How to Recognize a Genuine Natural Stone? The Kumari Legacy Authentication Guide

Given the success of minerals and lithotherapy, the market includes many imitations (plastic, colored glass, or modified low-grade minerals). To help you make the right choice and ensure the authenticity of your pieces at Kumari Legacy, here are the main signs to look for and the pitfalls to avoid.

1. Signs of Authenticity: How to Test a Stone?

Before concluding that a mineral is authentic, several reliable physical characteristics can put you on the right track:

• Weight: A genuine natural stone is generally heavier than a plastic or resin imitation. The mineral has a high density that gives it a pleasantly surprising sense of "heaviness" in the hand.

• Temperature: To the touch, a real stone is always cool. Unlike plastic or low-grade glass, which quickly reach room temperature, a natural mineral takes time to warm up when held in the hand.

• Natural inclusions: Absolute perfection is often suspicious. An authentic natural stone almost always shows tiny imperfections inside: micro-cracks, veils, small irregularities or inclusions of other minerals.

• Color variations: In nature, hues are never 100% uniform. An authentic stone displays subtle nuances, gradients, or lighter and darker zones, unlike synthetic imitations which are often too regular.

2. The Most Common Fake Stones and Imitations

Certain deceptions are very widespread in the global mineral market. Here are the most frequent cases:

• Blue-dyed howlite → sold as turquoise: Howlite is a porous white stone that absorbs pigments very easily. Dyed blue, it convincingly imitates turquoise. To spot it, examine its surface: real turquoise shows natural dark veins (matrix), while dyed howlite sometimes shows areas where the color has "bled through" too uniformly or fades slightly with acetone.

• Synthetic (or hydrothermal) quartz: Very common on the market (particularly for very vividly colored amethyst or citrine), synthetic quartz is lab-made. It's often flawlessly pure, completely free of inclusions, with over-saturated colors (like a fluorescent yellow-orange citrine obtained by heating amethyst).

• Colored glass: Used to imitate black obsidian, rose quartz or moonstone. The foolproof test lies in examining it under a magnifying glass: if you spot small round air bubbles, it's definitely glass and not a natural stone.
