There are many different colored quartzes, and the name tells you what color the quartz is. If you hold two crystals of similar size in your hands or put them on a digital scale, a fake crystal will weigh less or feel lighter than a real crystal because the fake is probably made of glass. In plain English, real rose quartz has a solid heavy feel to it and weighs more than glass, especially when comparing large crystals. If the specific gravity reading is 2.5, it’s a fake glass crystal.Ĭlosely related to specific gravity above, real rose quartz is heavier than glass (which is why its specific gravity or relative density is higher than glass). If the specific gravity is 2.65, then you have a real rose quartz in your hands.This gives you the crystal’s specific gravity or relative density. Divide the true weight of the crystal and water weight by the true weight of the water-only weight.

So these are the weights without the container. You now have the true weights of the water and the water and crystal.

Subtract the weight of the empty container (first measurement) from the weight of the water-filled container (second measurement) and the water and crystal weight (third measurement).

Add the crystal to the water, and write down the weight to two decimal places.

Add water to the container and weigh it again, again writing down the number to two decimal places.

Make sure the container is large enough to hold some water and the crystal you are testing.

Weigh the container you’ll be using for this measurement, writing down the weight to two decimal places.

Here are the steps to calculate the specific gravity of a rose quartz crystal:

The specific gravity or relative density of rose quartz is 2.651, which can be measured using a digital scale that shows at least two decimals. To calculate this, we measure how much “space” the crystal takes when we drop it in water. Real rose quartz… Has a specific gravity of 2.65Ī fairly accurate and reliable way to tell if rose quartz is real is to measure its specific gravity. Most fake quartzes are made from glass, so below you’ll find 16 ways to tell the difference between real rose quartz and factory-made glass quartz.īy the end of this post, you’ll know 16 things you can do to test if a crystal is real rose quartz or an imitation. You’re probably here because you’re wondering if a crystal you have is real rose quartz or a fake.
