Blue Gemstones - What’s the Best One for You?

Jewellery is a classic piece of art. It’s timeless and can outlive generations. Thus, when choosing the stone colour of your jewellery, you should ask yourself, “What colours would you treasure always?”

One of the most timeless colours is blue. In jewellery, this colour is especially mesmerising. It has a wide range of hues in a beautiful intensity. Owning a blue gemstone is a fine investment and a good idea.

Since blue gemstones vary widely, here are the top blue gems that are perfect for jewellery.

1. Blue Sapphire

You can never go wrong in choosing a Blue Sapphire. Its long-known history has always connected with royalty. This iconic gem varies with its deep velvet blue to a mid sky and also slightly violet-blue. With a blue sapphire gemstone being 9 in MoH's scale of hardness you’ll always enjoy a scintillating vivid hue.

2. Blue Aquamarine

Want to have something that reminds you of looking at the ocean? A blue aquamarine gemstone is perfect. It comes in unique light pastel blue. When choosing an Aquamarine look for clarity, and evenness of colour within the stone. Aquamarine is a timeless classic to add to your collection.

3. Blue Tanzanite

A vivid indigo blue, blue tanzanite can captivate you with exceptional colour. It is the property of light splitting into three, you will also find flashes of purple a combination that truly catches the eye.

You should feel very blessed to own tanzanite because this is an extraordinary gemstone to be found only in one small part of the earth, the hills of Tanzania.

4. Blue Spinel

Blue Spinel is a quite rare gemstone that exhibits good hardness. It is generally found in grey blue colours but also occurs pink & red tones. Unlike the other blue gemstones such as Sapphire, Tanzanite and Aquamarine, spinel is not heated to improve the colour.

5. Alexandrite

Often described by gem aficionados as “emerald by day, ruby by night,” Alexandrite is the very rare colour-change variety of the mineral chrysoberyl. It  appears greenish blue in day light and changes to purple under incandescent light. Originally discovered in Russia's Ural Mountains in the 1830s, it's now found in Sri Lanka, Madagascar, India and Brazil, but fine material is exceptionally rare and valuable.

6. Blue Tourmaline

A fascinating rare electric blue tone of tourmaline found in Brazil (Pariaba) and Namibia.

7. Blue Topaz

Blue Topaz is another beautiful blue gemstone. It is available in large sizes and has very few flaws.

Blue Topaz occurs in 3 colours - Sky (light) Swiss (Mid) and London (Dark)

8. Blue Diamond

A blue diamond is incredibly rare and owning and untreated stone is an eternal masterpiece. Blue Diamonds appear as untreated natural gemstones. A 45-carat blue diamond was insured for $250 million.

However, you can look for an enhanced blue diamond. It is exposed to high heat and pressure to turn into a vivid blue gem. It is still expensive but more affordable than the untreated ones.

9. Blue Zircon

Blue Zircon is the most underrated among all the gemstones listed here, fire, brilliance, and clarity. Blue zircons have all undergone traditional hearting to obtain the vivid blue stones. They come in big sizes and are reasonably priced.
