We will help you to figure out the reasons in this esay.

Firstly you must know,

What is The main factors determining the sparkle of your product？

When you see the stones shining, it comes from the excellent effect of reflection. The lights put on the moissanite will be completely reflected from the side they come, some of which slip away in other directions, scattered into colorful lights. For a perfect moissanite, the lights from other directions (not the front) will be reflcted back along the way they come. That leads to the result that how shiny the stone is depends on the intensity of light from the direction you look at it.

For pendants with hollow back, the holes they leave on purpose around the base of stones, which are supposed to make more lights from all directions go through the stones, are actually useless. The physical reason is listed above, let alone the fact that when the pendant sits on your chest, how can the lights come through the back of it? 

For solid-back pendants, the silver background we set is like a mirror, making sure all lights, including those may slip away, reflected perfectly. Even in gloomy environment, the strengthened gathering of lights along with the metallic luster will make the stones marvellous. These are some examples.

Secondly,

For custom jewelry with thousands of stones, what issues having a hollow back can lead to ？

It is a common sense that the moissanites are similar with real diamonds. They are easily covered by dust and oil. With holes around them, the wider they are exposed to the environment, the sooner they get “grey”. Maybe in several weeks your pendant will be like this, SOS!

All these holes on the back of the pendant just speed up the oxidizing period of your pendant, with no any other benefit.

With solid back, the metal part behind the stones will be like a shield to protect them from getting covered by dust, water or oil while you wear the pendant, which will make the shinny look to last for a longer time and reduce the time you need to clean it.  

Lastly,

the quality of the stones themselves is, of course, crucial.

Same as real diamond, the principles of 4C also work for moissanite, among which the clarity and cut will influence the shine effect the most.

• Clarity: What’s hiding inside a diamond and why does it matter?
• Cut: How do the shape and crafting of a diamond play into its allure

We use vvs moissanites in D color, which is the top quality. And the stones we normally use are in brilliant cut, which will bring excellent effect. A moissanite in perfect cut will generate the best shine effect.

As you can see, all the lights going through it will be gathered and sent to your eyes, no matter how faint the light is.

It will always be like a mirror to make sure you can see the shinny look of it.
