Which Diamond Shape Is the Most Expensive to Buy?

Round Brilliant Diamonds: The Premium Choice

When it comes to diamond pricing, the round brilliant cut reigns supreme as the most expensive diamond shape on the market. At PHD Jewelers in Wayne, we often guide customers through the nuances of diamond selection, explaining why round brilliants command premium prices.

The round brilliant’s higher cost stems from several factors. First, the cutting process for round diamonds typically results in more rough diamond waste—sometimes up to 60% of the original stone is lost during cutting. This material loss must be factored into the final price. Additionally, the popularity of round engagement rings in Philadelphia creates consistent demand, keeping prices elevated.

The exceptional brilliance of round diamonds also justifies their higher price point. With 57 or 58 facets strategically positioned to maximize light return, round brilliants offer unparalleled sparkle. This superior light performance is why many couples visiting our King of Prussia jewelry store ultimately choose round diamonds despite the higher investment.

Fancy Shapes: Comparing Costs

Fancy-shaped diamonds—any shape other than round—generally cost less than their round counterparts. Among these alternative shapes, some command higher prices than others. Oval and cushion cuts have gained tremendous popularity for engagement rings in Wayne in recent years, causing their prices to increase accordingly.

Marquise and pear-shaped diamonds offer excellent value, often appearing larger than their actual carat weight due to their elongated shape. Meanwhile, princess cuts typically sell for approximately 25-35% less than round brilliants of comparable quality. For customers at our Philadelphia jewelry store, this represents significant savings while still enjoying a brilliant, modern diamond shape.

Heart-shaped diamonds, popular for romantic gestures, command higher prices among fancy shapes due to their complex cutting requirements and symbolic appeal. When crafting custom jewelry in Philadelphia, we find that the intricacy of setting heart-shaped diamonds also contributes to their higher overall cost compared to simpler fancy shapes.

Factors That Affect Diamond Pricing

Beyond shape, numerous factors influence a diamond’s price. The traditional 4Cs—cut, color, clarity, and carat weight—remain fundamental. Carat weight has the most dramatic impact, with prices increasing exponentially rather than linearly as size increases. At PHD Jewelers in Philadelphia, we explain to customers that a 2-carat diamond typically costs significantly more than twice the price of a 1-carat diamond of equal quality.

Cut quality dramatically affects a diamond’s brilliance and, consequently, its value. Excellently cut diamonds command premium prices regardless of shape. When customers explore lab-grown diamonds in King of Prussia, we emphasize that cut quality remains just as important as with natural diamonds.

Color and clarity grades also significantly impact pricing. Near-colorless diamonds (G-H color) offer excellent value compared to completely colorless stones, while VS1-VS2 clarity grades provide the sweet spot of being eye-clean without the premium of flawless diamonds. For wedding rings in Wayne, these balanced quality choices often yield the best value for couples on a budget.

Market trends and diamond certification further influence pricing. GIA-certified diamonds typically command higher prices than those with alternative certifications due to the institute’s rigorous standards and market reputation. Our diamond jewelry collections in Philadelphia feature predominantly GIA-certified stones for this reason.

Price Comparison of Different Diamond Shapes

To illustrate price differences between shapes, let’s compare relative costs for a 1-carat diamond of similar quality across various shapes, with round brilliant set at 100% for reference:

• Round Brilliant: 100% (most expensive)
• Heart Shape: 85-95%
• Oval: 80-90%
• Marquise: 80-85%
• Pear: 80-85%
• Emerald Cut: 75-85%
• Cushion Cut: 75-85%
• Princess Cut: 70-80%
• Asscher Cut: 70-80%
• Radiant Cut: 70-80%

These percentages can fluctuate based on current market trends. At PHD Jewelers in King of Prussia, we’ve noticed increasing demand for oval and cushion cuts, which has gradually narrowed their price gap with round brilliants.

For shoppers seeking engagement rings in King of Prussia, understanding these relative price differences can help maximize budget while achieving the desired aesthetic. Many customers are surprised to learn they can purchase a larger fancy-shaped diamond within the same budget they had allocated for a smaller round diamond.

Best Value Diamond Shapes

For buyers prioritizing maximum value, certain diamond shapes consistently offer better price-to-size ratios. Emerald and Asscher cuts, with their step-cut faceting patterns, typically cost less than brilliant cuts while offering elegant, sophisticated appeal. These cuts are particularly popular for wedding rings in Philadelphia where understated elegance is desired.

Princess cuts deliver excellent value, offering the square shape many desire at a significantly lower price point than rounds. Their brilliant faceting pattern provides comparable sparkle to round diamonds, making them popular choices for diamond rings in King of Prussia.

Marquise, pear, and oval cuts create the illusion of greater size due to their elongated shapes, offering excellent spread (visible surface area) for their carat weight. This face-up size advantage makes them popular choices at our King of Prussia diamond jewelry showroom, especially for customers seeking maximum visual impact.

Cushion cuts blend vintage appeal with modern brilliance at a favorable price point, making them increasingly popular for custom engagement rings in Philadelphia. Their soft corners and brilliant faceting create a romantic aesthetic that many couples prefer over the more common round brilliant.

Investment Potential of Different Diamond Shapes

From an investment perspective, round brilliant diamonds typically hold their value better than fancy shapes. Their timeless appeal and consistent demand create a more stable resale market. At PHD Jewelers in Philadelphia, we often advise customers considering investment aspects to lean toward round diamonds if value retention is a priority.

Among fancy shapes, those with enduring popularity like oval and cushion cuts tend to hold value better than more distinctive or trend-driven shapes. The market for lab-grown diamonds in Philadelphia follows similar patterns, though with different value considerations than natural diamonds.

It’s worth noting that diamonds, regardless of shape, should primarily be purchased for their beauty and emotional significance rather than as financial investments. The diamond earrings in Wayne and other diamond jewelry we sell are primarily purchased for their beauty, symbolism, and emotional value—their potential resale value is secondary.

Conclusion: Making the Right Choice

While round brilliant diamonds remain the most expensive shape on the market, the “right” diamond shape depends on personal preferences, budget considerations, and style priorities. At PHD Jewelers in King of Prussia, we encourage customers to balance budget with aesthetic preferences when making this important decision.

For maximum brilliance regardless of cost, round diamonds remain unmatched. For those seeking excellent value without compromising beauty, princess, cushion, and oval cuts offer compelling alternatives. Unique styles might gravitate toward marquise, pear, or heart shapes, while vintage enthusiasts often prefer emerald or Asscher cuts.

Remember that diamond shape is ultimately a personal choice that should reflect the wearer’s style and preferences.
