Aquamarine, with its mesmerizing blue hues reminiscent of the ocean, is a favorite among gemstone enthusiasts. The cushion cut, known for its soft, rounded edges and brilliant facets, adds a timeless elegance to this stone. Choosing the best cushion cut aquamarine, however, requires more than just an appreciation for its beauty. It involves understanding the nuances of the gemstone’s characteristics, from color and clarity to cut and carat weight. This guide will walk you through the essential factors to consider when selecting the perfect cushion cut aquamarine.
Understanding Aquamarine: The Basics
What is Aquamarine?
Aquamarine is a variety of the mineral beryl, which also includes emerald and morganite. Its name comes from the Latin words “aqua” (water) and “marina” (sea), reflecting its stunning blue-green color. The gemstone is often associated with tranquility, courage, and clear communication, making it a popular choice for jewelry, particularly for those born in March, as it is the month’s birthstone.
Why Choose a Cushion Cut?
The cushion cut, also known as a “pillow cut,” has been popular for centuries and is characterized by its square or rectangular shape with rounded corners. This cut combines the brilliance of a round cut with the chic shape of a square, offering a vintage yet versatile look. Cushion cuts are known for their ability to enhance the color and brilliance of a gemstone, making them an excellent choice for aquamarine, which often has delicate hues.
Key Factors to Consider When Choosing a Cushion Cut Aquamarine
1. Color: The Heart of the Gemstone
Color is one of the most important aspects of any gemstone, and aquamarine is no exception. The best cushion cut aquamarines exhibit a clear, intense blue color, often with a hint of green. The color of an aquamarine can range from pale, almost colorless blue to deep blue-green. When choosing a cushion cut aquamarine, look for the following:
Hue: The hue refers to the basic color of the stone. For aquamarine, the ideal hue is a pure blue to slightly greenish-blue. Stones with a more greenish tint may be less valuable, although some people prefer this unique variation.
Tone: The tone refers to the lightness or darkness of the color. Aquamarines typically range from very light to moderately dark. The best cushion cut aquamarines have a medium tone, which offers a balance between brightness and color saturation.
Saturation: This refers to the intensity of the color. Highly saturated aquamarines with vivid blue colors are considered the most valuable. However, overly dark or murky stones can appear less vibrant, so it’s essential to find a balance.
2. Clarity: The Window to Quality
Clarity describes the presence of inclusions or blemishes within the gemstone. Aquamarines are generally known for their high clarity, with very few visible inclusions. When choosing a cushion cut aquamarine, clarity is crucial because inclusions can be more noticeable in light-colored stones.
Eye-Clean: The best aquamarines are “eye-clean,” meaning they have no visible inclusions to the naked eye. Inspect the stone carefully in different lighting conditions to ensure it is free from inclusions that could impact its beauty.
Inclusions: If inclusions are present, they should be minimal and located in areas where they are less visible, such as near the edges. Avoid stones with large or dark inclusions that can detract from the gemstone’s appearance.
3. Cut: Maximizing the Gem’s Beauty
The cut of the aquamarine refers to how well the gemstone has been shaped and faceted. The cushion cut is particularly well-suited to aquamarine because it enhances the stone’s natural brilliance and color. A well-cut cushion aquamarine will reflect light evenly across its surface, creating a stunning, sparkling effect.
Proportions: The proportions of the cushion cut are crucial. The stone should have a good balance between its length and width, typically with a length-to-width ratio between 1.00 and 1.20. The depth of the stone should be sufficient to allow light to reflect internally, enhancing its brilliance.
Symmetry: Symmetry is essential in a cushion cut. The facets should be perfectly aligned, and the stone should be symmetrical from all angles. Poor symmetry can result in uneven light reflection and a less attractive gemstone.
Polish: The surface of the gemstone should be well-polished, free from any scratches or marks. A high-quality polish enhances the stone’s luster and overall appearance.
4. Carat Weight: Balancing Size and Quality
Carat weight is a measure of the gemstone’s size. While larger aquamarines can be impressive, it’s important to balance size with quality. A larger stone with poor color or clarity may not be as desirable as a smaller, higher-quality stone.
Size Preferences: Consider your personal preferences and how you plan to wear the gemstone. For a ring, a larger cushion cut aquamarine might be ideal, while for earrings or a pendant, a slightly smaller stone might be more appropriate.
Weight vs. Dimensions: Remember that carat weight does not always equate to size. Some stones may have more depth, making them heavier without appearing larger. Focus on the stone’s dimensions (length, width, and depth) rather than just its weight.

Additional Considerations for Cushion Cut Aquamarine
1. Setting: Complementing the Stone
The setting of your aquamarine gemstone can significantly impact its appearance. The cushion cut works well with a variety of settings, from classic solitaire to more elaborate halo designs. When choosing a setting, consider the following:
Metal Type: White gold and platinum are popular choices for aquamarine, as their cool tones complement the stone’s blue hues. Yellow gold can add a warm contrast, creating a unique look.
Prong vs. Bezel: Prong settings allow more light to enter the stone, enhancing its brilliance, while bezel settings provide more protection but can reduce light reflection. Choose a setting that balances security with showcasing the stone’s beauty.
Halo Settings: A halo of smaller diamonds around the cushion cut aquamarine can enhance its size and brilliance, making the stone appear larger and more dazzling.
2. Certification: Ensuring Authenticity
Always purchase a cushion cut aquamarine with a certification from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the American Gem Society (AGS). A certificate provides essential information about the gemstone’s characteristics, including color, clarity, cut, and carat weight. It also confirms that the stone is natural and has not been treated in ways that could affect its value.
3. Budget: Finding the Right Balance
Aquamarine is a relatively affordable gemstone compared to others like diamonds or sapphires, but prices can vary based on quality. Determine your budget beforehand and prioritize the factors that matter most to you, whether it’s color, clarity, or size. Remember, a well-chosen aquamarine can offer exceptional beauty at a reasonable price.
Conclusion
Selecting the best cushion cut aquamarine involves a careful balance of color, clarity, cut, and carat weight, along with considerations for the setting and certification. By understanding these key factors, you can choose a gemstone that not only meets your aesthetic preferences but also offers lasting value. Whether you’re selecting a stone for an engagement ring, a pendant, or a special piece of jewelry, a well-chosen cushion cut aquamarine will captivate with its ocean-like beauty and timeless elegance.
