History of Marquise Cut Diamonds

The marquise cut dates back to 18th-century France, where King Louis XV commissioned a diamond cut that resembled the smile of his mistress, Marquise de Pompadour. The result was a long, narrow shape with pointed ends—refined and romantic, much like its muse.

Over the centuries, the marquise cut has symbolized royalty, passion, and prestige. Its elongated form became especially popular during the Art Deco era, and today, it continues to represent individuality and elegance in engagement jewelry.

Understanding the Marquise Cut

A marquise diamond has 56 to 58 facets, designed to enhance brilliance and make the stone appear larger than its actual carat weight. The shape’s proportions—long and tapered—create the illusion of greater size and slender fingers.

Key Characteristics

• Shape: Elongated with two pointed ends and curved sides.
• Facets: Typically 58, similar to a round brilliant cut.
• Length-to-Width Ratio: Ideal between 1.75 and 2.25 for a balanced shape.
• Brilliance: High, due to brilliant-cut facets.
• Bow-Tie Effect: A dark area that appears across the center if the cut is not well-proportioned

When cut perfectly, the marquise diamond delivers exceptional sparkle and visual drama.

Pros

• Appears Larger: The elongated shape gives more surface area, making it look bigger per carat.
• Finger-Lengthening Effect: Creates a slender, graceful look on the hand.
• Brilliant Sparkle: Facet pattern ensures excellent light reflection.
• Unique Shape: Stands out from classic round or princess cuts.
• Great Value: Often more affordable than rounds of the same carat.

Cons

• Prone to Chipping: The pointed ends require protective prongs.
• Visible Bow-Tie Effect: Poorly cut stones may show dark areas in the center.
• Symmetry is Crucial: Even slight asymmetry can affect appearance.
• Shows Flaws Easily: Inclusions near the tips are more noticeable.

Price and Value of Marquise Cut Diamonds

Marquise cut diamonds are 10–25% less expensive than round diamonds due to lower demand. Their shape also gives you more visible surface area per carat, offering excellent value for money.

Buying Tips:

• Focus on excellent symmetry to avoid uneven ends.
• Choose VS2 clarity and G–H color for best beauty-value ratio.
• Protect the tips with prongs or a bezel setting.

Marquise Cut Diamonds Care and Maintenance

• Clean gently with mild soap and warm water using a soft brush.
• Avoid harsh chemicals or ultrasonic cleaners for daily care.
• Have prongs checked regularly to protect the pointed tips.
• Store separately to prevent scratching.
