When it comes to engagement rings, there are a lot of choices to make. But one of the most important decisions is what kind of center stone to choose.

Some couples opt for a traditional diamond, while others might choose a white sapphire instead.

Though both gemstones are white, diamonds are more sparkly and have a higher refractive index. Sapphires, on the other hand, are less shiny and have a lower refractive index, but are much more affordable.

So which is the better option? Here’s what you need to know.

What’s the Difference Between a White Sapphire and Diamond?

While both diamonds and white sapphires are beautiful choices for jewelry, there are some key differences between them.

For one thing, diamonds are much harder than white sapphires, making them more durable. They also tend to be more expensive, although this can vary depending on the specific stone.

Here are the main factors to consider when comparing white sapphire vs diamond center stones:


Sapphires are one of the hardest minerals on Earth, ranking 9 on the Mohs Scale of hardness. This means that sapphires are resistant to scratching and wear, making them an excellent choice for jewelry.

White sapphires, in particular, are known for their durability and purity. Because they lack impurities, white sapphires tend to be harder than other colors of sapphire. As a result, they are less likely to scratch or chip. In addition, white sapphires are highly resistant to heat and chemicals.

For these reasons, white sapphires are often used in settings that require a durable stone, such as watches or engagement rings. Sapphires of all colors are prized for their strength and beauty, but white sapphires are especially valued for their durability.

Though they are often associated with luxury and wealth, diamonds are actually quite durable. In fact, they are the hardest natural material on Earth.

Diamonds are made up of carbon atoms that are arranged in a lattice structure. This unique arrangement gives diamonds their extraordinary hardness. However, it also makes them susceptible to damage from extreme heat or pressure.

For example, if a diamond is hit with a hammer, it may chip along the edges. But if it’s simply scratched with a metal file, it will show no signs of wear.

In general, diamonds are very resistant to scratching and chipping, but they can be damaged if subjected to too much force. So, while diamonds may be beautiful and valuable, they’re not indestructible.


When it comes to choosing a precious stone for an engagement ring or other piece of jewelry, many people narrow their search down to diamonds. However, diamonds are not the only option when it comes to white gemstones.

White sapphires are also a popular choice, and they offer a number of advantages over diamonds. For one thing, white sapphires are more abundant than diamonds, which makes them more affordable.

And while both stones have excellent clarity, white sapphires typically have fewer inclusions than diamonds. As a result, white sapphires offer a great alternative to diamonds for those looking for a beautiful and durable white gemstone.


When it comes to engagement rings, many couples are torn between diamonds and white sapphires. Both stones are beautiful and durable, but they each have their own unique advantages.

When it comes to brilliance, diamonds tend to have a higher refractive index, which means they sparkle more than white sapphires.

If you’re looking for a gemstone with both brilliance and sparkle, white sapphire is a great choice. Sapphires are typically known for their blue color, but they actually come in a wide range of colors, including white.

White sapphires have a similar chemical composition to other sapphires, but they lack trace impurities that give other sapphires their color. As a result, white sapphires are typically much more affordable than other colored sapphires. And because they’re colorless, white sapphires can be used in a variety of jewelry styles.

If you’re looking for a beautiful and versatile gemstone, white sapphire is a great option.


If you’re considering a white sapphire or diamond for your next piece of jewelry, it’s important to compare prices before making your purchase.

While diamonds are typically more expensive than white sapphires, the price difference can vary depending on the quality of the stone. In general, diamonds are graded on a scale from D (the highest quality) to Z (the lowest quality). The higher the grade, the more expensive the diamond will be.

However, it’s important to note that even a lower-quality diamond will be more expensive than a high-quality white sapphire. Also if you ever intend to sell your jewelry a diamond will always provide a greater return on investment than other gemstones.

What is a White Sapphire?

A white sapphire is a precious gemstone that is often used in jewelry. It is typically colorless or pale in color, with a Mohs hardness of 9.

White sapphires are found in a variety of locations around the world, including Sri Lanka, Madagascar, and Australia. The stone gets its name from its color, which is caused by the presence of trace minerals in the stone.

In addition to being used in jewelry, white sapphires are also popular for use in engagement rings and other fine jewelry. Thanks to their durability and beauty, white sapphires are a popular choice for those who are looking for a precious gemstone that will last a lifetime.

Are White Sapphire Gemstones Valuable?

While sapphires come in many colors, the most valuable and rare sapphires are typically blue. However, white sapphires are also quite valuable, and are prized for their clarity and brilliance.

In general, white sapphires tend to be less expensive than blue sapphires, but still command a high price tag. Because of their popularity, white sapphires are used in a variety of jewelry, including engagement rings, pendants, and earrings.

While they may not be as valuable as blue sapphires, white sapphires are still beautiful gemstones that are well worth the investment.

Why Choose a Diamond Alternative for Your Engagement Ring

It’s no secret that diamonds are expensive. In fact, the cost of a diamond engagement ring can be quite prohibitive for many couples. If you’re looking for a more affordable option, there are plenty of beautiful diamond alternatives to choose from.

For instance, moissanite is a unique gemstone that looks very similar to a diamond. It’s also extremely durable and resistant to scratches, making it a great choice for an engagement ring.

Another option is cubic zirconia, which is more affordable than moissanite but still offers a brilliant sparkle.

Whether you choose moissanite, cubic zirconia, or another diamond alternative, you’ll be able to find a beautiful and affordable engagement ring that will suit your unique style.

Bottom Line

While diamonds may be the first stone that comes to mind when you think of engagement rings, there are many other options to consider.

One gemstone that is often overlooked is the white sapphire. White sapphires are just as durable as diamonds, with a hardness of 9 on the Mohs scale. They are also very affordable, making them a great option for couples on a budget.

In addition, white sapphires have a beautiful luminous quality that is sure to impress your future fiance.

So if you are looking for an engagement ring that is both beautiful and budget-friendly, consider choosing a white sapphire.
