The BuBo Impression

Many of our friends know that the traditional round brilliant cut is not particularly well-suited to concentrating colour.

And across the market, round brilliant diamonds are everywhere.

So we began to wonder:

What if we kept the overall impression of a round brilliant — but changed something? Could it deliver stronger colour, and become something more distinctive in the process?

So we actually tried.

The result is this decagonal diamond.

But honestly —

It doesn’t seem to have become more saturated.

At least on the question of colour, our little experiment didn’t quite yield the answer we were hoping for.

There is one thing, however, that did work —

It is genuinely different.

Compared to a traditional round brilliant, it carries more facets. Light enters and produces an extraordinarily rich, complex sparkle.

There are even moments when I find myself thinking:

Is this actually more brilliant than a round?

Of course, that could simply be our imagination.

So this time, we don’t want to draw any conclusions on its behalf.

If you find it as intriguing as we do, we’d love to hear from you:

Do you think it really outsparkles a round brilliant?

A Special Service | From Diamond to Your Jewellery

We want to offer you more than a beautiful stone. If you choose to have your BuBo coloured diamond set into a piece of jewellery, we’ll provide one complimentary original jewellery design — created specifically around this diamond and your vision.

We’ll start with the stone itself, and we’ll listen to you — the elements you love, the moments you want to remember, or even just a feeling you can’t quite put into words. All of it can become part of the design.

The design service is provided at no charge. Jewellery fabrication costs will be quoted separately based on the final confirmed design.

Lab-grown gemstones are created in a controlled environment using the same natural processes that form gemstones underground — just faster and without the environmental impact of mining. They are chemically, physically, and optically identical to mined gemstones, and are graded by the same standards. At LabGrownPro, every gemstone is ethically created, visually stunning, and offered at a fraction of the cost of mined alternatives.

We use standard Australian (AU/UK) ring sizing. To find your size, measure the inner diameter of a ring that fits well, or wrap a strip of paper around your finger and measure the length. Visit our Ring Size Guide for a full size chart, measurement tips, and international size conversions. If you are between sizes, we recommend choosing the larger size.
