It’s not surprising that Blue Sapphires have quickly gained in popularity for engagement rings. Sapphires are a great alternative to diamonds, considering their durability. They give the wearer a unique ring that stands out from the crowd.

To make the process of purchasing a Blue Sapphire just that much easier, we’ve compiled a list of tips to get you the most beautiful sapphire possible.

Color is #1

Color is the most important aspect of a Sapphire, since that is what will first catch the eye. Sapphires don’t only come in blue but pink, purple, orange, yellow, green, colorless and black. Blue remains the most popular and is the color most people associate with a sapphire.

The most highly valued Blue Sapphires range from a Velvety Blue to a Violet Blue. Use judgment when looking at a Sapphire’s color because many people have different preferences on color so it depends on what looks best to the viewer. Just make sure the color is vibrant and not uneven face up.


It is unlikely to find Sapphires without any inclusions. When looking for a Sapphire make sure the stone faces up without any obvious inclusions.

AAA to A Quality

Sapphires, as well as other gemstones are separated into .

AAA: top 10% of natural Sapphires available. They are a medium blue color and are slightly included.

AA: top 20%-30% of natural Sapphires. They are a medium blue color and are moderately to slightly included.

A: 50%-75% of natural Sapphires. They are a dark blue color and look opaque.

When choosing a quality of Blue Sapphire for an engagement ring AAA-AA is suggested.


Sapphires do not have a standardized cut like a diamond does, so it’s important to look at a Sapphire’s cut for its symmetry and sparkle.

The most common shapes a Sapphire is cut into is oval, rounds and cushions. They are cut into many other shapes, but they are usually harder to acquire.


Sapphires as well as other gemstones are measured in millimeters, whereas diamonds are measured in carats. Since Sapphires are usually heavier gemstones a 1 carat Sapphire will look smaller than a 1 carat diamond. To ensure you are getting the size you want relate the millimeter of the Sapphire to a diamonds millimeter. For example, a 1 carat Sapphire is 6mm as it relates to a diamond.

 Lab Sapphires

Lab created Sapphires are a great alternative to a natural Sapphire. They are made with the same physical properties of a natural Sapphire and there is no visual difference. The main difference is the affordability of a lab created Sapphire versus a natural. A natural AAA Blue Sapphire is about $2500 versus a lab created Blue Sapphire which is about $400.
