What is E-beam gemstone enhancement?
E-beam treatment is a widely accepted, fully disclosed way of enhancing gemstone colour. The electron beam changes the colour of the stone from within - producing rich, vivid hues that are completely permanent, with no chemicals involved.
Unlike surface coatings or fillers, the colour becomes part of the gem itself. It doesn't fade, chip, or wash off - and the treatment is fully disclosed and accepted by international gem laboratories including GIA and IGI.
- No chemicals - clean, safe treatment
- Permanent colour - not a coating or film
- Accepted by GIA, IGI, and all major gem labs
- Fast turnaround, even on large lots
- Consistent, uniform colour across every batch
Colour depth is precisely controlled, then locked in with a gentle heat treatment - the same result, stone after stone.
Colour enhancement by stone type
Blue Topaz
Colourless or pale Topaz is transformed into vivid blue shades - from light Sky to deep London Blue. The colour is permanent and accepted worldwide.
Diamonds
E-beam treatment produces stable fancy colours in diamonds - yellows, blues, and greens - with full documentation for gem lab disclosure.
Quartz & Others
Quartz responds beautifully to E-beam treatment - green Prasiolite from Amethyst, rich Smoky tones, and stable Citrine colours.
From rough stone to vivid gem
Intake & assessment
Your stones are logged, weighed, and checked for suitability - clarity, existing colour, and condition - before any treatment begins.
