Our In-House Gem Lapidary
Where Sri Lankan Gemstones Become Exceptional
At CeylonBlue, our journey does not end when a gemstone is sourced. It continues in our own in-house gem lapidary in Ratnapura, Sri Lanka — the City of Gems, where natural gemstones are carefully transformed through skilled craftsmanship, precision cutting and meticulous polishing.
Our Ratnapura lapidary gives us greater control over the journey from rough gemstone to finished gem, allowing our team to evaluate each stone individually and develop a cut that brings out its natural beauty, colour, brilliance and character.
From Rough to Refined
Every gemstone has its own personality. The cutter’s role is to understand the rough, work with its natural characteristics and make thoughtful decisions about shape, proportions, facets and finish.
Our in-house process can include:
Rough Gemstone Evaluation
Each rough stone is carefully examined to understand its colour, inclusions, crystal structure, potential yield and cutting possibilities.
Professional Inspection
Gemstones are assessed using appropriate gemological instruments to help determine the best approach before cutting begins.
Preforming
The rough is carefully shaped to establish the foundation for the final design while balancing weight retention, colour and optical potential.
Precision Faceting
Our skilled cutters work with carefully considered proportions, facet alignment and symmetry to maximise the gemstone's visual performance.
Fine Polishing
Each facet is progressively refined and polished to achieve a clean, bright and highly reflective surface.
Quality Control
Finished gemstones are examined for symmetry, meet points, facet definition, polish, proportions, girdle finishing, brilliance and overall presentation.
Master Cutting from the City of Gems
Ratnapura has been at the heart of Sri Lanka's gemstone industry for generations. Our own lapidary connects CeylonBlue directly to this remarkable gemstone heritage.
Working close to the source gives our team an important advantage: we can evaluate rough material, plan the cutting process and develop finished gemstones with a clear understanding of the stone from the beginning.
From traditional Sri Lankan cutting knowledge to contemporary precision techniques, we combine craftsmanship, creativity and precision to create gemstones designed for today's jewellery makers, collectors and discerning clients.
Cutting for Beauty, Not Simply Weight
A fine gemstone is not created simply by removing material from rough.
The objective is to find the right balance between colour, brilliance, scintillation, proportions, symmetry and weight retention.
For every stone, our cutters consider questions such as:
- How can the natural colour be presented at its best?
- Where should the table and crown proportions be positioned?
- How should the pavilion be designed for efficient light return?
- How can symmetry and meet points be refined
- How can the cut preserve valuable weight without compromising beauty?
- How should the gemstone's natural characteristics influence the final design?
This approach allows us to create gemstones that are not merely polished stones, but carefully considered pieces of gemstone craftsmanship.
For your peace of mind, we offer gemstones with independent gemmological certification.
A certified report confirms:
- Authenticity (Unheated or GIA Approved Heated)
- Treatment status
- Gemstone characteristics
* Certification is essential for trust, value assurance, and long-term investment confidence.
