The Koh-i-Noor Purity Benchmark, Reimagined by Limelight Lab Grown Diamonds
The story of the Koh-i-Noor started back when diamonds were appreciated without any fancy grading systems. People simply looked at size, clarity, and that special sparkle and purity. If we put that old idea of “purity” into today’s diamond terms, it matches the kind of super clean, low-impurity diamond we now call Type IIa.
Type IIa diamonds are pretty rare in nature and really stand out when they’re well cut. People have always loved them, especially royal treasuries and jewellery collectors, because they look amazingly clear in natural light.
Modern buyers, however, want more than just a legend. Today, people are moving toward utilitarian jewelry - pieces that transcend time and adapt to movement. Especially brides today; they are not just selecting bridal jewellery for the big day but choosing pieces that fit their budget, are versatile, and suit the occasions they plan to wear them.
This shift is exactly where Type IIa (2A) diamonds come in. Known for their exceptional purity and brilliance, they align perfectly with the needs of modern consumers, helping you make an informed, future-ready choice that’s as practical as it is timeless.
Understanding Different Types of Lab Grown Diamonds: Ia, Ib, IIa & IIb Diamonds
Here is a quick look at the other types:
- Type Ia (Type 1a)
- Type Ib (Type 1b)
- Type IIa (Type 2a)
- Type IIb (Type 2b)
This is the most common type (about 95% of natural diamonds). Small groups of nitrogen give it a soft look: almost clear or gentle light yellow.
These are very rare. Nitrogen atoms sit alone, so they shine in bright yellow, orange, or brown (people call them “canary” diamonds).
These are the purest diamonds (almost no nitrogen or boron at all). They look super clear and bright, mostly colorless, sometimes with soft pink, brown, or grey tones.
A tiny bit of boron makes them special. They can carry electricity and show lovely blue or grey-blue colors. They are extremely rare.
Each type helps show why every diamond feels so unique and beautiful.
How Lab Grown Diamonds Achieve Type IIa (2a) Purity Consistently
Type IIa (2a) diamonds are defined by the near-absence of nitrogen impurities, delivering exceptional clarity, transparency, and superior brilliance, qualities that elevate them to this rare grade (only 1-2% of natural diamonds qualify in the world)
This is how lab grown diamonds achieve Type IIa grade:
Most Type IIa lab grown diamonds use the Chemical Vapour Deposition (CVD) process. Carbon atoms deposit layer by layer in a controlled chamber, limiting nitrogen and boron impurities that cause colour and reduce optical purity in typical diamonds.

Type IIa Diamond Certification: How to Verify the Jewellery and the Report
If you are buying certified diamond jewellery, the goal is not to browse through the diamond jargon. The goal is to know what to check.
Use this short list:
- Ask what certification is provided for the centre diamond(s)
- Match the certificate details with what is shown on the product page or tag
- Check clarity and colour grades alongside the basics like carat
- Ask one direct question: “Where is Type IIa grade stated for this diamond?”
If the answer is clear, the buying experience feels calmer. That matters more than sounding technical.
Style with Purity: Type IIa in Modern Fine Diamond Jewellery
The reason Type IIa diamonds are mostly used in fine diamond jewellery is that today’s luxury is quiet. People want a clean look that holds up from desk-to-dinner meetings or day-to-night routine.
Type IIa diamond jewellery sits naturally inside that preference, especially when the design stays refined:
- Minimal chains and everyday pendants
- Crisp studs that look sharp without trying
- Stackable rings that still read premium
- Clean silhouettes that belong in luxury diamond jewellery without being loud
