You’ll find that each tunnel serves as a microscopic highway, allowing trapped inclusions to be altered or removed.
The laser’s controlled energy vaporizes material along its path, creating clean, precise channels that transform dark inclusions into translucent features.
Visual Impact: Before and After Laser Drilling Results
You’ll notice dramatic changes when comparing diamonds before and after laser drilling treatment.
Dark, distracting inclusions that once dominated the stone’s appearance become virtually invisible, while the diamond’s clarity grade can jump remarkably higher.
The enhanced light performance creates noticeably improved brilliance and sparkle that transforms previously unmarketable stones into visually appealing gems.
Inclusion Visibility Reduction
Before laser drilling transforms your diamond, dark inclusions can make even high-carat stones appear cloudy and unappealing, often relegating them to industrial use rather than fine jewelry.
When you choose to have your diamond laser drilled, microscopic tunnels strategically target these problematic inclusions. The process doesn’t completely remove dark inclusions, but it creates pathways that dramatically reduce their visibility.
You’ll notice the difference immediately as previously prominent flaws become virtually undetectable to the naked eye.
The transformation includes:
- Clarity enhancement – stones jump from lower clarity grades to near-clean appearances
- Brilliance restoration – light can now pass through areas previously blocked by inclusions
- Market value increase – treated diamonds typically see 30-40% value improvements
Your once-flawed diamond now sparkles with renewed brilliance and commercial appeal.
Clarity Grade Improvement
Although laser drilling creates only microscopic channels, the visual transformation in your diamond’s clarity grade can be nothing short of dramatic.
When a precise laser beam targets dark inclusions within your stone, you’ll witness a remarkable before-and-after difference. Previously unsellable diamonds with extensive visible flaws become marketable gems that appear much cleaner to the naked eye.
Your diamond’s clarity grade can jump considerably after treatment. The laser beam dissolves targeted inclusions, often elevating stones from lower clarity grades to higher ones.
This diamond’s clarity improvement translates to tangible value increases of 30-40%. What once appeared heavily included becomes a brilliant, sparkling gem with enhanced visual appeal.
The transformation allows previously flawed stones to regain their aesthetic desirability and commercial viability in today’s market.
