Never understood the fascination with diamonds. Will not ever be buying one. |

Fortunately, I never had to. I inherited my grandmother's, which now sits on my wife's hand. It's quite beautiful. Nonetheless, the "diamonds" of this planet, if they exist, would be even dearer bought than the stones of the Kimberley pits. |

Diamonds can also form in the vacuum of space, at very low temperatures. This, in fact, is what labs are trying to reproduce right now, in the quest to make diamond circuit boards. Diamonds have some very odd, and very beneficial behavior aside from being super strong (actually, diamond is quite weak unless formed in a very specific manner as natural diamonds, and "space" diamonds are). Diamond for example, conducts heat/cold faster than any other material on earth. Blue diamond, is conductive (this is the holy grail of lab diamonds right now). A planet full of diamonds though means we don't have to pursue lab diamonds - we have an endless supply! Just need to get those anti-matter engines running, so we can get there in about 900 years. |

I was at my jewelers a couple of months back picking up something and my jeweler put a $167,000 4.5 carat diamond engagement ring on my finger. A Canadian diamond. That beat my last try-on of 3 carats. My hand was almost shaking with it on. So beautiful it was. Then she and I both laughed, like we always do, told each other we'd never have one, then moved on to the pearls. We joked saying that diamond would go to a 2nd wife, younger, blond, with implants. He'd be an oil guy in his 50s doin' Viagra. KB, I've seen quite a few colored diamonds; yellow, pink, cognac come to mind. They all can be quite stunning, and quite pricey; the right cut can really make a diamond sparkle. |

Blondie: Yeah, diamonds - especially colored ones are fascinating. Blue is from boron, introduced during the process of making the diamond, and is what makes some diamonds conductive. They're very rare, but very special indeed. I think the "Blue Hope" diamond is one of the most famous. While they're not at all rare, they are very tricky to create in the lab (at least to get the carbon to bond the way it does in natural diamonds, and not the way it does graphite), and have some really cool properties. You may see nearly everything made of diamond in the future - at least if the nano-tech guys have their way! Say goodbye to glass. |

I don't know what this means, maybe someone here can help. I inherited a diamond from my grandmother years ago, and had it appraised. The appraisal came back saying the stone had no detectable flaws, and included the notation: "strong blue fluorescence." Is this a good or bad thing? |

Fluorescence is not inherently good or bad. It just is, and many diamonds exhibit this property. A fluorescent diamond will glow a certain color under UV light (a black light). Also sunlight contains UV and compared to an identical diamond with no fluorescence yours may have a noticeable bluish look though it can be hard to be certain you are not just seeing reflections of the blue sky. Almost 100 years ago there was a scandal in which jewelers marketed what they called "Blue-White" diamonds at a premium. (Real blue diamonds are astronomically expensive.) When it was revealed they were not really blue, only fluoresced blue, the **** hit the fan. The government busted some people and fluorescence got a bad rap that it has yet to shake here in the USA. In Europe fluor is not seen in a negative way as it sometimes here is in the US. Also, people more knowledgeable about diamonds don't mind fluor; many even seek it out and enjoy it. Blue fluor can make white diamonds with lower color like J or K look less yellow in sunlight by a few grades. In the colorless grades like D, E or F fluorescence can lower the price a few percent. A very small percentage of the diamonds with strong or very strong fluo may look milky or oily in sunlight. When shopping avoid these stones. Fluorescence can appear in many colors, blue, yellow, green etc. The hope diamond is gray-blue but it fluoresces red. As you might guess a white diamond that fluoresces yellow will be less desirable than one that fluoresces blue. My asscher has Medium blue fluor and I'll post of pic of it under UV light. |

Plays I recommend you send your stone to GIA. You do not have to be a business to do so, but it must be removed from the setting. A reputable lab will only grade a loose stone. GIA is the gold standard for grading diamonds. Other labs like IGI or EGL will grade it more generously, but anyone without their head up their @ss knows their grades are bogus. It's a rip off that IMHO borders on fraud. Many people think GIA stones are more expensive - not true. They are just not graded dishonestly. Send the same diamond that EGL graded F VS1 to GIA and it may get the grades H SI1. Shocking, disgusting but true. ![]() BTW Blondie, I have four natural fancy colored diamonds. I'll start a thread. |

Plays it will cost you $154 to get your 2 ct diamond graded by GIA. A grading report from GIA is what any buyer will want - not an appraisal regardless of how reputable the appraiser is. Diamonds are expensive and their value varies tremendously with the color/clarity etc. Tiny variations that the novice could not detect can double or triple the value. You want to be as certain as possible that a diamond really really is the color and clarity claimed. GIA, or AGS, is as certain as you can get. http://www.gia.edu/lab-reports-services/fees_payment/lab_fees/USD_feeschedule_Diamond_081210.pdf GIA is in New York and Calif. You can drop it off personally if you don't like shipping. Then only other lab I'd consider is AGS in Las Vegas. |

Kenny's absolutely right about the blue diamond. A diamond's phosphorescence is very different from it having boron, which makes a blue diamond. As he said they're exceedingly rare, where most diamonds have some level of phosphorescence. I had no idea that was graded though in commercial diamonds - that's actually really interesting. Kenny - indeed you are the God of diamonds.

Phosphorescence is different from fluorescence. I think the former is giving off light after the light source is removed. The later is giving off a particular color when UV light is present and I think it has something to do with electrons changing valence levels. |

Kenny, Sorry - you're absolutely right. I read through your post and was thinking of a special on diamonds I had seen where they were showing the phosphorescent properties of diamonds. The two properties are related, but you're right - very different. Phosphorescence is the "delayed" emitting of that energy (as light) after being exposed to UV, vs. the immediate emitting of that energy in Flourescence just as you explained above. I guess I hadn't realized diamonds had both - so you've taught me something new - thanks. Edited by KlavierBauer, Dec 11 2010, 10:35 PM.
