Sapphires are precious gemstones made of aluminum oxide, a mineral called corundum, second to the diamond’s hardest mineral. Corundum has varieties of variations depending on its intrusions, such as titanium and iron. 

Corundum that contains a trace percent of titanium will appear colorless. With iron as a trace element, it would result in a pale yellow. However, if both elements, titanium, and iron, are present in corundum, it results in a deep blue color, forming your blue sapphires.

Buyer’s Guide: Notable Features to Look for Before Buying Your Blue Sapphires

Type of Use and Style

Some might prefer a lone blue sapphire crystal to keep for their collection or for flexibility in styling or customizing it as an accessory. However, some might simply want to own a blue sapphire crystal that is already set-up as a piece of jewelry to wear like rings, pendants, earrings, etc.

You can also consider what style of cut you want your crystal to have. The most common cuts are the oval, round, and cushion ones. Other unpopular and unconventional ones could be harder to cut and can have limited compatibility with some outfits or occasions.

Carat Weight

The sapphire’s carat would mostly refer to the sapphire crystal’s overall weight. It can give an estimate of your sapphire’s size, but it won’t always be accurate. Usually, the higher the carat weight, the more valuable your gemstone will be. However, it may not always be the case, as your blue sapphire can also vary in value based on its purity, clarity, color, and the like.

Crystal Size

Sapphire crystals can be measured in inches or millimeters running throughout its diameter. They usually range from 6-11mm cuts to be conveniently set into jewelry pieces as an accessory. The larger the sapphire crystal is, the more costly it would be. However, it will also be more captivating, a great accessory for formal events.

Color and Clarity

A clear blue sapphire that is pleasing to the eyes would be highly-priced. Although color preference may be subjective, generally, a cornflower blue is historically given the most appreciation. Most feel that it is the truest and purest blue pleasing to the eyes, sometimes also called the royal blue.

You should invest in your sapphire cut quality because it may seem blue but can appear lifeless and dull if the clarity is compromised due to its cut. A great cut would exhibit maximum brilliance and clarity.


Most sapphire stones that are sold on the market are treated to enhance their clarity. Heating is usually used to dissolve or remove some inclusions that interfere with the blue sapphire crystal’s clarity.

Untreated crystals are rarer, especially if they are naturally blue and clear, making it a greater investment. Treated crystals exhibit maximum clarity, so they are still on demand and valuable as well. Heating treatment effects would have a lasting effect throughout your sapphire’s life.

Durability of Material

Lone sapphire crystals are naturally harder than any other gemstone apart from diamond and its corundum counterparts. However, they can still be ruined with pressure, as toughness is different from hardness. If your blue sapphire is set on some metal material to be used as an accessory, it would be best if they are protected with rims or plating to prevent scratching other gemstones and protect from accidental impacts.

For the metal material attached to your sapphire jewelry accessory, ensure that they have a high-quality metal material to match the elegance of your sapphires. Most jewels would use white or yellow gold metal material added with some protective plating to make them resistant to tarnishing.

Verified Authenticity

It would be smart to purchase gemstones from verified sellers specializing in jewelry for those who plan to buy authentic blue sapphire crystals. Reputable brands and sellers would include a Certificate of Authenticity with your purchase to guarantee your gemstone’s legitimacy.

Good Reviews and Ratings

If you were to be meticulous in choosing your products before buying them, you would read reviews from verified purchasers who’ve already seen the product first-hand. You can assess noteworthy features and what makes your blue sapphire purchase worth your money through their testimonials. 

Within Your Budget

When you compare numerous products in the market, you can assess what features set them apart from the other products. Using the factors named above, you can prioritize the features you find most important to you.

You may sacrifice some negotiable features for your blue sapphire if you have a minimal budget to buy the most extravagant ones in the market today. You may start by selecting the carat, size, and style or the type of use you want it for that would best fit your budget. Then you can ensure the authenticity and wear-resistance and be happy with how it looks on you or your collection overall. 

If you buy sapphire crystals as jewelry, it would be best to invest in its durability and overall design, so you love how it looks on you while making it cost-effective in the long run. The seller should also have satisfaction guarantees, money back, and other warranties that would be useful throughout your sapphire jewelry’s life. 

However, if you plan to invest in a lone-blue sapphire crystal, you would only be limited with features, considering its main properties that make them pretty and valuable, which are carat weight, size, clarity, and color.

FAQs – Frequently Asked Questions 

Is sapphire considered more valuable than diamond?

Traditionally, sapphires were used by the royalties as engagement rings and are usually preferred over diamonds due to their rarity over them. History and its color made sapphires associated with royalty, especially the blue ones. 

As diamonds are considered the hardest mineral and exhibit pure, clear brilliance, they are much more valuable today. However, a sapphire can be considered more valuable if found with exceptional natural untreated clarity and perfect blue color as they are extremely rare.

Why are sapphires blue?

Sapphires can also appear colorless, yellow, green, or pink, depending on what element intrusion is dominant. However, blue is the most common color for sapphires due to the mixture of titanium and iron intrusions in the mineral corundum. With the right mix of titanium and iron, a rich bluer color can be achieved. However, other elements may intrude, or the lack of the elements may exhibit a different color for your corundum, which gives a different color for your sapphire crystal.

How can I tell if my blue sapphire is authentic?

First, you must ensure that you buy your blue sapphire crystal from a trusted seller, especially if it’s online. A reputable seller such as the Blue Nile and James Allen would have a long-running reputation in the industry. They usually offer great deals, good customer service, and gemstone certificates.

If you already have blue sapphire at hand, you can check for inclusions, as natural gemstones would usually exhibit inclusions or some minor imperfections. If you want to be sure, you can have them tested in an accredited lab for other non-intrusive tests that will retain your sapphire’s beauty.

What is considered the rarest sapphire?

The Padparadscha Sapphire is considered the rarest type of gemstone due to its unusual and captivating orange and pink mix. They are unknown to most people but instantly becomes a favorite when discovered. Most appear salmon-colored, but some are not evenly colored and exhibit a color zoned pink and yellow color.
