Blue Gemstones! When you look at a picture of Earth taken from space, what do you see?
Rich, vibrant blue.
A blue planet! Not only are the oceans blue, but so is the sky.
That’s one of the reasons that blue is so universal.

There’s something comforting and accessible about the color blue.
On the color spectrum, it’s such a nice medium between various bold hues.
Yet blue often has the advantage of shimmering and reflecting light beautifully.
It can often speak of mystery and infinity.
These are some clues as to why blue has been such a popular color for gemstones, not only for generations, but very much at the present moment, too.

With all the versatility of blue, with the way it matches so many outfits and accessories, it’s hard to find someone without some blue gemstones in their jewelry boxes.
There are an incredible number of gemstones that are true blue, loyal-royal blue, blue as in Bluetooth, etc.
We will highlight our 12 favorites.
1. Blue Sapphire
Curved trillion pear shaped sapphire diamond ring
There’s no question that Sapphire has been all the rage for quite some time now.
But why? One reason is probably the boldness of the color.
When gemologists (not to mention everyday jewelry fans) rate stone, they look at hue, tone, and saturation.

Saturation can be thought of as the intensity of a color, what makes it vivid.
Sapphire is very highly saturated, and that’s how the stone avoids any murky or gray characteristics.
It also avoids looking too dark in a way that seems to be sucking color in.
Instead, Sapphire is all about throwing color out into the world.
Sapphire gemstones have, in their composition, titanium and iron, and this is where they get their sparkling blue and violet hue.
This makes them elegant.
What’s more, as elegant as Blue Sapphire is, you can actually wear it regularly.
Why? Because it has a hardness score of 9 (10 being the highest).
You aren’t going to find many 9s out there, and gems around 7 are considered extremely resilient.

Sapphire is the birthstone for September and also the anniversary stone for many wedding anniversaries.
There’s no much to not love about this world-class gemstone.
2. Blue Gemstones: Aquamarine

This gemstone is a variety of beryl.

In fact, it recently won the distinction of being named the birth stone for August.
Why is it so popular, and popular recently?
It’s hard to say, but it’s important to understand that blue spinel is completely natural—the blue color does not and cannot come from artificial processes.

Spinel achieves a hardness score of 8, and that’s why it’s so appropriate for everyday use.

It should be appreciated, though, that many blue diamonds have a secondary hue, which can influence their overall color toward blue-gray or even aquamarine tones.
To get a sense of how sought after Blue Diamonds are, and how valuable, here are a few recent events.
In 2014, Sotheby’s in New York auctioned a Fancy Vivid Blue Diamond for $32.6 million.
Because the stone was 9.75 karat, this amounts to $3.4 M per karat.
The buyer, Joseph Lau, bought it for his daughter Zoe, and nicknamed it the Zoe Diamond.
