Zales Cushion-Cut Diamonds
Experience a diamond shape that is abounding in tradition and historical charm. Imagine a diamond that offers exceptional beauty, sparkle, and durability delicately adorning your partner’s features. The pillow-shaped cushion-cut diamond evokes an elegant charm adored by celebrities and royalty alike.
With rounded corners accenting a square or rectangular shape, the proportions of each cushion-cut diamond offer light disparity that radiates a kaleidoscope of beautiful colors.
The classic cushion-cut diamond has been used in unique fine jewelry pieces for nearly 200 years. Until the early 20th century when round-cut diamonds took over, the cushion-cut was by far the most popular diamond shape.
As the name may suggest, the cushion-cut diamond is a square or rectangular diamond shape that resembles a pillow. Traditionally, cushion-cut diamonds feature a square shape with rounded corners. However, the most popular cushion-cut diamonds are those with a slightly rectangular shape bearing a 1.10 to 1.20 length-to-width ratio.
Originally, miners in Brazil first found what would become the cushion-cut shape. After similar diamonds were found in South African mines, this cut became known as the “Old Mine-cut” after the Brazilian diamond mines that shared the name. The popular modern cushion-cut diamond is sometimes described as a cross between the Old Mine-cut and a modern oval shape.
As with all diamonds, your personal taste is most important when it comes to choosing the exact shape of the diamond cut.
Do Cushion-Cut Diamonds Sparkle?
The cushion-cut diamond is made up of between 58 (traditional) and 64 (modern) facets respectively. The cushion-cut also features fantastic scintillation or flashes of visible light. This translates to a distinctive, cushion-cut sparkle.
Although they are generally not as brilliant as round-cut diamonds, cushion-cut diamonds do have larger facets that allow for greater dispersion in which white light is separated into spectral colors.
Originally cut with the intention of reflecting the flickering flames of candlelight, people love the cushion-cut for its capability of dispersing natural light and reflecting spectral colors back in a captivating rainbow of colors. For this reason, it was originally known as the “Candlelight-Cut Diamond”, though that style is now considered an “antique cut”.
Throughout the long history of the cushion-cut diamond, techniques and cutting styles have evolved greatly. As such, several variations of the cushion-cut exist, including:
- Standard Cushion Brilliant-Cut: features faceting arrangements that are very similar to Round Brilliant-cut diamonds, leading to higher brilliance.
- Modified Cushion Brilliant-Cut: a variation of the standard cushion-cut with an added row of facets that lie below the girdle. This style has a wonderful sparkle and tends toward a more “crushed ice” diamond look. Modified Cushion Brilliant-Cut diamonds tend to be less expensive than their standard counterparts.
- Crushed Ice Cushion-Cut: when viewed from above, this style does not have an easily discernible facet pattern. This diamond style is often referred to as having a “broken glass” look. When exposed to light, the Crushed Ice Cushion-Cut gives off a wonderful sparkle similar to a radiant-cut diamond.
- Chunky Cushion-Cut: when viewed from the top, this diamond cut features a clearly-defined facet pattern. These appear similar to round brilliant diamonds, and are sometimes referred to as “Antique Cushion-Cuts”.
Cushion-cut diamonds have a distinctive look especially prized by those who appreciate fine jewelry with a vintage flair.
Grading System of Zales Cushion-Cut Diamonds
At Zales, we rely on the trusted experts at GS Laboratories (GSL) to grade our precious stones.
Incorporated in 1985, GSL functions as an independent laboratory for unbiased, professional diamond grading. GSL inspects each diamond under closely controlled lighting and viewing conditions to determine diamond grades. Their trained grading professionals use highly-calibrated measurement devices to capture important data for use in determining the square diamond’s quality. The experts at GSL grade our cushion-cut diamonds on the following determinations:
The weight of the diamond is measured using the carat system. GSL uses specialized scales to ensure an accurate weight measurement – the weights are measured to the hundred-thousandths of a carat. With the carat system, one metric carat is equal to 0.2 gram. That's why expert measurements and calibrated tools matter so much when it comes to determining diamond quality.
Cushion-cut diamond clarity refers to the appearance of the stone, and it notes any blemishes or inclusions. The GSL grades square diamond clarity as one of six grades – Flawless, Internally Flawless, Very Very Small Inclusions, Very Small Inclusions, Small Inclusions, or Imperfect.
When looking at diamonds, much of the decision process may seem subjective. Many blemishes may only be visible to a professional with highly-specialized equipment. As such, when evaluating the clarity of a diamond, one of the most important factors is whether or not the diamond appears to be clear to the human eye. Some buyers may prefer to know that their princess diamond is certified as flawless while others may not mind minor blemishes invisible to the naked eye.
If your partner prefers a more flawless appearance for their diamond jewelry, you’ll want to choose a Flawless or Internally Flawless diamond. If small imperfections do not stand out to your partner, then a Very Small Inclusions or Small Inclusions grade may be preferred.
Using the GSL ratings for clarity can help you to understand your preferences for cushion-cut diamond clarity.
The industry standard for grading cushion-cut diamond color is a system that begins with a D grade (colorless) and continues with increasing levels of color to a Z grade.
Diamonds are compared to master stones with known color grades. In fact, GSL utilizes master stone sets that are chosen based on rigorous standards then tested prior to use.
To the naked eye, diamond color is closely tied to the size of the cushion-cut diamond and the setting. Small differences in diamond color are difficult to see for the human eye, but they may account for a large difference in the price of the diamond. Additionally, the setting color and material chosen for the cushion-cut diamond can make an immense difference in the color of the diamond. Ideally, a diamond should always look colorless against its setting, so keep in mind what the setting will look like when shopping for diamond color.
Cushion-cut diamonds tend to retain their natural color better than other diamond cuts, making them a popular choice of cut for colored diamonds in jewelry.
The proportions of a cushion-cut diamond determine how brilliantly the diamond will shine. Grading of a diamond’s cut is determined by examining its angles, facets, and polish. Overall, the goal of attaining a good cut of diamond is to create a diamond that has the correct proportions to allow the maximum amount of light to travel through it. This will give the diamond a beautiful sparkle that your partner will love.
As we saw above, many variations of the cushion-cut exist -- each with unique cut features. The cushion-cut can range from having large, clearly defined facets to having a “crushed ice” look with no clearly discernible facet pattern.
It is important to consider that personal preferences will play an important role when deciding between these variations, as each variety will give off a unique type of sparkle.
Each diamond is given one of the following grades for cut: Ideal, Excellent, Very Good, Good, Medium, Fair, or Poor. A high-quality diamond cut will feature proportions that allow optimal light reflection through the crown and table, giving off a beautiful, brilliant sparkle.
