Best Portrait Cut Diamonds Guide

Portrait Cut Diamonds are among the rarest and most distinctive diamond cuts in the world. Known for their flat, transparent appearance and antique charm, these diamonds are prized by collectors and jewellery lovers who value history, craftsmanship, and individuality over modern sparkle. Unlike traditional diamond cuts, portrait cut diamonds focus on clarity, surface beauty, and artistic expression.

At Opulent Diam, portrait cut diamonds are appreciated for their elegance, rarity, and deep historical significance. This complete guide will help you understand what portrait cut diamonds are, their origins, characteristics, uses, and how to choose the best one for your jewellery.

What Are Portrait Cut Diamonds?

A Portrait Cut Diamond is a very thin, flat diamond with a large surface area and minimal or no faceting. These diamonds are usually rectangular, square, or slightly irregular in shape and are known for their glass-like transparency rather than sparkle.

Historically, portrait cut diamonds were designed to sit over miniature paintings or photographs, allowing the image beneath to remain visible. This unique purpose is what gives the cut its name.

Key Characteristics of Portrait Cut Diamonds

Portrait cut diamonds are instantly recognizable because they look very different from modern diamonds.

Main Features:

Extremely thin and flat profile
Minimal or no facets
Large surface area
Soft shine instead of sparkle
High transparency

Because of their structure, portrait cut diamonds do not reflect light like brilliant cuts. Their beauty lies in their clarity, subtle glow, and antique aesthetic.

History of Portrait Cut Diamonds

Portrait cut diamond originated in the 16th and 17th centuries, primarily in Europe. During this time, diamonds were cut by hand using simple tools, and candlelight was the main source of illumination.

These diamonds were often placed over:

Miniature portraits
Locks of hair
Painted scenes
Religious symbols

They were especially popular among royalty and aristocracy, making them highly symbolic and personal pieces of jewellery. Today, genuine portrait cut diamonds are considered rare historical treasures.

How Portrait Cut Diamonds Are Different from Other Antique Cuts

Portrait cut diamonds are often compared with other antique cuts, but they are unique in both form and purpose.

Compared to Rose Cut Diamonds

Rose cuts have a domed top with facets
Portrait cuts are flat and smooth
Rose cuts offer a soft glow, portrait cuts offer transparency

Compared to Old Mine or Old European Cuts

Old cuts are thicker with visible sparkle
Portrait cuts are thin and do not sparkle
Portrait cuts emphasize artistry over brilliance

This makes portrait cut diamond ideal for collectors and bespoke jewellery rather than traditional engagement rings.

Why Portrait Cut Diamonds Are So Rare

Portrait cut diamonds are rare for several reasons:

They require specific rough diamond shapes
Cutting mistakes can easily damage the stone

Most existing stones are antiques

Because of this, authentic portrait cut diamonds are highly valued and difficult to source.

Clarity and Transparency in Portrait Cut Diamond

Clarity is the most important factor in a Portrait Cut Diamond. Since these diamonds are flat and transparent, inclusions are easily visible.

What to Look For:

Clean, clear appearance
Minimal visible inclusions
Even transparency across the surface

Unlike modern diamonds, traditional clarity grades may not always apply, so visual inspection is essential.

Color in Portrait Cut Diamonds

Portrait cut diamond often appear slightly warm in color. This warmth enhances their antique appeal and pairs beautifully with yellow gold or rose gold settings.

Many buyers prefer natural, soft tones rather than icy white colors, as it maintains the historic and artistic feel of the diamond.

Popular Uses:

Antique-style rings
Lockets and pendants
Statement earrings
Custom heirloom jewellery

They are also used in high-end designer pieces that focus on storytelling and individuality.

Vintage-inspired engagement rings
Artistic or minimalist designs
