Timeless Brilliance. Infinite Strength.

Colorless Diamonds — Classic Beauty with a CBQ Twist

There is truth in the enduring beauty of a classic colorless diamond. While much of what we do at Caleb B. Quashen International is rooted in color, rarity, and the unusual, the appeal of a beautifully cut white diamond is impossible to deny.

Natural diamonds form deep within the Earth under extraordinary heat and pressure over immense stretches of time. From those extreme conditions comes one of nature’s hardest and most brilliant materials — a stone that has become synonymous with strength, permanence, and light.

Our approach is to respect everything that makes the colorless diamond a classic while still looking for the details that make an individual stone feel different.

Here you may find familiar diamond material transformed through distinctive cuts, unusual proportions, antique-inspired shapes, visible internal characteristics, or simply a personality that separates one stone from the next.

Some are clean and traditional.

Others are a little stranger.

That is usually where we become interested.

What Is a White Diamond?

“White diamond” and “colorless diamond” are often used to describe diamonds with little to no visible body color. In traditional diamond grading, diamonds closer to the colorless end of the scale are valued for their bright, crisp appearance and their ability to allow the interaction of light and cut to take center stage.

But we have never believed that a diamond can be understood entirely by a grade.

Color is only part of the story.

Cut, transparency, clarity characteristics, proportions, fluorescence, facet arrangement, and even the original shape of the rough can dramatically change how a diamond looks and behaves.

Two diamonds can appear similar on paper and feel completely different when they are actually in your hand.

That difference matters.

The Cut Changes Everything

A diamond’s relationship with light is largely determined by the way it is cut.

Modern brilliant cuts are designed to produce intense light return, sparkle, and flashes of spectral color. Step cuts create longer reflections and a cleaner, more architectural appearance. Antique-inspired cuts often have broader facets, taller crowns, and a slower pattern of light that gives them an entirely different personality.

And then there are the diamonds that do not fit neatly into any category.

Those are often the most interesting.

We regularly work with material whose natural shape, inclusions, proportions, or character suggests something less conventional. Rather than forcing every diamond into the same formula, we believe the material should have a voice in what it ultimately becomes.

Sometimes the right decision is maximizing brilliance.

Sometimes it is preserving an unusual shape.

And sometimes it means designing a cut around the very feature another cutter might have tried to remove.

We do not cut every stone to look like every other stone.

We cut the stone that is in front of us.

Clarity, Character & What Nature Left Behind

Traditional diamond grading places significant emphasis on clarity, and exceptionally clean diamonds can be extraordinary.

But clarity is not the same thing as beauty.

Natural diamonds can contain crystals, clouds, feathers, graining, and other internal characteristics created during their formation. Sometimes these features are nearly invisible. Sometimes they become part of the identity of the stone.

We do not automatically believe individuality needs to be cut away.

A diamond can be included and still have tremendous life. It can fall outside traditional ideas of perfection and still be remarkably beautiful. In certain diamonds, an internal characteristic becomes the very thing that makes the stone impossible to duplicate.

For collectors, designers, and clients looking for something personal, those differences can matter far more than perfection on paper.

Choosing a Loose White Diamond

Selecting a loose white diamond gives you the opportunity to begin with the stone rather than the setting.

You can experience its shape, proportions, facet pattern, brilliance, size, and overall personality first — and then build the finished piece around it.

For one-of-a-kind engagement rings, heirloom pieces, custom rings, and other bespoke jewelry, we believe that can be a far more interesting way to begin.

Find the stone that speaks to you.

Then decide what it should become.

We work with private clients as well as jewelers and designers searching for diamonds for specific projects. If you are looking for a particular size, shape, cutting style, or type of material and do not see it in our current collection, reach out to us.

We are constantly sourcing new material and cutting new stones, and we may be able to help find — or create — what you have in mind.

Selected One Diamond at a Time

We do not believe every diamond needs to look the same.

Our collection of loose white diamonds is selected one stone at a time, with an emphasis on beauty, individuality, and the qualities that become apparent when a diamond is actually experienced rather than reduced to a grading report.

Some make their way into the collection because of exceptional brilliance.

Some because of their shape.

Some because of the way they were cut.

Some because nature left something fascinating inside.

And occasionally, because there is simply something about a diamond that we have not seen before.

The classic colorless diamond may be timeless.

That does not mean it has to be ordinary.

White Diamond Questions

Are white diamonds and colorless diamonds the same thing?

The terms are commonly used interchangeably when discussing diamonds with little or no noticeable body color. The traditional diamond color scale provides a more precise way of describing how much color is present, but a grading letter alone does not tell you everything about how a diamond will actually appear.

What diamond color grades are considered colorless?

Under the GIA color grading system, D, E, and F diamonds are considered colorless. Diamonds farther down the scale may display increasingly noticeable traces of color. That does not automatically make one diamond more beautiful than another — cut, proportions, fluorescence, setting, and personal preference can all influence how color is perceived.

Does diamond clarity affect brilliance?

Not always in the way people expect. Certain inclusions can affect transparency or the movement of light through a diamond, while others may have very little visible impact on its beauty. This is one reason we prefer looking at the actual stone rather than judging it only by the clarity grade printed on a report.

What is the difference between a brilliant cut and a step cut diamond?

Brilliant cuts use facet arrangements designed to create strong light return and sparkle. Step cuts use longer, more linear facets that tend to produce broad flashes of light and a more architectural appearance. Neither is inherently better — they simply interact with light differently.

Can I buy a loose diamond for a custom engagement ring?

Absolutely. In fact, we often prefer starting with the gemstone. Choosing the loose diamond first allows the eventual ring to be designed around its exact dimensions, proportions, shape, and personality rather than trying to make the stone conform to a predetermined setting.

Can CBQ source a diamond that is not currently available on the website?

Yes. We work directly with private clients, jewelers, and designers looking for specific gemstones and diamonds. Our inventory is constantly evolving, and new stones are sourced and cut regularly. If you have a particular size, shape, style, or idea in mind, contact us and tell us what you are trying to find.
