How to Read a Gemstone Lab Certificate

If you are planning to buy a gemstone, then you should also focus on its overall quality apart from its beauty. Especially if you are buying an astrological gem such as a ruby, emerald, or red coral, because the effectiveness of these gems depends mainly on their authenticity. The reason behind this is simple: natural gemstones preserve their innate healing energies. While heavily treated or synthetic gems lack such properties. 

Due to this reason, it is necessary to get your gemstone checked from a reputed gemstone lab such as IGI, GSI, GTL, or ITLGJ before buying. These gemstone certificates provide you with peace of mind that the gem is completely natural and genuine. But many people don’t know how to read a gemstone certificate properly. In this blog, we are going to give you the tips to read a gemstone lab certificate properly. 

What Is a Gemstone Lab Certificate?

A gemstone lab certificate is an official statement acquired from a recognized gemological lab. Before providing this certificate, these labs test the overall color, clarity, and durability of the gem with the help of various scientific tests and equipment. After this, these labs issue a certificate, which clearly states the gemstone's origin, color, clarity, and carat weight. 

In addition to this, it also tells whether a gemstone is artificially treated or enhanced or not. It also tells whether the gem is natural or synthetic. It must be noted that certification of a gemstone is essential for astrological gems such as ruby, yellow sapphire, red coral, blue sapphire, pearl, and hessonite. Because, as per Vedic astrological scriptures, only a natural and untreated gem provides the best astrological effects to the wearer. 

Why Gemstone Certification Is Important

The gemstone market contains many treated and synthetic stones that may look identical to natural gems. Without certification, it becomes difficult for ordinary buyers to identify the real quality of a gemstone.

A certified gemstone provides confidence, transparency, and trust. It also increases the resale value and credibility of the gemstone. Below we have listed some of the main benefits of a gemstone certificate:

• It helps to confirm whether the gemstone is natural or synthetic
• It reveals gemstone treatments and enhancements
• It provides accurate gemstone details
• Protects buyers from fake stones
• Increases trust and authenticity
• Helps in astrological gemstone selection

A gemstone certificate is like an identity card for the stone.

Important Details Mentioned in a Gemstone Certificate

Every gemstone laboratory follows a slightly different format, but most certificates contain similar information. Understanding these sections can help you read any gemstone report with confidence.

Name of the Gemstone

One of the first details mentioned in the certificate is the gemstone name. This confirms the exact variety of the stone.

For example:

• Natural Yellow Sapphire
• Natural Ruby
• Natural Emerald
• Natural Blue Sapphire
• Red Coral

This section is important because many gemstones resemble each other visually.

Natural or Synthetic Origin

This is one of the most important parts of the certificate. It tells whether the gemstone is natural, synthetic, or imitation.

Natural Gemstone

Natural gemstones are those gems that are formed under the surface of the earth or sea over millions of years due to extreme temperatures and pressure. 

Finding and mining such stone is extremely difficult. Due to this reason, they are being sold at high prices in the gemstone market. These stones are best for astrological purposes as well as for investment. 

Synthetic Gemstone

A synthetic gem is not a natural material; these stones are artificially created inside a laboratory with the help of artificial methods. Although they look similar to natural ones, they lack the astrological effectiveness.

Treatment Disclosure

Gemstone treatments are common in the jewelry industry. The certificate clearly mentions whether the gemstone has undergone any enhancement process.

Common Treatments Mentioned in Certificates

• Heat treatment
• Oil treatment
• Glass filling
• Dyeing
• Fracture filling
• Resin treatment

This section is extremely important because heavily treated gemstones may have lower astrological value and market price.

For example, an untreated yellow sapphire is usually considered more valuable than a heated one.

Understanding Gemstone Weight

Gemstone weight is measured in carats or ratis. The certificate will mention the exact weight of the stone. A gemstone of higher carat weight is more valuable than a gem. These prices increase even more if a gemstone has great color and clarity. Astrologers also recommend gemstone weight according to an individual’s horoscope and planetary condition.

Color Description

Color is one of the biggest factors affecting gemstone quality and price. A gemstone certificate usually describes the stone’s color using professional terms.

For example:

• Vivid Blue
• Pigeon Blood Red
• Golden Yellow
• Deep Green

Natural and evenly distributed color is usually considered more valuable.

Shape and Cut

The certificate also describes the shape and cut of the gemstone.

Common Gemstone Shapes

• Oval
• Cushion
• Round
• Pear
• Cabochon
• Emerald Cut

The shape affects both beauty and astrological suitability. For example, oval cabochon cuts are commonly preferred for red coral and cat’s eye stones.

Clarity and Transparency

Clarity refers to internal inclusions or imperfections inside the gemstone. Natural gemstones usually contain some inclusions, which are considered proof of authenticity.

A certificate may mention whether the gemstone is

• Transparent
• Translucent
• Opaque

Completely flawless gemstones are extremely rare and expensive.

Origin of the Gemstone

Some laboratory reports also mention the geographical origin of the gemstone.

For example:

• Ceylon (Sri Lanka)
• Burma (Myanmar)
• Kashmir
• Mozambique
• Italy
• Japan

Origin can greatly affect the gemstone’s value and desirability. For example, Ceylon yellow sapphires and Burmese rubies are highly prized worldwide.

How to Check if a Certificate Is Genuine

Nowadays, many gemstone dealers also provide fake gemstone certificates to their clients. These certificates look exactly like the original ones, but they lack the required information. 

Signs of a Genuine Gemstone Certificate

• Issued by a reputable gemological lab
• It contains a unique certificate number
• These documents have complete gemstone details
• They display a proper laboratory seal or QR code
• They match the gemstone physically

You should only buy the gems from a reputable gemstone seller like RashiRatanBhagya; they provide authentic certification.

• IGI
• GRS

You must note that certificates acquired from the above-mentioned labs are usually more reliable. In addition to this, these certificates are also internationally accepted.
