Frequently Asked Questions
Which moissanite shape looks the most like diamond?
Because diamonds have so many different cuts and can vary so much in quality, you can almost say all shapes of moissanite look like some variation of diamond; it depends on which particular diamond cut you are comparing to. However, there are some diamond cuts that are very common, and therefore familiar to most people, such as round, oval, cushion, emerald, princess, asscher, and pear. When comparing moissanite to these common diamond cuts, you would be hard-pressed to tell the difference. In general, a round moissanite has the most diamond-like properties because the ideal cut diamond has very standard proportions, which can be replicated in moissanite. There is no standard for fancy cut diamonds, and no ideal cut grade. Just the cushion cut alone has over 10 completely different cuts.
I’ve only heard of Charles and Colvard moissanite. Why should I buy a different brand?
Charles and Colvard have been around since 1995, and were the first to facet silicone carbide into gemstones. They had a patent on moissanite until 2015, so no one sold anything but Charles and Colvard for 20 years, and that’s the reason why their name is the most recognized. However, since their patent expired, many other companies started to produce moissanite and come up with their own brands, and now things are a little confusing for the consumer. The truth is, like diamond, moissanite is a material–a commodity, if you will. The brand of a stone is not as important as the cut and quality of the stone. If you are looking for crushed ice oval cut, Charles and Colvard doesn’t cut it. If you are looking for an elongated cushion, Charles and Colvard doesn’t cut that either. That’s where other brands like Harro Gem come in. We specialize in cutting the stones that Charles and Colvard doesn’t cut. We also have our own proprietary cuts that are different than what you will find on the marketplace.
Our goal is to make moissanite look as much like diamond as possible, and we have gone back to the drawing board many times to perfect our cuts. If you cut a moissanite exactly like a diamond, it will look different. Therefore, every facet needs to be adjusted to match the brilliance and fire that a diamond produces. When shopping for moissanite, chose a trusted brand that can deliver the exact product you are looking for.
How long will moissanite last, and how should I care for it?
Moissanite should last for generations, or as long as diamond. Unlike cubic zirconia, moissanite doesn’t go cloudy over time. It also isn’t as prone to chipping or scratching as cubic. As long as moissanite is well cared for, it should last indefinitely. Just like diamond, moissanite should be cleaned regularly. You can use regular jewelry cleaner to wash off oils, dust, soap scum, fingerprints, etc. For more stubborn stains, you may need to use silver polish and a cloth to restore its original lustre.
When resizing your ring, the moissanite stone doesn’t need to be removed because it can handle the high heat from soldering. However, the jeweler needs to make sure he or she cleans the stone very well before applying heat, otherwise any oils on the stone will get baked on. Over time, this baked on oil will attract dirt, which will become extremely hard to remove. A jeweler should put the ring in a mild acid bath and dry it completely before applying heat.
What is a brilliant cut and what is a crushed ice cut? And what is a diamond cut?
A crushed ice cut generally applies to elongated shapes, such as ovals, cushions, pears, and radiants. With moissanite, the standard cut that most companies cut is the brilliant cut. It usually sparkles a bit more and has well-defined facets. The crushed ice, on the other hand, has broken up facets, much like broken ice. For the most part, elongated diamonds will have a crushed ice appearance, even when they are cut like a brilliant. One reason this happens is because diamonds are cut shallower than moissanite to save material, since diamonds are very expensive. A shallow, elongated stone will always give a stone a crushed ice look because of how the light refracts. Since moissanite is much less expensive than diamond, it can be cut deeper to give the stone well-defined facets like the top stone in the video. The higher refractive index of moissanite helps with this as well.
The diamond cut (the middle stone in the video) is somewhere in between the brilliant and crushed ice in appearance. It looks very similar to a brilliant cut oval diamond, which under certain light, looks like crushed ice, but the facets are more in-focus when compared to the bottom stone.
The video below shows the difference between the three cuts: brilliant cut (top), diamond cut (middle), and crushed ice cut (bottom).
What are windmills on an emerald cut?
Windmills are extra facets added to the bottom of the emerald, which makes it look like there are four windmill blades going from the corners to the center of the stone (see the stone on the left below). Having windmills or not is completely personal preference because diamonds are sometimes cut one way or the other. The difference is usually quite subtle, but if you want the corners to be slightly more defined, choose the windmills.
What size should I get? Does moissanite look more “fake” as it gets larger?
What I always tell people is, get the size you want. However, while many people might want a large stone, they don’t want their moissanite to look “fake” (I put fake in quotes because moissanite is a REAL stone, and there’s nothing fake about it). Moissanite’s price usually increases linearly as the carat size increases, ie. a five carat moissanite will cost approximately five times more than a one carat. Diamond prices, on the other hand, go up exponentially as the carat size increases. A good quality five carat diamond can cost 20 times more than a one carat diamond of similar quality. Because moissanite is lab-created, it’s comparable to a high quality diamond in its cut, clarity, and color. That means the five carat moissanite that you’re wearing could look like a $150,000 diamond. Unless you’re rich and/or famous, you might have a hard time convincing people your rock is a diamond. If you simply love moissanite for the beautiful stone that it is, this shouldn’t matter to you.
