Aquamarine is a stunning blue-green gemstone belonging to the beryl family, which also includes emerald and morganite. Its name comes from the Latin words aqua (water) and marina (sea), perfectly describing its captivating ocean-like hues. With a hardness of 7.5 to 8 on the Mohs scale, aquamarine is durable enough for everyday jewelry while offering exceptional clarity that rivals even the finest gemstones.
What Determines Aquamarine’s Value?
Several key factors influence aquamarine’s worth:
- Color: The most valuable stones display a deep, pure blue without green or gray undertones.
- Clarity: High-quality aquamarines are typically eye-clean with minimal inclusions.
- Cut: Precision cutting enhances brilliance and color saturation.
- Carat Weight: Larger stones are available, but exceptional quality matters more than size.
- Origin: Brazilian aquamarines, especially from Santa Maria mines, are most prized.
Aquamarine Price Ranges: From Affordable to Luxury
Aquamarine prices vary significantly based on quality:
- Low-grade: 10–50 per carat (pale, included)
- Medium-grade: 50–200 per carat (light blue, clean)
- High-grade: 200–1,000+ per carat (vivid blue, flawless)
- Rare collector’s pieces: 1,000–5,000+ per carat (Santa Maria deep blue)
Compared to other blue gemstones like sapphire or tanzanite, aquamarine offers excellent value while maintaining beauty and durability.
Is Aquamarine a Good Investment?
While not as investment-grade as rubies or sapphires, aquamarine has its merits:
- Pros: Large sizes available, increasing designer popularity, durable for long-term wear.
- Cons: Market prices stable (not rapidly appreciating), commonly heat-treated.
For investors, focus on rare, untreated stones with exceptional color. For jewelry lovers, aquamarine offers timeless elegance at accessible prices.
