The SAM by Presidium and Synthetic Diamond Screener II are two powerful tools that can help you identify and separate natural diamonds, laboratory-grown diamonds, moissanites, and diamond simulants quickly and easily. Whether you are a jeweler, gemologist, or hobbyist, these tools are essential for reliable diamond testing. 

Here's how you can use them in just two simple steps:

Step 1: Use the SAM by Presidium

The SAM by Presidium is a device that helps you differentiate between diamonds, moissanites, and diamond simulants. The device will emit a series of beeps and lights that will indicate whether the stone is a diamond, moissanite, or diamond simulant. The device is calibrated to provide reliable readings, and it takes only a few seconds to complete the test.

Step 2: Use the Synthetic Diamond Screener II

The Synthetic Diamond Screener II is a device designed to identify whether a diamond is natural or laboratory-grown. The device will emit a green light if the diamond is natural or a red light if it is laboratory-grown. This step takes only a few seconds, and it will tell you whether you are dealing with a natural diamond or a laboratory-grown diamond.
