What is a Raw Diamond?
Diamonds are celebrated around the world for their brilliance, symmetry, and timeless allure. But before a diamond dazzles in a meticulously crafted setting, it begins in its most natural and untouched form — as a raw diamond.
Whether you're discovering diamonds for the first time or exploring unique options for an engagement ring or investment piece, understanding what a raw diamond is — and what makes it so special — offers a deeper appreciation for the art and precision behind fine jewelry.
At Greis Jewelers, where the Greisdorf family has blended expertise, artistry, and personalized service for generations, we understand the value in appreciating diamonds at every stage of their journey.
Understanding The Basics: What Is A Raw Diamond?
A raw diamond, also known as a rough diamond or uncut diamond, is a natural gemstone in its original crystalline form as it is found in the earth — before it has been cut, shaped, or polished. These stones are mined from deep beneath the earth’s surface, retaining their organic edges, textured surfaces, and earthy tones.
Unlike the sparkling diamonds seen in engagement rings or fine jewelry pieces, raw diamonds appear more opaque, with a matte or slightly greasy luster. Their shapes can range from cubes and octahedrons to irregular and asymmetrical forms, depending on how they formed geologically over billions of years.
How Do Raw Diamonds Look?
A raw diamond is typically:
-
Opaque to semi-translucent
-
Colorless, yellowish, brownish, or even gray
-
Uneven in shape, often with natural etchings or inclusions
-
Lacking the brilliant sparkle of a cut diamond
Despite their unpolished state, raw diamonds possess a quiet, natural elegance — a kind of understated luxury that speaks to the purity of their origins.
Are Raw Diamonds Real Diamonds?
Yes — raw diamonds are 100% real diamonds. They possess the same chemical composition (carbon atoms arranged in a crystal lattice) and physical properties (incredible hardness, high thermal conductivity) as any cut and polished diamond.
The key difference lies in the finishing process. Polished diamonds undergo extensive cutting and faceting to reveal their fire and brilliance. Raw diamonds, by contrast, are left in their natural state — making them a popular choice for those seeking something unconventional and organically beautiful.
What Are Raw Diamonds Used For?
Jewelry
While traditional fine jewelry typically showcases brilliant-cut stones, raw diamonds are increasingly being used in luxury designs that embrace texture, individuality, and organic charm. At Greis Jewelers, we have noticed a growing interest in bespoke pieces featuring raw diamonds — especially in:
-
Modern engagement rings with a natural twist
-
Statement pendants and earrings that highlight texture over sparkle
-
Mixed-metal settings that pair raw diamonds with warm yellow gold or matte platinum
-
These designs appeal to clients seeking exclusivity, authenticity, and a one-of-a-kind look.
Investment and Collection
Raw diamonds are also collected by connoisseurs and investors. Some choose to purchase them before cutting, while others seek rare, untouched specimens that showcase exceptional crystal formation or unique coloration.
How Can You Tell If a Raw Diamond Is Real?
Identifying raw diamonds can be challenging without proper tools. At Greis Jewelers, our expert staff use specialized equipment to confirm a diamond’s authenticity. In general, here are a few basic indicators used by professionals:
-
Hardness: Diamonds are the hardest natural substance and can scratch almost any other material.
-
Thermal Conductivity: Diamonds disperse heat very efficiently — a key trait used in professional diamond testers.
-
Crystal Structure: Raw diamonds often display specific geometrical formations like cubic or octahedral shapes.
For peace of mind, we always recommend purchasing from a trusted jeweler with the expertise and certifications to ensure what you're buying is a genuine diamond.
Can Raw Diamonds Be Cut and Polished?
Absolutely. Every brilliant-cut diamond began its life as a raw diamond. Through a meticulous process involving planning, laser cutting, and polishing, rough stones are transformed into the glittering centerpieces seen in fine jewelry.
However, not all raw diamonds are suitable for cutting — some may be too included or oddly shaped. At Greis Jewelers, our gemologists evaluate each stone individually, selecting only the most promising specimens for cutting or design.
Are Raw Diamonds Valuable?
Yes — raw diamonds can be highly valuable, though their worth depends on multiple factors, including:
-
Carat weight
-
Color and clarity
-
Shape and crystal integrity
-
Rarity or unique features
Unlike cut diamonds, raw diamonds are evaluated differently since they haven’t been enhanced through faceting. That’s why working with a knowledgeable jeweler is essential in determining the true potential and value of a raw stone.

While salt-and-pepper diamonds are faceted and polished, they retain a raw, earthy feel that appeals to similar audiences.
