NILMANIK GEMSTONES – From Sri Lanka to the world

Our Story

NILMANIK Gemstones began with a simple promise: offer authentic Sri Lankan (Ceylon) gems with total transparency—from earth to artistry. We mine and hand-select rough, then cut and polish each stone with care so you can feel the story in the sparkle.

How it started

We are a family-run team from Sri Lanka with decades around mines, markets, and benches. What began as a passion for rough sapphires grew into a studio that polishes stories: stones for collections, engagement rings, and heirlooms.

“Every gem passes through our hands—so we can stand behind every carat.”

Responsible Sourcing

We buy directly in local markets and mines we know, paying fair prices and respecting the land. Most stones are heated only (a traditional and disclosed treatment); unheated pieces are labeled.

Verification & Reports

Need a lab report? We can arrange certification (e.g., GRS/GIA/IGI or local authorities) before shipping. Every listing states weight, dimensions, color, clarity, and treatment clearly.

Cornflower Blue Sapphire – Story #1

Cornflower Blue Sapphire · 1.05 ct

Found near [Area], this crystal showed silky inclusions under the loupe—a sign of potential velvety glow after a precision cut. We oriented the table to preserve color and spread.

Treatment: Heated · Origin: Sri Lanka · Clarity: Eye-clean

This rough came with a natural window. We closed it with a deeper pavilion, keeping the sea-blue tone and a lively return under daylight.
