Brilliant Cut vs Step Cut : The Age Old Battle of Gemstone Cut Styles

- In this video I break down the differences between the step cut and the brilliant cut including some real world emerald examples. Step cuts have historically been the cut of choice for gem cutters since ancient times and only recently in the 20th century has the brilliant cut been the object of so many cutters affections. Let's see how they compare which it comes to yield, color, sparkle, and more.
Please note that in this video, I go back and forth between the terms mixed cut and step cut, but in fact all my examples are pure step cuts and there are actually no mixed cuts in this video. My mistake. :)

Hey Justin,
I came into this with next to no knowledge, but it was so well explained, I was able to understand. Thanks mate
I cut my first stone by hand 3 days ago on a cutting board with diamond sand paper. It was a basic emerald one step cut with a rectangle table and rectangle base. What a fun experience. Now I'm hooked. In order to increase it's scintillation and brilliance I recut the pavilion to a more "brilliant style" 4 triangles. Your other video now informs me this was a basic Table Cut. In doing so, the red garnet lost a lot of color saturation and a lot of weight, but the stone does have better light refraction. I am conflicted over the result. It lost so much color I think I should have left it alone. This is the perfect video I needed to see. Many more "mixed cut" in the future. As with yourself, the history of the art is important to me. I like to see how nice a stone can be had with the simplest of equipment.
Hey Justin,thanks for your precious advice and for the name of the book that you showed in the video.
Wow, what a great video. I've got to check out that class! I've wondered for years why you don't see many emeralds in a brilliant round cut, this totally makes sense.
Excellent Justin🙌😇 thanks 💞🎶
That was really interesting Justin. Thanks.
Awesome lesson ! Thanks Justin
Great video! Cheers!
EXCELLENT INFO! Thank you!!!
Aesthetically, I rarely enjoy step cuts, but now that I see the gem's yield 😮
Very interesting comparison, you do good work!
Very nice. Thank you posting
Very interesting
Great video Justin. When you are sitting at the quill thinking "I am going to grind away more of my $4k/ct rough to do that," it gets real quickly.
I Will try on Aquamarine. There some patern with the better angles to aply?
Justin, while I have an awful lot of respect for you as both a man and a cutter, I have to tell you that in this particular video, your “lesson” doesn’t pass the smell test - and I say this as someone who’s stood on both sides of the proverbial fence, as both an American faceter using masted machines and a former professional lapidary to the trade, who had cutting shops in the NY area from 1976-98. If you’re going to compare step to brilliant cuts, do so with a material
how hard was it to move to Bangkok ? You must be all over rough stones there! I just can't fathom the cost of good rough. I have to deal with gem show junk. Enjoyed your take on this and have always cut brilliant.
I am curious, you have mentioned as the light takes more time to travel, it produces more color, does that also increase “darkness”?
What does the bulk pavilion do to gemstone? Bigger window?
