Marquise Brilliant Cut Lab Grown Diamond

Introduction

Elegant, distinctive, and designed to make a statement, the Marquise Brilliant Cut Lab Grown Diamond is a beautiful choice for modern custom jewelry. Recognized by its long, pointed silhouette, the marquise shape creates an elegant appearance while offering impressive visual presence.

Its brilliant-style faceting is designed to create lively sparkle, while the elongated outline can make the diamond appear larger and visually lengthen the finger. GIA notes that marquise diamonds are especially distinctive because of their elongated shape and two pointed ends.

At Bespoke Carat, Marquise Brilliant Cut Lab Grown Diamonds provide an exciting foundation for creating sophisticated engagement rings, statement jewelry, and personalized designs that combine classic elegance with contemporary style.

What Is a Marquise Brilliant Cut Lab Grown Diamond?

A Marquise Brilliant Cut Lab Grown Diamond is a laboratory-grown diamond fashioned into the distinctive marquise shape and cut with a brilliant-style facet arrangement.

The marquise shape has two curved sides that taper into pointed ends, creating a long and slender silhouette. The brilliant faceting is designed to interact with light and create brightness, fire, and scintillation.

The shape is also known as the navette cut, and its elongated outline gives it a distinctive presence compared with round, oval, or cushion-shaped diamonds.

Laboratory-grown diamonds are real diamonds with the same fundamental crystal structure and many of the same physical and optical properties as natural diamonds. They can be produced using methods such as CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature).

Why Choose a Marquise Brilliant Cut Lab Grown Diamond?

1. Distinctive Elongated Shape

The most recognizable feature of the marquise diamond is its long, pointed silhouette.

Unlike a round diamond, the marquise creates a more dramatic and directional appearance. This makes it particularly appealing for people who want a diamond that feels elegant but less traditional.

2. Impressive Visual Presence

The elongated shape can provide substantial face-up coverage relative to its carat weight. GIA notes that marquise diamonds can create the illusion of a larger stone and can visually elongate the finger.

This makes the marquise an attractive option for buyers who want a statement-making center stone.

3. Brilliant Sparkle

A marquise brilliant cut uses brilliant-style faceting to create lively light performance.

When well proportioned, the diamond can display beautiful flashes of brightness and scintillation across its elongated surface.

4. Perfect for Unique Jewelry

The marquise shape gives designers plenty of creative freedom.

It can be used in:

• Engagement rings
• Three-stone rings
• Halo rings
• Wedding bands
• Pendants
• Earrings
• Cocktail rings
• Custom statement jewelry

The Unique Shape of a Marquise Diamond

A marquise diamond has several defining characteristics.

Two Pointed Ends

The sharp points at both ends create the signature marquise silhouette.

Curved Wings

The sides curve outward from the center before gradually narrowing toward the points.

Elongated Body

The long central body gives the diamond its elegant appearance and contributes to its strong visual presence.

Symmetrical Outline

Symmetry is especially important for marquise diamonds. Ideally, the two halves should appear balanced, with the points aligned and the curves matching on both sides. GIA highlights symmetry as an important factor in evaluating the visual appeal of marquise diamonds.

Why Symmetry Matters in a Marquise Brilliant Diamond

Symmetry is one of the most important characteristics to evaluate when choosing a marquise diamond.

Because the shape is elongated and pointed at both ends, even relatively small differences between the two sides can become noticeable.

When viewing a marquise diamond, look for:

• Aligned points
• Balanced wings
• Similar curves on both sides
• Consistent facet patterns
• A centered outline
• No obvious unevenness

GIA recommends comparing the two halves of the diamond and checking that the outline and facets are balanced.

A well-symmetrical marquise can look refined and elegant, while an uneven shape may appear less harmonious.

Marquise Diamond Length-to-Width Ratio

The length-to-width ratio describes how long and slender a marquise diamond appears.

A wider marquise has a fuller and more substantial appearance, while a longer marquise creates a slimmer and more dramatic look.

There is no single ratio that is perfect for every design. Your preferred proportion should depend on the style you want to achieve.

For example:

Wide Marquise

A fuller silhouette with softer visual proportions.

Classic Marquise

A balanced combination of length, width, curves, and pointed ends.

Elongated Marquise

A longer, more dramatic appearance that emphasizes the finger-lengthening effect.

GIA has noted that marquise diamonds can vary considerably in proportion and that personal preference plays an important role in selecting the shape.

The 4Cs of a Marquise Brilliant Cut Lab Grown Diamond

1. Cut

For a marquise diamond, don't focus only on a simple cut grade.

Instead, consider:

• Proportions
• Symmetry
• Polish
• Facet arrangement
• Light performance
• Bow-tie effect
• Overall shape appeal

GIA's standard overall cut-grade system is primarily associated with standard round brilliant diamonds, so fancy shapes such as marquise require closer visual evaluation.

A beautiful marquise should appear balanced, lively, and symmetrical.

2. Color

Diamond color describes the amount of body color visible in the stone.

The traditional D-to-Z scale progresses from colorless toward increasingly noticeable yellow or brown tones.

Your ideal color depends on your preferred appearance and the metal chosen for your jewelry.

A colorless-looking marquise can create a crisp and bright appearance, while a slightly warmer diamond can complement yellow or rose gold beautifully.

3. Clarity

Clarity refers to internal inclusions and surface blemishes.

When choosing a marquise diamond, consider whether inclusions are visible to the naked eye and whether they affect the stone's beauty.

Instead of automatically selecting the highest clarity grade, focus on the actual appearance of the diamond and how clean it looks when viewed normally.

4. Carat Weight

Carat weight refers to the diamond's weight rather than its exact visual dimensions.

Because marquise diamonds have an elongated outline, they can provide substantial face-up coverage for their carat weight.

When comparing two marquise diamonds, consider:

• Carat weight
• Length
• Width
• Depth
• Face-up dimensions
• Overall proportions

Best Settings for Marquise Brilliant Cut Lab Grown Diamonds

Solitaire Setting

A solitaire allows the marquise diamond to remain the main attraction.

Its elongated shape naturally creates a sophisticated and elegant center without requiring additional stones.

Halo Setting

A halo of smaller diamonds can follow the marquise outline, emphasizing its elongated silhouette while adding extra brilliance.

Three-Stone Setting

A marquise center can be paired with complementary side stones such as:

• Trapezoid diamonds
• Pear diamonds
• Baguettes
• Half moons
• Round diamonds

This creates a beautiful combination of shapes and proportions.

Bezel Setting

A bezel provides a sleek, contemporary appearance while surrounding the diamond with metal.

East-West Setting

For a modern twist, the marquise can be positioned horizontally across the finger.

This creates a bold, fashion-forward look and is an excellent choice for custom engagement rings.

Marquise Brilliant Cut Lab Grown Diamond for Engagement Rings

A Marquise Brilliant Cut Lab Grown Diamond can make an unforgettable engagement-ring center stone.

Its distinctive silhouette gives the ring a strong visual identity, while the brilliant faceting provides sparkle.

Popular design options include:

• Classic solitaire
• Halo engagement ring
• Three-stone ring
• Pavé band
• Hidden halo
• East-west ring
• Bezel setting
• Cathedral setting
• Vintage-inspired ring
• Modern geometric ring

Because the marquise is such a recognizable shape, even a simple setting can make a strong statement.

Marquise Diamond with Side Stones

One of the most exciting aspects of custom jewelry is combining different diamond shapes.

Marquise + Trapezoid

The pointed, curved marquise contrasts beautifully with the architectural lines of trapezoid side stones.

Marquise + Half Moon

Half-moon diamonds can create a smooth transition around the center stone, making them ideal for elegant three-stone designs.

Marquise + Pear

Pairing a marquise center with pear-shaped side stones creates a graceful combination of elongated and curved shapes.

Marquise + Baguette

Baguette side stones introduce clean linear geometry and create a sophisticated modern appearance.

Marquise + Round Diamonds

Smaller round diamonds can add additional brilliance while keeping the overall design classic.

East-West Marquise Diamond

Traditional marquise diamonds are usually set vertically, with the long axis running along the finger.

However, an east-west marquise setting turns the diamond horizontally.

This changes the entire personality of the ring.

Instead of appearing traditional and elongated, the horizontal marquise creates a contemporary, unconventional look.

It works particularly well for:

• Minimalist rings
• Modern engagement rings
• Bezel settings
• Low-profile designs
• Fashion-forward custom jewelry

For someone looking for an engagement ring that feels unique, an east-west marquise can be an excellent design choice.

Marquise Brilliant Cut Lab Grown Diamond for Pendants

The elongated shape of a marquise diamond also makes it ideal for pendant designs.

A vertically positioned marquise can create a graceful, streamlined pendant, while a horizontal orientation can create a more contemporary appearance.

Marquise diamonds can be incorporated into:

• Solitaire pendants
• Halo pendants
• Cluster designs
• Diamond station necklaces
• Custom geometric pendants

At Bespoke Carat, the shape can be customized to complement the overall proportions and style of the jewelry.

How to Choose the Right Marquise Brilliant Cut Lab Grown Diamond

Before choosing your diamond, consider these important factors.

1. Check Symmetry

Make sure the two halves of the diamond appear balanced.

2. Examine the Points

The two tips should align and look well defined.

3. Evaluate the Bow-Tie

Some bow-tie contrast is common, but avoid a center that looks excessively dark or distracting.

4. Consider the Length-to-Width Ratio

Choose a wider or more elongated shape according to your desired design.

5. Compare Actual Measurements

Carat weight alone does not tell you how large the diamond will appear from the top.

6. Inspect the Diamond Face-Up

Look at the diamond without magnification under normal lighting and from a normal viewing distance.

7. Consider the Setting

Make sure your setting provides adequate protection for the pointed ends.

8. Review the Diamond Report

If your stone comes with a laboratory report, verify the information and make sure the report corresponds to the diamond. GIA laboratory-grown diamond reports can include information such as color, clarity, carat weight, and laboratory-grown identification.
