However, this test is not considered very good as coated fake moonga gemstones can also show the same effects.

One can also perform this test with Nitric Acid (Lemon Juice) and look for bubbles or effervescence.

3. Scratch Test

Try to scratch this stone with your nail and carefully hear the sound it produces. If it sounds like the scratching sound of glass or plastic, it’s probably a fake one and made up of plastic or glass.

4. Turmeric Test

Take a piece of raw turmeric and rub it against the stone; if it leaves a red mark on the turmeric, it is a fake or an imitation of moonga stone, not a real one. Turmeric color will not change if it’s a natural moonga.
