How are diamonds made naturally?
Diamonds are formed naturally in the earth’s mantle under conditions of extreme temperature and pressure. This is the critical temperature and pressure needed for natural diamond formation and stability. The carbon atoms then bond together under the extreme environment, creating a diamond.
Do VVS simulated diamonds pass diamond tester?
Yes! Lab grown diamonds test positive on a diamond tester because they’re made of crystallized carbon, just as mined diamonds are. Although, because some HPHT diamonds may carry impurities (although unnoticeable to the naked eye), there is a chance they could test as moissanite or non-diamond.
Does simulated diamond last?
The quality of the stone will retain over time, just as those of every unique natural diamond do. Other diamond simulants will vary in quality based on the composition of the stone in the lab process.
Are simulated diamonds fake?
Simulated diamonds are also known as diamond simulants and include things like cubic zirconia (CZ), moissanite, and YAG. They are real diamonds but not grown by Mother Nature.
Are cheap diamond testers accurate?
How Reliable Are Diamond Testers? Diamond testers are one of the most accurate tools to check a diamond for authenticity. However, you should know that testers that rely on thermal conductivity can mistake a moissanite for a diamond because these two stones are very similar in the way they conduct heat.

Will a diamond tester work on black diamonds?
We noticed that many times local jewelers will perform the test using regular diamond testers which measure the light reflections from the inside of diamonds. Because black diamonds are opaque, this test will most likely give an inaccurate result and the device will show that what you have is a moissanite.
Will sandpaper scratch a real diamond?
No, sandpaper cannot scratch a diamond. The hardness of sand paper grit ranges between 7 and 9 on the Mohs scale, which makes sand paper softer than a diamond. Many people use sandpaper to test if a diamond is real or fake.
Will a jeweler steal my diamond?
Yes, you can trust your jeweler. Yes, you can leave your rings for repair. And, if you want to know the honest to God’s truth, most jewelers wouldn’t attempt to steal your diamonds anyway. This is because most diamonds are either small in carat weight, or flawed (And jewelers already have tons of those diamonds).
