Do fake diamonds glow under UV light? Sometimes, yes. But glow alone does not tell you whether a diamond is real or fake. Stop guessing. Start saving. Get guided. Too many couples make expensive mistakes because they rely on internet myths instead of expert advice. You are not just buying a diamond ring. You are getting a master jeweller’s expertise.
I am Michael Dransfield, founder of Burgundy Bespoke Jewellers, and I personally guide you through every decision. Whether we meet in person in Brisbane, the Gold Coast, or the Sunshine Coast, or connect over Zoom anywhere else in Australia, you work directly with me. No jewellery shop. No sales team. No pressure. Just honest advice from someone who has spent over 50 years creating bespoke jewellery, from diamond engagement rings to wedding rings, earrings, and other pieces.
This guide will help you understand diamond fluorescence properly so you can choose with confidence when designing your engagement ring, wedding ring, earrings, or special gift.
Diamond Fluorescence Explained – Why Some Stones Glow Under UV Light
Fluorescence is a natural reaction that occurs when a diamond is exposed to ultraviolet light. This includes sunlight, nightclub lighting, and gem testing lamps used by jewellers.
Around 25 to 35 percent of natural diamonds show some degree of fluorescence. The most common glow is blue, but some diamonds can emit white, yellow, or green light. This happens due to trace elements inside the carbon crystal structure.
Fluorescence is graded on diamond certificates issued by respected laboratories such as GIA and IGI. The scale ranges from none to very strong. This information appears alongside cut, colour, clarity, and carat.
Fluorescence is not a flaw. It is simply a characteristic, just like shape or polish. Many high-quality diamonds, whether natural, lab-grown, si1 grade, or others, glow under UV light and look stunning in normal conditions.
When you’re ready to find the right diamond, my role is to add genuine guidance and clarity to every decision you make. Whether you’re choosing a round cut diamond for an engagement ring, a princess cut diamond for wedding rings, an asscher cut diamond for necklaces, refined diamond earrings, or bespoke rings, I personally help you assess si1 clarity, the ideal shape, and overall value so your new piece of jewellery feels just right.
Think of our process as a private, one-to-one shop experience without a shopfront – you work directly with me, Michael, and I guide you through certified diamond options (GIA and IGI) while keeping your secret proposal truly secret if needed. If you’re searching for meaningful gifts or a standout gift that lasts a lifetime, I’ll help you design something handcrafted, personal, and completely yours.
Does a Glowing Diamond Mean It’s Real? The Truth Buyers Often Get Wrong
This is where most people get confused.
A glowing diamond does not mean it is fake.
A diamond that does not glow is not automatically real.
Both natural diamonds and lab grown diamonds can fluoresce. Some genuine stones glow, some do not. UV light alone cannot tell you the origin or value of a diamond.
The only reliable way to confirm authenticity is through professional diamond testing and certification from trusted laboratories like GIA and IGI. This is why I always help clients review certificates properly during our consultations.
Some simulant stones can glow very strongly under UV light. They often emit unnatural colours or look chalky. That is why relying on torch tests or social media tips can lead to disappointment when buying loose diamonds online.
Choosing the right diamond shouldn’t feel like guesswork. My role is to add real-world insight and practical clarity so you can confidently find the stone with the perfect cut, colour, clarity, and carat weight that suits your story, whether it’s for an engagement ring, a wedding ring, bespoke rings, or timeless diamond earrings. From comparing a round cut to another shape, to understanding what an si1 grade truly means in real life, I walk you through every detail before you commit to a new piece of jewellery.
Think of this as your personal, behind-the-scenes shop of knowledge – where you get expert guidance without pressure. And if you’re exploring thoughtful gifts or searching for a meaningful gift that stands out, I’ll help you create something handcrafted, personal, and designed just for you.
Why Some Fake Diamonds Glow – And How to Avoid Costly Mistakes
Some imitation diamonds glow because synthetic materials react strongly to ultraviolet light. The glow itself is not the issue. The problem is how buyers interpret it.
Fake stones often show:
- Very bright green or yellow fluorescence
- Patchy or uneven glow
- Oily-looking surfaces
- No valid certification
The biggest mistake people make is buying diamond jewellery without expert guidance. Other websites sell you a diamond and a setting. I make sure you get the right diamond in the perfect setting for your budget.
During our consultation, I show you three to five diamonds within your range and explain exactly why one offers better value. No pressure. No pushy sales. Just clear education.
Avoiding costly mistakes starts with having the right guidance. My job is to add practical insight and genuine clarity so you can confidently find quality jewellery without second-guessing your choices. Whether you’re comparing different cut styles, deciding on a round versus another shape, or exploring what an si1 grade actually means in real life, I walk you through every detail.
Instead of a traditional shop experience, you get one-on-one support focused on what works best for you, especially when creating new bespoke rings or other pieces of jewellery. And if you’re searching for thoughtful gifts or the perfect gift to celebrate a milestone, I’ll help you design something handcrafted, personal, and built to last.
Lab-Grown vs Natural Diamonds Under UV Light – What Actually Matters
Both lab grown diamonds and natural diamonds can fluoresce. The glow does not tell you how the stone was created.
Natural diamonds form through mining over billions of years. Lab grown diamonds are created using advanced technology that replicates nature. Chemically and visually, they are identical.
Both can be cut into round, princess cut, oval, emerald, pear, radiant, marquise, asscher, and heart shapes. Both can sparkle beautifully in an engagement ring, diamond earrings, watches, and other pieces of jewellery.
What really matters is:
- Your values
- Your budget
- The look you love
Some clients prefer to add natural stones for their rarity. Others choose lab grown diamonds for ethical reasons. I help you compare both options side by side so you can make an informed choice.
Choosing between lab-grown and natural stones is about what feels right to you. My role is to add perspective so you can confidently find the option that aligns with your values, budget, and style. Whether you’re planning new bespoke engagement rings or wedding rings, comparing a round cut to another shape, or deciding if an si1 grade suits your lifestyle, I guide you through the differences in a clear, practical way.
Instead of a traditional shop visit where they add unneeded pressure, you receive personalised support focused on education. And if you’re searching for thoughtful gifts or a meaningful gift to celebrate a milestone, I’ll help you create handcrafted jewellery that feels truly personal.
Will Fluorescence Affect Your Diamond’s Beauty or Long-Term Value?
In most cases, fluorescence does not negatively affect beauty or value. In fact, medium blue fluorescence can make near colourless diamonds appear whiter in sunlight.
Only in rare cases of very strong fluorescence can a diamond appear hazy. This is something I check carefully before recommending any diamond for your bespoke jewellery.
What truly affects value long-term is:
- Cut quality
- Colour
- Clarity
- Carat weight
- Certification
- Craftsmanship of the setting
Fluorescence alone should never determine whether you buy or reject a stone.
Fluorescence is just one small part of a much bigger picture. My role is to add an expert perspective so you can focus on what truly matters when choosing new jewellery that lasts. From assessing a round cut diamond to exploring a different shape, and understanding how an si1 grade performs in everyday wear, I look at the full combination of factors that protect long-term value.
This isn’t a traditional jewellery shop experience – it’s a personal consultation where we design bespoke engagement rings, wedding rings, and other pieces of jewellery based on quality, not hype. And if you’re considering meaningful gifts or a memorable gift for a special occasion, I’ll help you create something handcrafted, considered, and built to endure.
Common UV Diamond Myths Debunked by Expert Jewellers
Many online myths confuse buyers:
- Fluorescence means fake
- Strong glow equals poor quality
- Only lab grown diamonds glow
- UV light is a reliable test
None of these statements is true. Fluorescence is just one characteristic. The real risk is misinformation.
Misinformation can be costly, which is why my focus is to add reliable guidance you can trust. Instead of guessing based on online myths, I help you understand how factors like cut, round versus alternative shape, and what an si1 grade truly means in real-world wear all come together.
This isn’t a typical shop environment – it’s a one-on-one conversation designed to give you clarity before you invest in fine jewellery. And whether you’re selecting a thoughtful gift or planning meaningful gifts for someone special, you’ll know every choice is backed by expert insight rather than internet rumours.
My Simple 3 Step Diamond Selection Process
- Discover: We talk through your vision, budget, timeline, and whether you need help keeping the proposal a secret.
- Select: I show you a curated selection of diamonds, whether natural, lab-grown, si1, or more, from my online platform that connects directly to diamond dealers. This saves clients around 15 to 20 percent compared to retail pricing. We review certificates and compare values.
- Create: Your bespoke engagement ring, wedding ring, or other piece of jewellery is handcrafted to perfection. Bespoke engagement rings and wedding rings take approximately four weeks to complete.
This three-step process is designed to add certainty and remove guesswork from start to finish. By the time we review options together, you’ll clearly understand how a round cut diamond performs, what an si1 grade offers in real terms, and why certain diamonds represent better value than others.
Rather than a traditional shop setting, you work directly with me through a structured, transparent process that keeps everything streamlined and discreet. And whether the end result is a meaningful gift or one of life’s most important gifts, each decision is made with intention, care, and long-term confidence.
Why Working With Me Is Different
I am not a traditional jeweller with a shop front or stock to try on. Everything I create is bespoke. There is no range. No display cases. No mass production.
You work directly with me from start to finish. I design what you want, not what I need to sell.
Consultations are available:
- In person in Brisbane, Gold Coast, Sunshine Coast
- Via Zoom Australia-wide
Jewellery designs are viewed during your consultation. Every piece is customer-led and handcrafted.
In the unlikely event of a manufacturing fault, I stand by my craftsmanship and will ensure it is put right.
The difference comes down to focus and accountability. By working directly with me, I can add depth to every decision, from assessing how a round cut will perform to explaining the real-world impact of an si1 grade.
Because everything is bespoke, each detail is shaped around what you want, not what’s sitting on display. That level of involvement matters most when the piece is a significant gift, where quality, trust, and craftsmanship can’t be compromised.
The Difference Expert Guidance Makes
Fluorescence is just one small part of choosing the perfect diamond. You need to consider cut, colour, carat, and clarity – especially if you’re comparing an si1 stone to other grades. The real goal is creating a ring or other piece of jewellery that feels meaningful, fits your budget, and lasts a lifetime – whether it’s for an engagement, a wedding, or a once-in-a-lifetime gift.
