How to Tell If a Gemstone Is Real or Fake: Quick Buyer’s Guide

Gemstones hold beauty, meaning, and often great value. But in a market filled with synthetic and imitation stones, knowing how to tell if a gemstone is real or fake is essential—especially if you are buying for astrological, spiritual, or investment purposes.

Here is a quick and simple guide to help you make smarter decisions before you buy:

Ask for Certification Always request a certificate from a trusted gemological lab like GIA, IGI, or IIGJ. A certified gemstone comes with proof of authenticity, including details about its origin and quality.

Check Clarity and Color Natural gemstones usually have small inclusions or internal flaws. If a stone looks too perfect, too clear, or unnaturally vibrant, it may be synthetic or glass.

Feel the Weight Real gemstones feel heavier compared to fake ones made of plastic or glass. If the gem feels unusually light, it is worth questioning.

Touch the Temperature Authentic gemstones stay cool, even after being held for a few seconds. Imitation stones often warm up quickly in your hand.

Look at the Cut Genuine stones are usually hand-cut and may have slight imperfections. Fakes tend to be machine-cut and look overly symmetrical and polished.

The best way to avoid being tricked is to buy from a trusted source. At Shiv Parvati Gems, every gemstone is certified and ethically sourced—so you can shop with full confidence.

What is a Black Onyx Gemstone & Where Does it Come From

Black onyx gemstone is a variety of mineral chalcedony. The presence of iron oxide gives it its characteristic black hue. Want to know its history and origin? It has been used in jewelry and carved into other objects since the ancient Egyptians.
