{ "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "Is faint fluorescence okay in a diamond?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, faint fluorescence is usually fine and doesn’t affect a diamond’s sparkle or beauty. In fact, many experienced jewellers and valuers agree that a bit of fluorescence doesn’t take away from the quality. Strong fluorescence, on the other hand, can sometimes make a diamond look cloudy. But for most stones with faint or even medium fluorescence, there’s really nothing to worry about. As always, it’s best to see the diamond in different types of light before making a choice." } }, { "@type": "Question", "name": "Why do some diamonds glow under UV light?", "acceptedAnswer": { "@type": "Answer", "text": "Some diamonds glow under ultraviolet (UV) light because of tiny natural features in the stone, like traces of boron. This glow is called fluorescence, and it usually shows up as a soft blue colour. Around half of all diamonds show some level of fluorescence, but only a small number will actually look different in normal light. It’s a natural thing and doesn’t mean the diamond is fake or low quality." } }, { "@type": "Question", "name": "Does fluorescence affect the price of a diamond?", "acceptedAnswer": { "@type": "Answer", "text": "Fluorescence can affect price, but it depends on how strong it is and what the diamond looks like. Diamonds with strong or very strong fluorescence might sell for a bit less, especially if they’re very white (like D to F colour). That’s because strong fluorescence can sometimes make the diamond look a little hazy. But in lower colour grades (like G to J), a bit of fluorescence can actually help the diamond look whiter. In the end, how the diamond looks to the eye is more important than just the lab report." } }, { "@type": "Question", "name": "Should I buy a diamond with fluorescence?", "acceptedAnswer": { "@type": "Answer", "text": "There’s nothing wrong with buying a diamond that has fluorescence — especially if it looks good and suits your budget. Many buyers choose diamonds with faint or medium fluorescence because they offer great value and still look beautiful. Just make sure to look at the diamond under different lighting and check that it isn’t cloudy if the fluorescence is strong. If you're unsure, it’s always best to ask a trusted jeweller or gem expert for their opinion." } } ]}" />
