Diamond vs. Moissanite Engagement Ring: Which Is Better?

Diamond vs. Moissanite Engagement Ring: Which Is Better?

Diamonds are typically the stone of choice when it comes to engagement rings. Contrary to popular belief, the main dazzler on your sparkler doesn’t always have to be a hefty diamond. There are many stones to choose from, and one of the most popular alternatives is moissanite. 

In terms of appearance and durability, only a trained eye can differentiate a diamond from a moissanite. However, does it really compare with a diamond? Let’s find out.

Getting to Know Diamonds and Moissanite


Diamonds are solidified carbon formed under extreme heat and pressure, making them one of the hardest and most intricate minerals on the planet. They are scattered all around the world so they are not rare per se, but a quality diamond is definitely hard to find. Because of their history and quality, diamonds are quite worth a price tag.


Compared to diamonds, natural moissanite is considered very rare and extremely expensive. Natural moissanites are products of meteorites, and their quantities on Earth are not enough for jewelry making. Because of this, the moissanite we know today is designed in a lab setting. 



Saying that diamonds are durable is an understatement. They are one of the hardest natural substances on Earth, scoring 10 on the Mohs scale of hardness.


However, moissanite is quite a contender. At 9.25 on the Mohs scale, moissanite is even harder than sapphire, ruby, and emerald, which are all popular engagement ring gemstones. Another surprising fact is that moissanite is more resistant to heat than diamonds. 



Diamonds are expensive, hands down. A small 0.30-carat diamond already costs P30,000. For comparison, Marian Rivera’s 2.48-carat engagement ring costs P2.8 million. When the three-month salary rule is factored in, the total cost of the ring may not suit everyone’s budget. 


Moissanite, a sophisticated dupe for diamond, is the less-pricier option. 1 carat will set you back about P30,000.




Diamonds are highly regarded for their brilliance and sparkle. They have a refractive index of 2.42, a high measure of scintillation and brilliance, which means the shine of a diamond is nothing less than opulent.


Surprisingly, moissanite has a higher refractive index than diamonds at 2.65. While moissanites literally shine brighter than diamonds, they tend to give off a “rainbow effect.” This is appealing to some people, but others may not like the noticeable flashes under natural light. However, the rainbow effect is not that evident in smaller moissanite stones.

Which Is Better?

There is no definite answer, as it all depends on your preference and budget. 

If you’re aiming for a big-stoned engagement ring, but don’t want to spend your entire savings on it, we recommend going for moissanite. Meanwhile, if you’re on a budget but your heart is set on diamonds, small stones are your best bet! 

Diamonds may be the standard when it comes to engagement rings, but moissanite comes in at a close second.
