Light crystal quality is an important consideration for many buyers, but it’s not always easy to figure out what makes one piece better than another. There are plenty of factors at play when it comes to how well a stone sparkles or refracts light, from its color and weight to the purity of its cut. This post will explain these different aspects that can help you judge the quality of your crystal purchase!

How to Judge Lighting Crystal Quality


If you are thinking about buying a certain type of quartz crystal and want to know if it’s good quality, the first thing you need to do is take a look at its color.

If your crystal is clear and transparent, then it’s probably high quality. This means that there should be no visible cloudiness in the stone, nor should there be any tint or tinge of color. If your crystal has a milky or opaque appearance when viewed from all angles (or even just one), then it’s most likely not going to be very useful for sparkling purposes. The same goes for crystals that have any kind of yellow or brown tint—they’re not very good either!

When you feel the weight of a crystal, it will give you some information about its quality. A heavy crystal is of higher quality. The reason for this is that cheaper crystals are made from plastic or resin and so they will be lighter than a real crystal. If your crystals are very light, then there is a chance that they could break easily.

In addition to this, if you have purchased fake crystals then they might not have as much substance as real ones and therefore won’t feel as heavy in your hands.


Sparkling is the result of light reflecting off of the crystal’s surface, and the more sparkle there is, the better. You can see this best in a dark room, where the crystals will shine brightly on your walls and windows. The best way to judge sparkling quality is by looking at individual pieces of crystal and comparing them against each other.

Hardness refers to a material’s ability to resist scratching. In other words, how easily does it scratch? The hardness of the crystal is measured by scratching the crystal with a diamond. Quality crystals should be very hard so that they are less likely to scratch and break.

Crystal quality depends on its appearance

The more facets a crystal has, the better it will reflect light and look like a diamond. When choosing a crystal, it is important to look at the way it refracts light. A well-cut crystal will have many facets that reflect light in different directions, causing it to sparkle more than other crystals with fewer facets. When looking at a crystal, hold it up to the light and see how much of its surface area reflects back into your eyes. If most of the crystal’s surface area reflects back into your eyes, then it is likely a very high quality crystal.
