Full Article:
The journey of a Ceylon sapphire is remarkable—from deep within Sri Lanka’s ancient earth to your jewelry collection. Here’s how it happens.
Step 1: Traditional Mining
The Process: Sri Lankan gem mining is largely artisanal, using methods unchanged for centuries.
Miners work in small teams, often family operations:
- Identify gem-bearing gravel deposits (“illam”)
- Dig pits 5-30 meters deep
- Extract gravel in baskets
- Transport to washing sites
Traditional Practices: Many miners light candles and offer prayers before beginning work—a ritual passed down through generations.
Step 2: Washing and Sorting
The “Illam” Process: Gem-bearing gravel is washed in large wicker baskets:
- Water washes away mud and light material
- Heavier gems settle to the bottom
- Experienced sorters identify potential gems
- Rough stones separated by type and quality
The Skill: Sorters can identify sapphires, rubies, and other gems at a glance—even when covered in dirt. This expertise takes years to develop.
Step 3: Initial Evaluation
Assessment: Rough stones are examined for:
- Potential color when cut
- Clarity and inclusions
- Size and shape
- Treatment possibilities
Decision Point: Will this stone be:
- Cut and sold?
- Heat treated to enhance color?
- Sold as rough to collectors?
Step 4: Heat Treatment (Optional)
The Ancient Practice: Heat treatment has been used for over 2,000 years to enhance sapphire color.
The Process:
- Stones heated to 1,200-1,800°C
- Controlled atmosphere furnaces
- Typically 6-24 hours
- Permanent, stable results
Important: This is widely accepted and should always be disclosed.
Step 5: Cutting and Polishing
The Art: Master cutters plan each stone:
- Analyze the rough
- Determine optimal shape
- Mark cutting lines
- Execute the cut
The Process:
- Planning: Days or weeks studying the rough
- Sawing: Removing excess material
- Shaping: Creating the basic form
- Faceting: Cutting precise angles
- Polishing: Final brilliance
The Goal: Maximize color, minimize inclusions, create symmetry.
Step 6: Certification
