Heated vs. Unheated Gemstones: What Every Buyer Should Know

When it comes to gemstones, one question always creates confusion: Should gemstones be heated or always remain unheated?

Many customers are told by astrologers or jewellers that only unheated gemstones are “real”. This is a half-truth. Let’s clear the misconceptions and explain what heating and treatments really mean.

Why Are Gemstones Heated?

  • To enhance natural beauty – Heat can improve a gemstone’s color and clarity, bringing out the sparkle hidden inside nature.

  • To make gemstones affordable – Without heating, only a tiny percentage of gems show top quality. Heating allows more people to enjoy beautiful gemstones at a fair price.

  • Permanent results – Heating is an age-old and globally accepted practice in the gemstone trade. It is stable and does not reduce the gem’s life or astrological effects.

Example: Rubies and sapphires are very often gently heated to achieve their vibrant color.

The Difference Between Heated and Unheated

  • Unheated gemstones: Rare, naturally beautiful, extremely limited in supply, and therefore much higher in price.

  • Heated gemstones: Natural stones that have undergone careful heating to enhance their look. They remain 100% natural and are widely used across the world.

  • Other treatments: Some low-quality gems are glass-filled, dyed, or coated. These are less valuable and must always be disclosed.

Does Heating Reduce Astrological Benefits?

This is one of the biggest myths in the market.
Astrologers sometimes misguide customers, saying only unheated gemstones “work.” In truth:

  • Heating does not destroy the natural energy of the gemstone.

  • The gem remains natural and effective for astrological purposes.

  • What really matters is that the gem is genuine, natural, and correctly recommended.
