Did you know most gemstones are treated? Learn about heating, oiling, dyeing, and fracture filling. Discover why treatment disclosure matters and how to ensure you're buying a 100% natural stone for astrology and investment.

When you admire the deep blue of a sapphire or the rich green of an emerald, you're witnessing nature's artistry—but sometimes, with a little help from human hands. Most gemstones on the market undergo some form of treatment to enhance their color or clarity. While some treatments are accepted, others can drastically reduce a stone's value and astrological efficacy.

Why Are Gemstones Treated?

Simply put, treatments make less-perfect stones more marketable. A pale, included ruby can be heated to achieve a vibrant red. A fractured emerald can be filled with oil to improve its clarity. These processes allow sellers to offer attractive stones at lower price points. However, for the discerning buyer—especially one seeking a gem for astrological benefits—knowing the treatment is crucial.

The US FTC Guidelines: Why Disclosure Matters

The US Federal Trade Commission (FTC) has clear rules to protect consumers. Sellers must disclose treatments if:

• The treatment is not permanent (it could fade or change over time).

• The treatment requires special care (the stone can't withstand heat or ultrasonic cleaners).

• The treatment significantly affects the stone's value.

Unfortunately, many sellers skip this vital step. That’s why buying from a certified gemologist, not just a jeweler, is essential.

A Closer Look at Common Gemstone Treatments

We classify treatments by degree, from mild (first-degree) to extreme (third-degree).

1. Heating (First-Degree Treatment)

• What it is: Exposing gems to high temperatures to improve color and clarity.

• Commonly Used On: Sapphires, Rubies, Tanzanite, some Quartz.

• Is it Acceptable? Heating is widely accepted in the trade as a stable and permanent treatment for certain stones. However, for astrological purposes, many purists prefer completely natural, unheated stones.

2. Oiling (First & Second-Degree Treatment)

• What it is: Filling surface-reaching fractures with colorless oil (like cedarwood oil) or colored oil.

• Commonly Used On: Emeralds.

• The Key Difference:

  • Colorless Oiling: This is a common and often-expected practice for emeralds to enhance stability and appearance. It's considered a mild, first-degree treatment.

  • Colored Oiling: This is used to deceive by altering the stone's color. It is a second-degree treatment and is not acceptable.

3. Dyeing (Second-Degree Treatment)

• What it is: Injecting colored dyes into porous or fractured gemstones.

• Commonly Used On: Turquoise, Jade, Lapis Lazuli, and sometimes fractured pearls.

• Is it Acceptable? No. Dyeing is deceptive and unstable. The color can fade easily. Dyed stones are considered ineffective for astrological use.

4. Fracture or Glass Filling (Third-Degree Treatment)

• What it is: Filling cracks with molten glass or lead-based substances. This dramatically improves the apparent clarity of heavily fractured stones.

• Commonly Used On: Rubies, often sold as "composite rubies."

• Is it Acceptable? No. These treatments are not permanent, are heat-sensitive, and significantly lower the gem's value and durability. They should be strictly avoided.

5. Waxing (Second-Degree Treatment)

• What it is: Coating a gemstone with wax to improve its luster and hide surface imperfections.

• Commonly Used On: Opaque stones like Turquoise and Coral.

• Is it Acceptable? For astrological stones, waxing is not acceptable as it alters the natural state of the organic material.

6. Re-construction (Third-Degree Treatment)

• What it is: Grinding low-quality material into powder and bonding it with resin to create a "new" stone.

• Commonly Used On: Turquoise and Coral.

• Is it Acceptable? These are not considered natural gemstones and are only suitable for costume jewelry. They hold no astrological value.

How Can You Be Sure? 2 Essential Steps for Buyers

1. Buy from a Specialist, Not Just a Jeweler: A certified gemologist has the training to identify treatments. A general jeweler may not have this specialized knowledge. At Shubh Gems, our team consists of certified professionals dedicated to gemology.

2. Always Demand a Reputable Lab Report: The single most important step is to get an independent certificate from a lab like IGI, GIA, or GRS. The report will explicitly state if a stone is natural and detail any detected treatments.
