Our Diamond Price Calculator is expertly calibrated to help you understand and estimate the market values for a diverse array of diamond shapes beyond the traditional round brilliant. This tool is invaluable for individuals and jewelry professionals in Canada (CA), Germany (DE), and Japan (JP) who are exploring the unique appeal of fancy shapes such as Oval, Pear, Emerald, Princess, Cushion, Marquise, Asscher, and Radiant cuts. Whether you're purchasing, selling, or designing with natural or lab-grown (CVD/HPHT) diamonds, understanding the specific valuation factors for each shape is crucial.

While the round brilliant cut is prized for its unmatched sparkle due to standardized optimal proportions, fancy shapes offer a world of personality and style. Each shape has distinct characteristics that influence its beauty, perceived size, and price.

Exploring Popular Fancy Shapes:

• Princess Cut: A square or rectangular brilliant cut with sharp corners, known for its excellent fire and brilliance, second only to the round. It offers a modern look and generally makes good use of the rough diamond crystal, which can translate to a slightly lower price per carat than a round of similar quality.
• Emerald Cut: A rectangular step-cut with cropped corners, featuring long, elegant lines and a "hall of mirrors" effect rather than intense sparkle. Due to its large, open table, clarity is very important in emerald cuts (VS1 or better is often recommended). They can appear larger face-up than other shapes of the same carat weight.
• Asscher Cut: Similar to the emerald cut but square, with deeper cropped corners, creating a distinctive X pattern in the table. It shares the emerald cut's emphasis on clarity and offers a vintage, Art Deco appeal.
• Oval Cut: An elongated brilliant cut that combines the sparkle of a round with a more unique outline. Ovals can appear larger than rounds of the same carat weight and tend to make the finger look longer and slimmer. Watch out for the "bow-tie effect" – a dark, bow-tie shaped area across the center – which should ideally be minimal.
• Marquise Cut: A long, narrow brilliant cut with pointed ends, resembling a boat or a smile. It has one of the largest surface areas of any cut, making it appear very large for its carat weight. Like ovals, it can exhibit a bow-tie.
• Pear Cut (or Teardrop): A hybrid cut combining the rounded end of an oval with the pointed end of a marquise. It's an elegant and versatile shape, often used in pendants and earrings as well as rings. It can also show a bow-tie, and symmetry is critical for its beauty.
• Cushion Cut (or Pillow Cut): A square or rectangular cut with rounded corners and larger facets, offering a softer look with good fire. Antique cushions have a chunkier appearance, while modern cushions are often cut for more brilliance. "Crushed ice" or "pillowy" are terms describing different facet patterns.
• Radiant Cut: A square or rectangular cut that combines the elegance of the emerald cut with the brilliance of the round, thanks to its brilliant-cut facet pattern. It has trimmed corners like an emerald cut but offers more sparkle.
• Heart Cut: A symbolic shape, essentially a pear shape with a cleft at the top. Symmetry is paramount for a beautiful heart shape. It's a more niche choice, often chosen for its romantic appeal.

Valuation Factors Specific to Fancy Shapes:

• Length-to-Width Ratio: For elongated shapes (Oval, Marquise, Pear, Emerald, Radiant), the ratio of length to width significantly affects their appearance. Most people prefer classic ratios (e.g., 1.35-1.50 for ovals, 1.75-2.25 for marquises). Our calculator implicitly considers typical market preferences.
• Cut Quality: While GIA provides full cut grades only for round brilliants, for fancy shapes, polish and symmetry grades are given and are very important. Additionally, factors like table percentage, depth percentage, culet size, girdle thickness, and the presence/absence of a bow-tie are crucial for visual appeal and value. Experts often look for these details beyond just the lab report.
• Market Demand: The popularity of different fancy shapes can fluctuate, influencing their prices. Round brilliants typically command the highest price per carat due to demand and cutting loss (more rough is lost to cut a round). Fancy shapes can sometimes offer better value per carat.
• Carat Weight Retention: Some fancy shapes utilize the rough diamond crystal more efficiently than round cuts, which can sometimes translate into a lower price per carat.

Our Diamond Price Calculator allows you to select a shape and then input the 4Cs:

• Carat Weight: From 0.10 to 50+ carats.
• Color: D-Z scale and considerations for fancy colors.
• Clarity: FL to I3, noting its heightened importance in step-cuts.
• Cut (Polish/Symmetry for Fancies): Recognizing that overall make is critical.

The calculator also differentiates values for Natural Diamonds versus Lab-Grown (CVD/HPHT) Diamonds across all these shapes.
