Explore the profound impact of a diamond's shape on its price in our comprehensive guide. From classic round cuts to trendy radiant & marquise cuts, discover how to make the perfect choice when selecting a diamond for your dream engagement ring or fine jewelry.

When buying a diamond, it's crucial to consider its shape as it directly influences the price. Due to market demand & higher manufacturing costs, round diamonds, the most common shape, generally command a higher price compared to fancy-shaped diamonds. This is attributed to their exceptional brilliance & popularity.

Why Are Some Diamonds More Expensive Than Others?

Round one is the most common & expensive due to the significant amount of waste produced during the cutting process & the need for more raw diamonds. Despite being more affordable, princess cut & cushion cut diamonds remain in high demand thanks to their unique faceting patterns.

On the other hand, elongated shapes like oval-cut & emerald-cut diamonds have fewer facets yet still offer excellent clarity, making them comparatively cheaper. The most economical options are pear-shaped & marquise-cut diamonds, as they are less commonly found. 

However, they are still excellent choices for those who appreciate distinctive & alluring diamond shapes.

What Is The Cheapest Diamond Shape?

The marquise cut is often the more affordable option when it comes to diamonds. These cuts, while less common than round, princess & cushion cuts, tend to come with a lower price tag.
