Have you heard of a galaxy diamond before?

Looking at a galaxy diamond is like looking into a clear night’s sky with hundreds of twinkling stars floating in the dark metallic depths of a stone.


Keep reading to learn more about this unique diamond and why it’s a favorite alternative engagement ring style in Portland and beyond.


What is a galaxy diamond?

A galaxy diamonds are gray diamonds that fit a few specific characteristics:

  • A diamond filled with inclusions (specks) that are black or white

  • Darker in color, sometimes with an inky, metallic blue hue

  • Full cut or rose cut diamond

This starry night diamond offers a mysterious, yet enchanting vibe that is difficult not to love. It definitely makes a one-of-a-kind statement and is popular among couples who prefer an alternative engagement ring style.


What’s the difference between galaxy diamonds and salt and pepper diamonds?

Think of it this way — all galaxy diamonds are salt and pepper diamonds, but not all salt and pepper diamonds are galaxy diamonds. 

Both salt and pepper diamonds and galaxy diamonds are filled with a mix of many black and white inclusions. These inclusions affect the diamonds overall appearance, giving it a unique speckled look.

Included in this group of diamonds are those that appear darker, more metallic than the others. These diamonds often look black or blue, and have what can only be described as a spacey, celestial appearance.

Additionally, while salt and pepper diamonds are most always rose-cut, it’s more common for a galaxy diamond to come in a full cut shape.


Is a galaxy diamond a real diamond?

Yes. Galaxy diamonds are genuine, earth-mined, untreated natural diamonds. 

This starry night diamond is formed as it comes into contact with increased levels of hydrogen or baron during its formation period. The interaction with these elements causes the structure and color of the stone to change, producing different hues in the stone. 

Additionally, the extreme pressure and heat the stone experiences during formation is what creates all the little inclusions in the stone (which give it the speckled, starry look).


How rare are galaxy diamonds?

Gray and salt and pepper diamonds are a colorful diamond, so they are considered very rare. As we learned earlier, not every salt and pepper diamond will have that inky, metallic diamond look, making galaxy diamonds even more uncommon

Because of their rarity, many people assume that galaxy diamonds are very expensive. In reality, many galaxy diamonds are more affordable than a traditional white diamond. That’s because galaxy diamonds remain relatively unknown, making the overall demand pretty low. 

However, the popularity of galaxy salt and pepper rings is growing. Now is a great time to invest in one of these alternative rings before they appreciate.


Are galaxy diamonds as good as white diamonds?

Any diamond that you fall in love with is just as “good” (if not better) than any other diamond. 

To some, galaxy diamonds come with more character than a highly sought flawless white diamond. In many ways, these diamonds are even better than a white diamond because they offer a modern take on the traditional engagement ring.  

However, salt and pepper galaxy diamonds are filled with inclusions, which technically makes them weaker than a clear white diamond. That said, galaxy diamonds are still much stronger than your strongest gemstones. 

When you buy a galaxy engagement ring (or any diamond ring), work with a jeweler who is reputable and will provide the highest quality diamonds and rings. Additionally, always insure the ring to cover accidents like theft, loss, scratches, or breaks. 


Where to buy galaxy diamonds

Salt and pepper galaxy diamonds are becoming quite common on sites like Etsy and other online marketplaces. But unless you can confirm a couple important criteria (see below), there are a lot of problems with buying a galaxy diamond from a non-reputable source like this. 



The Gemological Institute of America (or GIA) is a non-profit institute focused on gemology education and research. A GIA certified gemologist has gone through extensive full-time study and hand-on training. They can offer an expert perspective on any questions you have



We don’t mean “guarantee” in the traditional sense, but the seller should make you feel confident in your purchase. For example, we always recommend buying a galaxy ring from someone who can provide ring appraisals, complimentary resizing, and lifetime ring care. Additionally, choose a seller who has credibility. Look for great reviews, information about how long the jeweler has been in business, and active social media accounts. 

Meeting these criteria is almost always impossible for an online marketplace. Instead, we always recommend working with a reputable jewelry company to buy your galaxy ring.


Gray diamond, salt and pepper diamond, or galaxy diamond? Which should you choose?

With gray, salt and pepper, and galaxy rings all being similar, how do you choose which style is right for you? And from there, still more decisions to make:

  • Which specific diamond is your favorite? 

  • Do you want a designer or custom-made ring?

  • What setting do you want?

  • One ring or stackable rings?

It seems like a lot to figure out and answer (and in a way, it is!). But when you work with a reputable jeweler, they walk you through the whole process and make it easy and enjoyable. 

Often, the best way to know which ring is right for you is to see, touch, and try them on in person. The saying is true — when you know, you know!
