What Is Aquamarine?
Aquamarine is a gemstone from the beryl family, known for its calming blue to blue-green hues. Its name means "water of the sea," which perfectly describes its soft, ocean-like color. Aquamarine’s color comes from traces of iron in the crystal structure.

- Blue topaz colors range from pale sky blue to deep Swiss blue and London blue.
- The most common blue topaz colors are Swiss blue (bright medium blue) and London blue (dark, intense blue).

How Lighting Affects Their Colors
Lighting can change how you see the colors of aquamarine and blue topaz. Both stones react differently under various light sources:
- Aquamarine: Looks best in natural daylight, where its soft blue-green hues shine. Under artificial light, it may appear paler or slightly washed out.

When shopping, view these stones in different lights to see which color appeals to you most.
Durability and Color Stability
Both aquamarine and blue topaz are durable enough for everyday jewelry, but their color stability differs:
- Aquamarine: Has good hardness (7.5-8 on Mohs scale) and retains its color well over time without fading.
- Blue Topaz: Slightly softer (8 on Mohs scale) and its color, especially if treated, can fade with prolonged exposure to strong sunlight.
If you want a gemstone with lasting color, aquamarine is a safer bet. Blue topaz requires a bit more care to keep its vibrant blue.
Price Differences Based on Color
Color plays a big role in the price of both aquamarine and blue topaz:
- Aquamarine: The clearer and more intense the blue, the higher the price. Deep blue aquamarines are rarer and more valuable.
- Blue Topaz: Generally more affordable, even in vivid colors. London blue topaz tends to be pricier than Swiss blue due to its deeper color.
If budget is a concern, blue topaz offers beautiful blue shades at a lower cost. For a more exclusive look, aquamarine’s natural hues can command higher prices.

- Style Preference: Aquamarine’s soft blue suits classic, understated jewelry. Blue topaz’s bright blue fits bold, modern designs.
