Designing Beauty at the Atomic Scale

Recently, I had the chance to sit down with gemmologist and materials engineer Mubashir Mansoor, whose work lies at the remarkable crossroads of physics, materials science, and gemology. Our conversations quickly went far beyond gemstones themselves, challenging the way we think about beauty, value, and even the idea of perfection in jewellery.

I met Mubashir in 2024 at Jewels Talk in Sri Lanka, an inspiring educational forum held alongside the annual Jewels international gem and jewellery trade exhibition, organized by the Gemmologists Association of Sri Lanka (GASL) who kindly invited us both to speak at their event. The event brings together local and global experts to exchange ideas on emerging industry trends, ethical practices, responsible gem sourcing, and evolving technologies shaping the future of jewellery.

I had the privilege of sharing my journey of founding Sippi, along with our vision for what jewellery can represent beyond aesthetics.

What truly connected Mubashir and me, though, was a shared belief in creating something meaningful, something that goes beyond objects or trends, and instead carries purpose, story, and impact. 

Since that first meeting, we’ve stayed in touch, exchanging ideas, challenging each other’s thinking, and exploring where our paths might one day align. Our conversations haven’t just been about if we could collaborate, but about how and what opportunities might eventually bring us to work on something meaningful together.

What I love about Mubashir is how he sees things differently, not just gemstones, but ideas, challenges, and possibilities. He has this mix of deep knowledge, curiosity, and a genuine sense of awe for the world. He’s positive, humble, and funny, even with all he’s achieved, and he’s always ready to help bring something new into being. 

One of the first things I asked Mubashir was simple: What do you see in a gemstone that most people don’t?

Defects.

In the jewellery world, people often talk about perfection, clarity, flawlessness, purity. But from a scientific perspective, the tiny irregularities inside a crystal structure are actually what make gemstones beautiful.

These “defects” are what give gemstones their colour and character.

For example, ruby gets its deep red colour because small amounts of chromium replace aluminium atoms in its crystal structure. Without those tiny disruptions, ruby would actually be colourless.

As Mubashir explained to me:

“The most perfect gemstone is actually the most imperfect one.”

For a materials engineer, these imperfections are not problems to remove. They are features that can be studied, understood, and sometimes even controlled. Through techniques like heat treatment or controlled crystal growth, scientists can enhance certain characteristics within a gemstone.

In a way, they are shaping beauty at the atomic level. 

One thing that became very clear during our conversation is that Mubashir doesn’t see science and art as separate worlds. To him, they are deeply connected.

The elegance of a scientific theory or the symmetry of a crystal structure can be just as beautiful as a painting or sculpture. Jewellery becomes a natural meeting point between these two disciplines, science shaping the material, and art shaping how that material is expressed.

As he described it:

“It’s a waltz of disciplines, physicists, designers, artists, engineers. When they come together, that’s when real masterpieces happen.”

This idea resonates strongly with us at Sippi Jewellery, where design often grows from collaboration between artisans, cultures, and different creative perspectives.

Another topic that often sparks debate in the jewellery world is the question of natural versus lab-grown gemstones. So I ask him about his views on these two types of gemstones. 

He tells me that these two categories shouldn’t be seen as competitors. They simply tell different stories.

Natural gemstones are geological miracles formed over millions of years deep within the earth. Lab-grown gemstones, on the other hand, are the result of human innovation and scientific progress.

Chemically and structurally, both are real gemstones. What changes is their origin.

Natural stones often carry emotional and historical significance, making them ideal for heirloom pieces.

Lab-grown gemstones open new possibilities for design. Because they can be created in controlled environments, scientists can experiment with colours, optical effects, and properties that are sometimes difficult to find in nature.

Rather than replacing natural gems, they expand the creative landscape for designers. At the same time, they prompt us to reflect on the origins of what we value, natural gemstones that are finite resources, formed over millions of years and deeply woven into the cultural narratives of the communities they come from. Recognising this connection matters, because it shapes how we value, use, and ultimately respect these materials.

Have you ever wondered how culture shapes our perception of gemstones? I have always been keen to understand the impact of culture, how it gives these materials meaning, and why that meaning is essential to their continued relevance and preservation.

Gemstone preferences are rarely random. Different regions have developed strong relationships with certain colours and stones over centuries.

In parts of the Middle East, green gemstones carry deep cultural meaning. In regions influenced by Buddhist traditions, yellow stones are particularly valued. Blue gemstones have long held symbolic importance in Western jewellery traditions.

These preferences reflect history, spirituality, and cultural storytelling.

For designers, understanding these cultural layers opens up new possibilities. Jewellery becomes not just a design object, but a bridge between traditions.

We also spoke about something that often gets overlooked in the industry, the people behind the gemstones.

Many stones are mined in one country but cut, polished, and sold somewhere else. As a result, the economic value of the gemstone often moves far away from the communities where it originated.

Supporting craftsmanship within producing regions can help preserve local skills and create stronger, more sustainable economies.

For anyone buying jewellery, Mubashir suggests asking a few simple but important questions:

Where was this jewellery made?  Who crafted it?  Did the process benefit the community where it came from?

These are questions that shift the focus from simply buying an object to understanding the story behind it.

Beyond gemstones, Mubashir’s work extends into advanced materials engineering across several industries, including pharmaceuticals and laser technologies.

Mubashir and his two sisters recently launched their business https://www.stemzy.org/  Stemzy Engineering Solutions, a technology and materials research company registered in Istanbul

His company develops computational models and experimental processes to design materials with specific properties, sometimes at the atomic scale.

The long-term vision is to build a research-driven ecosystem where scientific discoveries lead to new technologies, spin-off companies, and opportunities for future innovators.

Yet despite this broad work, gemstones remain close to his heart.

They are not just scientifically fascinating, they are joyful.

As he put it during our conversation:

“At our core, we’re defect engineers. Wherever there are materials, we try to contribute in some small way.”

Speaking with Mubashir reminded me that jewellery sits at a very unique crossroads. It connects science and art, nature and human creativity, heritage and innovation.

And sometimes the most interesting discoveries happen when people from completely different disciplines start talking to each other.

At Sippi Jewellery, we’re excited to continue this dialogue and explore future collaborations that push boundaries while still respecting tradition.

Because in the end, the beauty of gemstones, much like the beauty of ideas, often lies in the imperfections that make them unique.
