When it comes to choosing a diamond, someone who does not know much about diamond grading might think that obviously, a bigger diamond is a better one. But, in fact, this is not always true at all! Let us take a look.
The Four Cs
Diamond novices will quickly learn about the four cs of diamond buying, which are: clarity, color, carat, and cut, and refer, respectively to the see-through qualities of the diamond, whether it has any hint of color to it, the size, and the shape it has been cut into. It is all of these factors that decide if a diamond is of good quality, not merely the size of it. And, in fact, the size can sometimes be the least important quality of a diamond!
From this, you will deduce that the answer to the question asked by the title is that a high-quality diamond is better, and this is, in fact, usually true. The factor that marks a diamond as being better than another is usually the clarity, followed closely by the color.
What are Clarity and Color?
Clarity and color are often confusing when it comes to diamonds because the color needs to be colorless, or as close to colorless as possible*, while clarity refers to how translucent the diamond is. To newcomers to the diamond world, this can sound like the same thing! But clarity or ‘ see-throughness ‘ is caused by the diamond’s inner integrity. Flaws, fractures, imperfections, and contamination within the stone all affect the clarity, preventing light from flowing and reflecting into, through, and out of the stone in the way that makes a diamond sparkle so beautifully.
*While color is ideally as colorless as possible, there is also a market for colorful diamonds, in which various elements have interacted with the carbon while the diamond was forming, many miles beneath the earth’s surface and billions of years ago, creating diamonds that have distinct colors, ranging from yellow to red to green and blue, and in hues ranging from the merest hint of color to deep vivid shades that could see the diamonds mistaken for other precious stones.
The Cut is the Deepest
But it is the cut of the stone that often determines its value. A poorly cut stone will not sparkle, could contain fractures and flaws that weaken it, and will generally look unsightly, especially in the company of well-cut diamonds! A good diamond cut will remove as many inclusions and flaws as possible, leaving as clear a stone as can be managed, and will aim to direct the flow of light into the stone from all sides, but only release it through the table – or top facet – of the stone, enhancing that evocative diamond sparkle, such as seen in these stones at www.whiteflash.com/loose-diamonds/search/.
It is only after these three aspects: cut, clarity, and color, have been assessed that the size of the stone will be taken into account for valuation. And it is true to say when comparing two stones of equally good cut and comparable color and clarity then size really does matter!
