Are you looking for the best diamond replacement gemstone for your engagement or special occasion ring that still gives the look and feel of real diamonds for years to come?
Traditionally, diamonds were a go-to choice for couples looking for an engagement ring. Diamond engagement rings have a premium, luxurious feel to them, owing to the brilliance, sparkle, and rarity of the diamond gems adorning the ring.
However, of late, an increasing number of couples started searching for the best diamond replacement gemstones for their special lifetime ring.
The millennial couples have clear-cut priorities when it comes to selecting their forever engagement ring— they want to ensure their centre gem is conflict-free, ethically sourced, durable, beautiful and importantly, fits their budget. Couples are tending to be particularly conscious of allocating more budget to their future life together than spending it all in an enormously expensive diamond ring. As a matter of fact, many couples are breaking the norms and opting for premium diamond replacement gemstones for their engagement ring, such as Moissanite.
Selecting from the myriad of luxurious diamond replacement gemstone options can be tricky unless you know what value they bring to the table – or rather to the engagement ring.
There are several options to choose from; however, in this guide, we will primarily focus on three of the most popular diamond replacement gemstones such as Moissanite, white sapphire, and white topaz.
Let’s dive in…
Increasingly, most would agree that the best diamond replacement gemstone is Moissanite making it one of the most sought-after gemstones among millennial couples for their engagement ring option.
Moissanite has an interesting history that dates back to 1893. It is a unique gemstone that is in fact rarer than diamonds in its natural form. As such all Moissanite is lab-created in advanced high-tech laboratories, making it identical to earth formed Moissanite, in terms of chemical properties and composition.
What makes Moissanite a leading gemstone in the engagement ring market is its brilliance, sparkle, durability, and, of course, affordability.
In fact, with a higher refractive index (2.65-2.69) than diamond, which refers to its brilliance, Moissanite has more sparkle than even a diamond. Likewise, with a 9.25-9.50 score on the Mohs Scale of Hardness, this popular diamond replacement gemstone is also very close in terms of durability to a diamond, which makes it ideal for everyday wear for the long term. In terms of affordability, Moissanite engagement rings cost much less than a comparable diamond ring.
If you are considering a Moissanite gemstone ring, you may like to know that Moissanite gems tend to have slight “rainbow” like flashes in their sparkle, more so in larger gem sizes. Comparatively, diamonds have more of a white sparkle.
Regardless of the differences, Moissanite has emerged as the top choice for many couples in Australia as the best diamond replacement that looks identical.

2. White Sapphire
White sapphire is another popular alternative to diamonds, which is used in engagement rings for its hardness, sparkle, durability, and similar look to diamonds.
So why is white sapphire considered a viable gemstone alternative to Diamonds, you ask? Here are some popular reasons.
Hardness: In terms of hardness, white Sapphires score a 9 on Mohs Scale of Hardness, meaning they have a lower rating than that of Moissanite (9.25-9.5) as well as Diamond (10). However, they are still considered durable and ideal for everyday wear. You would want to however be a little more careful with the white Sapphire engagement ring as it tends to wear (especially the edges) more easily over the years.
Both high-quality grade, white Sapphire and Moissanite gemstones appear colorless. However, moissanite always appears clearer with more sparkle, than white Sapphire as it tends to attract more dirt and scratch more frequently. This essentially means Sapphire gemstones require more cleaning to retain their appearance.
Moreover, in terms of sparkle, Moissanite has an advantage over white Sapphire gemstones. Not only does Moissanite have a higher Refraction Index (2.65-2.69) than Sapphire (1.77) and therefore much more sparkle (for the longterm), it also has more fire (0.104) compared to white Sapphire (0.018), which refers to its coloured light flashes.
3. White Topz
White Topaz is also a versatile gemstone that is quickly emerging as one of the popular diamond replacement gemstones among millennial couples in Australia.
The name of this gemstone is derived from Topazios – the old Greek appellation for an island in the Red Sea.
According to the Gemology Institute of America, the colour of the white Topaz gemstone is essentially caused by defects or impurities in its crystal structure rather than its chemical properties.
Brilliance/Sparke & Hardness: When it comes to sparkle and durability white topaz has some shine and a high hardness score however it certainly falls short compared to Moissanite. White Topaz has a brilliance refractive index (RI) of 1.6 and scores an 8 on the Mohs scale of hardness so extra care would be needed if selected for everyday wear. It should also be noted that as a result like white sapphire, white topaz can sometimes appear dull and cloud over time compared to when you originally purchase it.
Moissanite is by far considered the best diamond replacement gemstone around for a special ring, that gives the identical look and feel of diamonds. From colour to sparkle to brilliance to hardness, Moissanite comes out the winner in every department, which explains its rising popularity with Australians and the modern couple.
