone, resulting in varying brilliance, fire, and scintillation levels.

 

Round Brilliant: This is the classic diamond shape with a circular outline. It has many facets that make it sparkle a lot. It is timeless and goes well with any jewellery style.

 

Princess: The Princess cut is square or rectangular. It’s known for its sharp corners and brilliant sparkle. It is a popular choice for engagement rings.

 

Emerald: The Emerald cut has a rectangular shape with stepped facets, giving it a clean and elegant appearance. They are great for showcasing a diamond’s clarity.

 

Asscher: The Asscher cut is similar to the Emerald cut but square in shape, with a distinctive “hall of mirrors” effect due to its step-like facets.

 

Pear: The shape looks like a teardrop, with one end rounded and the other pointed. It is unique and can make fingers appear longer when worn as a ring.

 

Marquise: The Marquise cut is like an elongated oval with pointed ends. It is distinctive and can make a diamond look more extensive due to its shape.

 

Oval: The Oval shape is similar to the round brilliant but elongated. It gives a classic look with a modern twist.

 

Heart: The Heart shape is romantic and unmistakable, resembling a heart. It is a symbol of love and makes for eye-catching jewellery.

 

Cushion: The Cushion cut has rounded corners and larger facets, giving it a vintage and romantic appeal.

Impact of Diamond Shapes on Quality Characteristics

 

Cut

The cut of a diamond, often confused with its shape, refers to the quality of how well the diamond’s facets interact with light. A well-cut diamond maximises its brilliance and fire, giving it that captivating sparkle. The round brilliant cut exhibits the most brilliance among different diamond shapes due to its specific facet arrangement and proportions. On the other hand, particular shapes, like the emerald cut or the asscher cut, prioritise clarity over brilliance, showcasing a hall-of-mirrors effect.

 

Clarity

It refers to internal or external flaws, known as inclusions and blemishes, respectively. The impact of diamond shape on clarity perception varies. Owing to their brilliant faceting, round diamonds can better disguise minor flaws. In contrast, step-cut shapes like emeralds and baguettes make inclusions more visible due to their open facets. Hence, these shapes demand higher clarity grades to maintain visual appeal.

 

Color

The choice of diamond shape can also influence how color is perceived. Round diamonds hide color better due to their intricate faceting and light play, making lower color grades less noticeable. In contrast, elongated shapes like the marquise or pear can emphasise color, especially towards the tips. Hence, consumers often select higher color grades for these shapes.

Price Dynamics for Shapes of Diamond

 

The complex interplay between different shapes of diamond, quality, and price makes each gem unique. Here is how these factors impact the price range:

 

Round vs. Fancy Shapes

The classic round brilliant diamond typically demands a premium due to its popularity and optimal light performance. Fancy shapes, such as princess, cushion, and radiant, can be affordable alternatives without sacrificing visual impact. These shapes often retain more of the original rough diamond, resulting in less wastage during the cutting process and lower prices.

 

Cut Quality and Price

A diamond’s cut quality correlates with its price. Regardless of shape, a well-cut diamond commands a higher price due to its enhanced brilliance and sparkle. Lesser-quality cuts, on the other hand, might come at a more budget-friendly cost. For the best possible sparkle, buyers should be ready to invest in a higher-cut quality, regardless of shape.

 

Clarity and Color Influence

The impact of diamond shape on clarity and color perception can influence pricing. Shapes that tend to reveal inclusions, like emerald or asscher, necessitate higher clarity grades, which can escalate the price. Similarly, buyers might opt for a higher color grade if a particular shape accentuates color, as seen with some elongated cuts, affecting the final cost.

 

Market Trends and Rarity

While the round brilliant remains a timeless favourite, the unique shape might experience fluctuations in demand. Initially, uncommon shapes might have a lower price, but their value could appreciate if they become popular over time. Rarity can be a double-edged sword – making a diamond more enticing and escalating its price.

 

 

Looking for Premium Value and Quality Diamonds? 

 

The diamond shape is not just an aesthetic choice but a transformative decision that intertwines quality and value. Generally, round diamonds often carry a higher price tag than other fancy colour diamonds. Each diamond shape comes with its own set of advantages and disadvantages.

Encyclopedic coverage of diamond price and diamond resale value

The diamond price volatility is an everlasting debate amongst the people like 

Why are diamonds very expensive?

Why does each diamond have a distinct yet discrepant price?

How is the diamond price calculated?

What are the factors that affect the diamond price?

How is the diamond resale value decided?

How to safeguard yourself from any fraudulent activities when purchasing the diamond?

Well, then you have come to the right place. Keep calm and carry on reading. We are presenting you with our comprehensive analysis of diamond pricing which will solve all your queries.  

The world luxury itself is regarded as the synonym of expensive. Well to some extent it is true, but even in luxury goods, the rare earth metals tend to be more expensive.

But the diamond has something more to it. Apart from being a rare earth element, its higher prices are due to many other reasons such as diamond mining needs both capital resources and human resources in overabundance, large (and costly) supply chain, higher demand and limited supply, etc. 

But we are here to discuss the quality and brilliance of a diamond that affects its prices apart from the other market factors. 

But before going further, let’s clear one thing: the diamonds are always valued and traded on per carat basis. For example $3000 0.5-carat diamond costs $6000 per carat. However, the retailers generally state the total diamond price (Price per Carat x Carat Weight), not per-carat price. 

There are many companies that release periodic reports on per carat diamond prices such as International Diamond Exchange (IDEX), World Federation Diamond Trading Platform (WFDB), Israel Diamond Institute (IDI), Rapaport, etc.

Fundamental factors that decide the diamond price:

The diamond price is primarily decided based on its 7 elementary characteristics including 4Cs, Certification, shape, and fluorescence. Let’s understand each of them in detail:

Carat:

As we all know that the price of a diamond increases with increased carat weight but not in proportion; meaning that a 2-carat diamond will undoubtedly be more expensive than a 1-carat diamond, but not necessarily be twice the price of a 1-carat diamond. 

The total diamond price hike abruptly at popular carat weights such as 0.50ct, 0.70ct, 1.00ct, 1.50ct, 2ct, 3ct, 5ct, and so on; due to their greater demand.

These numbers of carat-weights are often referred to as the ‘Magic Marks’. The 1.00ct mark is the best-known example of this, as putting all the characteristics the same; a 1.00ct diamond might be significantly more expensive than the 0.98ct, but there will be a minor price difference between 0.96ct diamond and 0.98ct diamond. 

Color:

The diamond price increases proportionally with the near colorlessness of the diamond, assuming all the other characteristics being the same. Colorlessness here refers to the absence of yellow (be it visible or not) tint in the stone. 

Clarity:

The clarity of a diamond refers to the absence of inclusions (foreign particles) in the stone. The diamonds with no or fewer inclusions are always of premium prices.

But the interesting thing about clarity is that diamonds with the same clarity grade can significantly vary in price, depending upon how visible their inclusions are through the naked eye (eye clean diamonds).

Cut:

The well-cut diamonds with ideal proportions of facet and their symmetrical positions with respect to each other are usually rarest of the rare and more expensive. For example, diamonds with too thick or too thin girdles are often sold at a discounted price. 

The culet is also an important factor in diamond pricing. Cutlet is nothing but the bottom facet of the diamond. The ideal diamond should have no or small cutlet and those diamonds sold at premium prices.

The cut of the diamond closer to its ideal proportions makes it more expensive. 

Shape:

The cut and shape of the diamond are often confused with each other as the diamond shape name also has a word cut in it such as round cut, princess cut radiant cut, etc. 

But there is a subtle difference between the two, and the difference is:

The shape of the diamond referred to as its physical appearance like round, oval, heart, square, etc. While the cut refers to the proportions of its facet for any said shape.

The famous round cut and the princess cut are more expensive than the pear cut or the trilliant cut as the former requires larger rough diamond compared to later.

Fluorescence:

The fluorescence of a diamond is a measure of its luster under UV light; the higher the level of fluorescence the diamond appears hazier. Usually depending upon the type of fluorescence lowers the price of a diamond.

However, there are some exceptions where the diamond price is not compromised due to the presence of fluorescence. 

For example, in diamonds of H to I color grade; the presence of Medium fluorescence (blueish) could make the stone look whiter and brighter. 

Certification:

The diamond price also changes when the gemological laboratory that issued the certificate for the diamond changes. For example, the GIA certified diamonds are usually more expensive than any other lab-certified diamonds.

Now you might be wondering why do diamonds having all the above-stated characteristics be equal and still differ in price? So let’s understand the additional factors that affect the diamond price. 

Secondary factors affecting the diamond price:

Usually, the diamond price is calculated on a reasonable combination of both primary and secondary factors. But here we have included separately for your convenience. 

In-house vs online purchase:

The traditional diamond retail market is often slightly more expensive for consumers than virtual retail due to the additional costs for operations and maintenance in the former. 

But at HK, we have eliminated this discrepancy, and to protect the consumer rights, we are practicing Fair and Fixed Policy for diamond pricing globally.

Market volatility:

Similar to any other goods or services in the market, the diamond prices are also hugely driven by demand and supply which depend on consumer behavior, economic growth, local interest rates of taxes, production, seasonality, etc.

Sometimes the additional benefits including diamond insurance, guarantee/warranty, upgraded service, etc., offered by the particular retailer also indirectly affect the diamond price.

You might be wondering that the resale value of diamonds is estimated in the same way or there is a different method? – well, let’s see:

How is the diamond resale value decided?

Re-selling your diamond is might be an overwhelming process but understanding how diamonds are priced for resale becomes essential to keep yourself away from any loss or fraud.

Normally any product is out for resale it always expected to worth less than the original market price, the same goes for the diamond resale value.

The diamond resale price then depends on where it is being resold: whether in the trade or directly to the end consumer.

The diamond price often depreciates over time due to many reasons including the already way much high initial retail prices, also sometimes a Resale Appraisal (fair market value of the diamond) is done on the purpose of valuing the diamond with the intention of it being resold in advance.

If we take an example of let’s say any diamond at $5000 retail price. And if we disclude all the taxes and duties it costs $4500. Then, considering the trade contract, retail appraisers, overhead costs, and extra associated costs and after excluding them; the resale price of the same diamond would be somewhere between $1,500 to $2,500.
