Diamond vs. Moissanite vs. White Sapphire November 07 2013
One of the diamond alternatives that I offer is a Moissanite. A Moissanite is a lab-grown gemstone (so it's eco-friendly and conflict-free) that is slightly harder than a sapphire and next in hardness to a diamond. It has as much sparkle as many diamonds, but also has more fire than most diamonds. Fire is the rainbow flashes that you see off a stone. To the average person viewing these two stones with their naked eyes, they would not be able to distinguish the difference between a Moissanite and a diamond. So it is a great option for someone looking for an inexpensive diamond alternative.
There are two types of Moissanites, classic and Forever Brilliant. A Forever Brilliant Moissanite when viewed on a white surface is whiter & brighter than the classic Moissanite. The classic Moissanite, if it were graded on a diamond color scale, would be I-J range and the Forever Brilliant Moissanite would be in the G-H range.
Since still photos don't really show the flashes that you get with faceted stones, I made a video so that you can see the difference.
Another diamond alternative that I frequently work with is white sapphire. There is quite a big difference in the fire and brilliance between the two. The white sapphire is great for someone who wants an affordable diamond alternative that is also subtle and not too flashy. Moissanite on the other hand is much more blingy, and is more similar in appearance to a diamond than a sapphire. Below are a couple of pictures that compare them.
A white topaz has a Mohs hardness of 8, white sapphire has a Mohs hardness of 9, a Moissanite has a Mohs hardness of 9.25, and a diamond is a 10. The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. But that scale only tells you how they rank, and diamonds rank as the hardest. What it doesn’t tell you is that a diamond is actually 4x harder than a sapphire. A sapphire being 400 on the hardness scale and a diamond being 1600.
