Hi everybody, Dan Moran here from Concierge Diamonds. This is my first video from my new office. I'm pretty excited. We recently moved to a larger and more comfortable office with a ridiculous view. If you're here in LA, please come and check it out. So first things first housekeeping. Our new address is 550 South Hill Street, Suite 1555, Los Angeles, California, 90013. If you're looking for me, that's where you'll find me. Today's topic is polish. You may be aware that different gem labs all grade different aspects of a diamond's cut and one of those is the diamonds polish. What does that grade refer to? What aspect of the diamonds cut? Does the polish grade really assess? Well, the polish grade assesses the exterior finish of the stone. In other words, if I'm looking at the stone, it doesn't reflect the various angles or ratios of different facts. It doesn't have anything to do with the ratio of depth to diameter. It doesn't have anything to do with the length with or depth of the diamond. The polish strictly and solely refers to the outer surfaces of the stone and the way they're finished. It really is as it sounds. It's the polish. Each facet, when a diamond is being cut, is polished down on a diamond wheel individually. And the uniformity and evenness of that polish is what the polish grade really reflects. It's about getting that surface as perfect as you can, as perfectly even and perfectly flat as you can to maximize the brilliance of the surface because of course if the surface is uneven, wavy or rough, that will tend to disrupt light flow through the diamond. So the polish grade of a diamond reflects the surface finish of a stone, which by the way means it's also the easiest of diamond grades to correct. If you cut a diamond and you're not happy with the polish grade, you can repolish facets without really dramatically changing the weight of the diamonds and improve your polish grade. And a lot of cutters will do that. So that's what polish is about. It's just the finishing on the exterior surfaces of the stone. I hope you found that helpful. If you have any questions, please email me, call me, find me on Reddit or comment down there. Thanks.
