Introduction to Mine Cut Diamonds

Definition and Characteristics

Mine cut diamonds are one of the earliest forms of diamond cuts, predating the modern brilliant cut. They are characterized by their squarish or cushion shape, high crown, small table, deep pavilion, and large culet. Unlike modern diamonds, which are precisely cut using advanced technology, mine cut diamonds were crafted by hand, resulting in unique, one-of-a-kind stones. Each mine cut diamond was individually shaped and faceted by skilled artisans, resulting in unique and irregular facets. This hand-cut quality gives mine cut diamonds a distinctive charm that is often lacking in machine-cut modern diamonds.

Key Features

Crown: The crown, or the top portion of the diamond above the girdle, is relatively high and steep.

Table: The table, or the flat top surface of the diamond, is small compared to modern cuts.

Pavilion: The pavilion, or the bottom portion of the diamond below the girdle, is deep, contributing to the diamond’s overall height.

Culet: The culet, or the bottom point of the diamond, is large and often visible to the naked eye. The large culet of a mine cut diamond is one of its most recognizable features. In the past, the culet was intentionally faceted to prevent damage to the diamond’s pointed bottom. This practice has fallen out of favor in modern diamond cutting, but the large culet remains a hallmark of antique mine cut diamonds.

Facet Arrangement: Mine cut diamonds typically have 58 facets, similar to modern brilliant cuts, but the facets are larger and more irregular due to hand cutting. The light performance of a mine cut diamond is different from that of a modern brilliant cut diamond. While modern diamonds are designed to maximize brilliance (white light reflection) and fire (colored light dispersion), mine cut diamonds have a softer, more romantic glow. This unique light performance is part of what makes mine cut diamonds so appealing to those who appreciate vintage jewelry.

The History of Mine Cut Diamonds

Origins in the 18th Century

The history of mine cut diamonds dates back to the 18th century, during a time when diamond cutting was a labor-intensive process performed by skilled craftsmen. The name "mine cut" is believed to be derived from the Brazilian diamond mines that were the primary source of diamonds during this period. The shape and cutting style of mine cut diamonds were influenced by the limitations of the tools and techniques available at the time.

The Evolution of Diamond Cutting

Before the advent of mine cut diamonds, diamond cutting was relatively rudimentary. The earliest diamonds were polished using simple tools, resulting in basic cuts with few facets. The development of the mine cut represented a significant advancement in diamond cutting techniques. Craftsmen began to experiment with different faceting patterns to enhance the diamond’s brilliance and fire, leading to the creation of the mine cut’s distinctive shape.

The Rise of the Industrial Revolution

The Industrial Revolution in the 19th century brought about significant changes in diamond cutting. Advances in technology allowed for more precise cutting techniques, but mine cut diamonds remained popular due to their unique charm. The discovery of diamonds in South Africa in the late 19th century also played a role in the proliferation of mine cut diamonds, as new sources of rough diamonds became available.

Transition to Modern Cuts

By the early 20th century, diamond cutting technology had advanced further, leading to the development of the modern brilliant cut. The brilliant cut, with its emphasis on maximizing brilliance and fire, gradually replaced the mine cut as the preferred diamond shape. However, mine cut diamonds continued to be appreciated for their antique appeal and historical significance.

The Craftsmanship Behind Mine Cut Diamonds

The Cutting Process

The cutting process for mine cut diamonds was labor-intensive and required a high level of skill. Diamond cutters used simple tools, such as bow drills and hand-held cutting wheels, to shape and facet the rough stones. The process began with the cleaving of the rough diamond to remove any imperfections and shape the stone into a more manageable form.


Faceting Techniques

Faceting mine cut diamonds involved creating large, irregular facets to enhance the stone's brilliance and fire. The diamond cutter's goal was to maximize the diamond's visual appeal while retaining as much weight as possible. The facets were often uneven, and the angles varied, resulting in a unique and individual appearance for each diamond.

The Role of the Culet

The large culet in mine cut diamonds served both a practical and aesthetic purpose. Practically, the culet reduced the risk of chipping at the diamond's pointed bottom. Aesthetically, the culet added a distinctive feature to the diamond's overall appearance, contributing to its antique charm. The presence of a visible culet is a key indicator of a true mine cut diamond.

How to Choose a Mine Cut Diamond

Assessing Quality

When choosing a mine cut diamond, it's important to assess the quality of the stone based on several factors:

Cut: While mine cut diamonds are known for their unique and irregular cuts, it's still important to evaluate the overall symmetry and proportions. A well-cut mine diamond will have a pleasing balance of facets and a harmonious shape.

Color: Mine cut diamonds come in a range of colors, from near-colorless to various shades of yellow and brown. Consider your preference for color and how it complements the overall design of the jewelry piece.

Clarity: Due to the hand-cutting process, mine cut diamonds may have inclusions or blemishes. Examine the clarity of the diamond to ensure it meets your standards and that any inclusions do not detract from the stone's beauty.

Carat Weight: Mine cut diamonds are often larger and heavier than modern diamonds due to their deeper pavilions. Consider the carat weight in relation to the size and design of the jewelry piece.

Authenticity and Certification

To ensure the authenticity of a mine cut diamond, consider purchasing from reputable jewelers who specialize in antique and vintage jewelry. Certification from a recognized gemological laboratory can provide additional assurance of the diamond's quality and characteristics. Look for certifications that include detailed information about the diamond's cut, color, clarity, and carat weight.

Setting and Design

The settings used for these diamonds were designed to showcase their distinctive features and enhance their natural beauty. Settings that were popular during the height of the old cut diamond include settings featuring filigree and milgrain and halo designs. Ultimately your personal style and preference will largely impact how your old cut diamond is set, but  whether you prefer a classic, vintage look or a modern, customized design, mine cut diamonds offer versatility and timeless appeal. We suggest that you take the time to explore different options and find a piece that resonates with you. These diamonds can be set in nearly any type of setting, but below are some more traditional settings of the old cut diamond eras. 

One of the most common settings for old mine cut diamonds is the prong setting, which was widely used during the Georgian and Victorian eras. In these periods, jewelers often used claw-like prongs to secure the diamond in place while allowing maximum light to enter the stone from all angles. This setting accentuates the diamond's brilliance and fire, emphasizing the cut's charm and sparkle.

Another prevalent setting is the bezel setting, where the diamond is encircled by a thin metal rim that holds it securely. This setting was favored for its durability and protection, making it a popular choice for rings and other jewelry pieces that were worn daily. The bezel setting also highlights the diamond's shape and cut, providing a vintage aesthetic that complements the old mine cut's antique appeal.

Cluster settings, where multiple smaller stones surround a central old mine cut diamond, were another popular choice. These settings create a dramatic and ornate appearance, enhancing the central diamond's visual impact. Cluster settings were particularly favored in Victorian-era jewelry, adding to the period's romantic and intricate designs.

Caring for Mine Cut Diamonds

Cleaning and Maintenance

Proper cleaning and maintenance are essential to preserving the beauty and integrity of mine cut diamonds. Clean your diamond regularly using a soft brush, mild soap, and warm water. Avoid using harsh chemicals or abrasive materials, as they can damage the diamond and setting. Gently pat the diamond dry with a soft cloth.

Professional Inspections

Have your diamond jewelry professionally inspected and cleaned by a jeweler at least once a year. A professional jeweler can check for any signs of wear or damage, ensure the settings are secure, and perform any necessary repairs. Regular inspections help maintain the longevity and beauty of your diamond.

Safe Storage

When not wearing your mine cut diamond jewelry, store it in a safe and secure place. Use a jewelry box with individual compartments or a soft pouch to prevent scratches and damage. Avoid storing your diamond with other pieces of jewelry, as they can rub against each other and cause wear and tear.
