Aquamarine is one of the most beloved gemstones in the world, known for its serene ocean-blue color and exceptional clarity. As the birthstone for March, aquamarine has long been associated with calm seas, clarity, and timeless elegance. Whether you are shopping for an aquamarine ring, pendant, earrings, or bracelet, understanding what makes a high-quality aquamarine gemstone can help you make a confident purchase.
In this aquamarine buying guide, we will walk through the most important aquamarine buying tips, including color, clarity, cut, and carat weight, so you know exactly what to look for when selecting the perfect aquamarine jewelry piece.
Aquamarine belongs to the beryl gemstone family, which also includes emerald and morganite. Its name comes from the Latin words aqua marina, meaning “water of the sea,” a perfect description of its tranquil blue color.
High-quality aquamarine gemstones are prized for their crystal clarity and soft blue hues that range from pale sky blue to deep ocean blue.
Popular aquamarine jewelry styles include:
Aquamarine engagement rings
Aquamarine pendant necklaces
Aquamarine stud earrings
Aquamarine tennis bracelets
Aquamarine cocktail rings
Because aquamarine is both durable and elegant, it is an excellent gemstone for everyday wear.
When buying aquamarine, color is the most important quality factor.
The finest aquamarine gemstones display:
A pure blue color
Slightly greenish-blue undertones
Strong, even saturation
Deeper blue aquamarines tend to be more valuable than lighter stones. However, many people love the airy, light-blue aquamarine shades that resemble tropical waters.
Look for a gemstone with even color throughout the stone.
Avoid stones that appear too pale or washed out.
Medium to medium-dark blue aquamarine typically offers the best balance of color and brilliance.
Because aquamarine is naturally lighter in color than sapphires, larger stones often display more noticeable color.
One of the most attractive features of aquamarine gemstones is their exceptional clarity.
Unlike emeralds, which commonly have inclusions, aquamarines are usually eye-clean, meaning you cannot see internal imperfections without magnification.
Look for eye-clean stones with high transparency.
Avoid stones with visible inclusions or cloudy areas.
Clear aquamarine stones allow more light to pass through, creating beautiful sparkle and brilliance.
High clarity is one reason aquamarine gemstones look so luminous in rings and pendants.
The cut of an aquamarine gemstone greatly affects how much it sparkles.
A well-cut aquamarine reflects light evenly and enhances the stone’s natural color.
Common aquamarine cuts include:
Oval cut aquamarine
Emerald cut aquamarine
Cushion cut aquamarine
Round brilliant aquamarine
Pear shaped aquamarine
Choose a gemstone with symmetrical proportions.
Avoid stones that appear too shallow or too deep, which can reduce brilliance.
Look for facets that reflect light evenly across the stone.
The right cut helps bring out aquamarine’s signature glow.
Aquamarine crystals naturally form in large sizes, which means larger aquamarine gemstones are more commoncompared to many other gemstones.
Interestingly, aquamarine color often appears richer in larger stones, which is why aquamarine rings and pendants frequently feature larger center stones.
If you want stronger color, consider larger aquamarine gemstones.
Aquamarine offers excellent value in larger carat weights compared to many gemstones.
Choose a size that complements the jewelry style you prefer.
Large aquamarine cocktail rings and statement pendants are particularly popular because of this.
Most aquamarine gemstones on the market are heat treated, which is a common and accepted practice in the gemstone industry.
Heat treatment removes greenish tones and enhances the gemstone’s beautiful blue color.
This treatment is:
Permanent
Stable
Widely accepted in the jewelry industry
There are typically no durability concerns with heat-treated aquamarine.
Aquamarine gemstones look stunning in many jewelry designs.
Some of the most popular aquamarine jewelry styles include:
Aquamarine engagement rings for a unique alternative to diamonds
Aquamarine pendant necklaces for everyday elegance
Aquamarine earrings for a subtle pop of color
Aquamarine bracelets for refined sparkle
Aquamarine pairs beautifully with diamonds, creating a bright and luxurious look.
Aquamarine ranks 7.5 to 8 on the Mohs hardness scale, making it a durable gemstone suitable for daily wear.
To keep your aquamarine jewelry looking beautiful:
Clean with warm water, mild soap, and a soft brush
Avoid harsh chemicals and ultrasonic cleaners
Store aquamarine pieces separately to prevent scratching
Proper care will keep your aquamarine gemstone sparkling for years.
