Aquamarine: what kind of stone it is and why it's chosen for silver jewelry
Briefly: Aquamarine is a variety of beryl with a blue color from iron impurities; the largest deposits are in Brazil. Its hardness of 7.5-8 on the Mohs scale allows for everyday wear, but it should be stored separately from harder stones. The cool blue tone harmonizes best with 925 silver, which allows the stone to remain the star without drawing attention away from it.
Aquamarine is a variety of the mineral beryl with a blue or blue-green color. The color comes from iron impurities. The name comes from the Latin "aqua marina," meaning seawater. The name is accurate: good aquamarine truly resembles the color of shallow sea on a sunny day.
Where it is Mined
The largest deposits are in Brazil. Most large stones with saturated color come from there. There are also deposits in Pakistan, India, and Africa.
Indian aquamarine often has natural iridescence — a play of light within the stone. This is not a defect; it's an effect of inclusions. This is the type used in jewelry from the Ocean Muse collection by SIERRA SPACE.
Hardness and Wear
7.5-8 on the Mohs scale. Suitable for everyday wear, but less resistant to scratches than moissanite or corundum. Store separately from harder stones.
Why Aquamarine Looks Good with Silver
The cool blue tone of the stone and the white metal of silver complement each other without competing. Gold — especially yellow — draws attention to itself. 925 silver allows the stone to remain the focal point.
There's also a practical side to this: aquamarine is usually not very dark, so white metal allows it to "breathe," while yellow can make the stone appear duller than it is. View aquamarine jewelry in the Ocean Muse collection.
Natural or Lab-Grown
Lab-grown aquamarine exists but is rarely used in jewelry — natural aquamarine is not overly expensive itself. If a seller is selling "aquamarine" at a suspiciously low price and the stone is perfectly clean without any inclusions, it might be synthetic or even glass.
Good natural aquamarine has minor inclusions. Absolute transparency is rare and priced accordingly.
Frequently Asked Questions
Does aquamarine change color in the sun?
It can fade slightly with prolonged direct exposure to the sun. Do not store it on a windowsill.
Are aquamarine and blue topaz the same color?
Similar, but not identical. Topaz is often more saturated and uniform. Aquamarine usually has a softer shade with a slight greenish tint. The difference is noticeable when they are side by side.
How to clean aquamarine?
Warm water with mild soap and a soft brush. Use ultrasonics only if there are no inclusions or cracks. Avoid any harsh chemical cleaners.
