Frequently Asked Questions

What is the difference between a Natural diamond, a Lab grown diamond, a Moissanite, and a Cubic Zirconia?

Both Natural Diamonds and Lab Grown Diamonds are real diamonds. The difference being, lab grown are grown in a lab while natural diamonds are formed in the earth. They are chemically and optically identical to each other.

Lab Grown Diamonds are created in a controlled environment. This environment reproduces the earth’s conditions when growing a natural diamond. This results in the chemical and physical properties of a Lab Grown Diamond being identical to the ones grown naturally. Unless a lab grown diamond has an engraving stating that it is lab grown, even a trained eye will not be able to tell the difference between a lab grown diamond and a natural diamond.

Lab Grown Diamonds are very different in price. They are usually about 30% less than a natural diamond of the same size and quality.

There is a big difference between diamonds (both Natural and Lab Grown) and a CZ (cubic zirconia) or a Moissanite.

A CZ does not have the same chemical makeup as a diamond, under a trained eye the difference is obvious. This is a man- made, very inexpensive alternative to a diamond. It is often meant to mimic a diamonds look and feel as closely as possible.

A Moissanite is a stone of its own. The chemical makeup is not the same as a diamond or a CZ. It has its own chemical makeup and was first discovered in a crater in Arizona in 1893. Most Moissanite’s are now Lab Grown.

How do I know I will be getting my diamond back after you have worked on it and that it hasn’t been switched out?

It’s unfortunate that this is a question so commonly asked. To be completely honest there really is not a 100% foolproof way for you to know if it is the original stone. That is, unless you are one of the few that has a serial number or other custom engraving on the side of the diamond. In that case you can have the jeweler read it back to you, or look at it yourself.

At The Gem Smith we want you to feel comfortable leaving your jewelry with us. When taking your item in for a repair or cleaning we use a diamond tester to test that the diamond is real, it is then checked off on our repair sheet. Measurements should also be taken, especially on larger stones.

We will also write down any inclusions, chips, breaks, or any other issues or markings. When you pick up your item you can always ask to have it tested again, so you know it is a diamond.

We do however recommend to those that are still uneasy that they not leave it with us. In our opinion it’s just not worth the headache for either side. We recommend you always take your jewelry to someone you trust.

Can I watch you do the repair?

The simple answer to this is no.

There are many steps to a repair and they are not all done right after one another. For example, jewelry often times stays in our cleaner for 24 hours before any work is done on it. Many times items need to be cleaned in between steps.

Another reason is it is simply too much pressure. Just like most jobs you do your best work when there is not someone standing over your shoulder.

What happens if something goes wrong during my repair?

If something goes wrong we will call you and let you know what is going on. For example if a stone happens to break, we will have you come in and decide what you want to do. If it is something that needs to be replaced, we will find a stone of similar quality and replace it at no extra charge (you’ll still pay the price of the original repair.)

Please note that while this does happen on occasion, it is not at all common.

At times imperfections in a stone can add to the chance of chipping or breaking. If this is the case, the customer is responsible for those losses. If we see something that concerns us we will warn you before we do any work and it will be up to you whether or not to continue with the repair.

Are synthetic stones fake or real stones?

Synthetic simply means the stone was produced in a lab. When used correctly, synthetic means the stone is chemically, physically, and optically the same as the natural stone of the same type.

Many people confuse synthetic with imitation or simulant stones. Imitation or simulant stones do not have the same chemical makeup as the stone it is imitating.

So what is a simulated stone?

A simulated stone is a stone that is acting as the stone it is imitating. It does not have the same physical or chemical properties.


Simulated = Similar

Synthetic= Authentic
