The BuBo Impression

Perhaps I should call it a Radiant Modified Cut?

Though in the end, the name hardly matters.

What is certain is this: it has eight clean, defined edges.

And I genuinely love this diamond.

Most of the time, I am not fond of the bowtie effect in coloured diamonds.

But this one is an exception.

Its blue is deep and luminous — and if you look closely, you’ll notice a very faint division running through the centre.

Strangely, this does nothing to diminish its beauty.

If anything, it reminds me of an hourglass — one that has been quietly recording time.

Light moves across both sides, and that subtle boundary in the middle feels like a mark left by time itself.

Perhaps because it is a blue diamond, the association becomes even more interesting.

If you’ve ever played League of Legends — when you look at this stone, does it remind you of something from the mage item shop?

We won’t say the name.

But we think you know exactly what we mean.

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.

To learn more about our design and custom jewellery process, please don’t hesitate to get in touch.

Frequently Asked Questions

To keep your LabGrownPro jewellery looking its best:

  • Avoid contact with perfume, cosmetics, chlorine, and perspiration
  • Gently wipe with a soft cloth after wearing

  • Clean occasionally with mild soapy water and a soft brush, rinse thoroughly and pat dry
  • Store S925 silver pieces in a sealed bag when not worn to prevent tarnishing

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.
