Authentication & Certification
Every Gemstone Certified by World-Renowned Laboratories
GIC Certification
Established in 2005 as a subsidiary of the prestigious B P de Silva Group (a name synonymous with luxury since 1872), the Gemological Institute of Colombo (GIC) is one of Sri Lanka's most respected private laboratories. GIC combines over 150 years of family heritage in the gem trade with cutting-edge scientific analysis to protect both the buyer and the seller.
Advanced Technology for Absolute Certainty
GIC is at the forefront of gemological innovation in Sri Lanka. Their laboratory in Colombo is equipped with international-standard analytical tools, including:
- FTIR Spectroscopy: Used to create a "molecular fingerprint" of a gemstone, allowing for the precise detection of heat treatments and synthetic origins.
- UV-Vis-NIR Spectroscopy: Assisting in origin determination and the identification of subtle color-enhancing treatments.
- LIBS Testing: A high-energy laser technology used to detect chemical elements like Beryllium, ensuring that our sapphires have not been artificially diffused.
CIGS Certification
The Ceylon Institute of Gemological Sciences (CIGS) stands as a premier institution dedicated to the advanced study and scientific analysis of gemstones. Based in the heart of Colombo, CIGS is unique because it functions both as a high-level educational body and a state-of-the-art gemological laboratory, ensuring that every report is backed by the latest academic research.
The CIGS Scientific Advantage
At Ceylon Gem Book, we utilize CIGS for their uncompromising commitment to scientific accuracy. Their laboratory is staffed by gemologists who are often at the forefront of identifying new treatments and origin characteristics.
- Academic Rigor: CIGS reports are known for their technical depth, providing a level of detail that satisfies even the most analytical international collectors and investors.
- Advanced Spectroscopy: Utilizing high-end technology like FTIR and EDXRF, CIGS provides a "molecular scan" of each stone to detect trace elements, ensuring that your sapphire's "Natural" and "Unheated" status is scientifically proven.
-
Expert Origin Attribution: Because CIGS is deeply rooted in the gem-rich soil of Sri Lanka, their gemologists possess an unrivaled "eye" for identifying the specific internal characteristics of Ratnapura-mined stones.
GUILD Certification
Founded in Los Angeles in 1980, GUILD is a global leader in colored gemstone identification and origin determination. With a state-of-the-art laboratory right here in Beruwala, Sri Lanka, GUILD provides our clients with advanced scientific testing—including LIBS and LA-ICP-MS—to detect treatments and confirm the natural, unheated status of our finest sapphires. Their 'Colored Gemstone Cutting Report' ensures that the precision and brilliance of our stones are documented to the highest international standards
GRS Certification
Founded in 1996 by Dr. Adolf Peretti, GRS is an independent Swiss laboratory that has become the most respected name in colored gemstone reporting. For a collector, a GRS certificate is not just a document—it is a global "passport" that ensures the stone's value is recognized by every major auction house and elite jeweler from Geneva to Hong Kong.

About Ceylon Gem Book: Where Rarity Becomes Legacy
Our Heritage
Deep within the legendary valleys of Ratnapura, Sri Lanka—the fabled "City of Gems"—lies a heritage that has spanned centuries. For generations, this soil has yielded the world's most coveted treasures: the Royal Blue Sapphire, the sunset-hued Padparadscha, and the crystalline brilliance of the Ceylon yellow sapphire.
Ceylon Gem Book (CGB) was born from a desire to share this heritage with the world, moving beyond the traditional barriers of the trade to offer a transparent, "open-book" path to gemstone acquisition.
The "Open Book" Philosophy
In an industry often clouded by complexity, we believe in radical transparency. Every gemstone tells a story—from its formation deep within the earth to its discovery by local miners. At Ceylon Gem Book, we document that story.
We provide our global clientele with more than just a stone; we provide a curated path to legacy. This means:
- Direct-from-Source: Eliminating unnecessary middlemen to provide value and authenticity directly from the mines of Ratnapura.
- Absolute Certification: We refuse to trade in unverified stones. Every significant gem is accompanied by a top-tier laboratory report (GIC, GRS, or GGL).
- Unheated & Natural Focus: While we appreciate all of nature's beauty, our specialty lies in natural, unheated stones—the rarest 1% of the world's production.
A Global Sanctuary
Based in Sri Lanka but serving a global sanctuary of collectors, investors, and jewelry connoisseurs, we have mastered the logistics of rarity. From New York to London, Tokyo to Melbourne, we ensure your treasure is delivered with full insurance and door-to-door security.
Our Promise
Whether you are a seasoned investor looking for an investment-grade sapphire or a couple seeking a bespoke engagement stone, our mission is the same: To ensure that the rarity you acquire today becomes the legacy your family treasures tomorrow.
"We don't just sell gemstones; we help you write the next chapter of your family's heritage."
