Blue is one of the popular colors in gemstones. This stunning color signifies wisdom, good fortune, virtue, and holiness. You can have different options when it comes to blue gemstones and the best options among them are blue sapphires and blue diamonds. Both of these gemstones are known for their stunning hue and shine. They can create a vibrant and unique choice for your engagement rings.

But if you are wondering whether to get blue sapphires or blue diamonds, then read along to find out which can be the perfect option for you:


Despite their blue color, both blue diamond and blue sapphires greatly vary in terms of their composition. Blue diamonds are made of pure carbon atoms and there can be slight traces of boron in them which adds the blue color.

Blue sapphires have aluminum oxide or corundum, and the blue color is given by slight amounts of titanium.


Both blue diamonds and blue sapphires can immensely vary in terms of their shades and intensity of color. The intensity can range from faint to intense. Therefore, it is possible for you to get these stones based on the intensity of color you want.

Additionally, both of these gemstones can come with some secondary colors like green, purple, etc. But unlike blue diamonds, sapphire stones that come with a secondary color cannot be called blue sapphires, they will be given other names based on the type of secondary hue present in them.

Rarity And Price

Sapphires are more heavily mined than diamonds, hence, their price can be lower than blue diamonds. But sapphires with intense blue color and high quality can be rare and they can be very costly too.

Blue diamonds are extremely rare in comparison with blue sapphires. Therefore, they come at huge price ranges. But you can get blue lab grown diamonds at more affordable rates in comparison with natural ones.


Diamonds are the most durable gemstones which score a 10 on the Mohs scale. But sapphires are very durable too, as they score 9. Hence, both of these gemstones can be suitable for everyday wear.

One of the important factors that differentiate blue diamonds and blue sapphires is their fire and brilliance. As diamonds reflect and refract more light than sapphires, they can have a more dazzling appearance than the latter.

Even though blue sapphires also shine well, their ability to refract light is inferior to diamonds.

Therefore, when choosing between blue sapphires and blue diamonds, consider your budget and the brilliance you want. Both of these stones can be a wonderful addition to your engagement rings.
