D with strong blue?

[clearfading]

Hi all,
I saw a nice looking around 1 ct rose cut but it is a D with strong blue. Any opinions on this? They offer 3 day inspection. What negative effects would I be looking for?
Should a D with strong blue just be avoided?
Thanks!

Ask the seller if it has any adverse reaction in bright sunlight due to the Strong Fluor.
You would look for an oil look on the stone. It may look bright blue in sunlight which may
or may not bother you. Not how sure this really looks with a rose-cut stone.

HI! i have a D with medium blue and I LOVE it. I only notice blue flashes in bright sunlight. I think that the crispness of the D color paired with the chunky facets (it's an OEC) look amazing. But i wanted blue fluorescence. It's the clearest diamond i've ever had. I have several diamonds with no flour and I can say I like the diamond with flour better.

I had a D color RB w sbf, and it did get a tad oily, but not in a bothersome way. I have an E color EC w sbf, and it is crystal clear

I could very well see it being as a positive in a rose cut.
I think that has to do with how much skin is seen thru the rose itself when worn, to make that choice tho.
would the strong blue negate that at times?
Curious!

The main thing is that you'll want to make sure the diamond isn't cloudy or milky looking in any light. The only time you might see any hint of blue would be in direct sunlight, and it looks super gorge in my opinion! My antique stone is D with strong blue fluoro, and there are zero negative effects!

I love fluorescence! Mine is E with sbf and I’m having another ring made with E and sbf - not intentionally but I just loved the stones.

 

[rainydaze]

I have a D with mbf and it's gorgeous. No milkiness or haze, which is what you would want to ask about/look for.

 

[Redwoods-hiker-girl]

I have a D, two E's, and an F MRB with SBF. I bought them *because* of their SBF! They're beautiful, and the SBF has no negative effect on any of them.

The negative may be that dealers, not consumers, find strong fluorescence a potential haggling point and work the value downward because they can. It is business, not beauty they haggle over. Dealers often refuse to purchase diamonds with so much fluorescence. Most consumers seem to limit the amount to medium or less. Some contrarian consumers like the risk or the potential for some visual excitement of medium to very strong fluorescence. Dealers tend to follow the path of what sells the fastest without a big argument over the price. They prefer to buy and sell the least problematic diamonds and to get the highest rate of inventory turnover.

I love the fluorescent diamond I wear all the time, but it is not the type of diamond easily sold or loved by most diamond dealers. The safest bet is a diamond with minimal UV reaction, but when someone likes "different stuff", then the UV reaction can be highly attractive. It has to do with personality as much as beauty.

Isn't there some term for colorless diamonds with SBF? I can't think of it right now but I swear I've seen it before.

DROOL!! My dream stone...antique Asscher

 

[bright&shiny]

My ER has SBF - and no ill effects at all. You definitely need to check, though. I've seen some fairly cloudy stones in the sunshine....

Google says they used to be called blue-white when they were sought after, before fashion turned around and decided fluoro was bad. It also appears to coincide with a 1938 FTC ruling against the term for some reason. In 2020, a company called Fire and Ice Diamonds look to have tried to revive the concept https://www.prnewswire.com/news-rel...duces-the-blauweiss-collection-301179856.html.
Overblues where they’re negatively affected by the VSBF and are milky and oily appear to be very rare going by the comments of the aficionados for those stones here!

Some of the blue seen in diamonds outside on a sunny day will be just reflections from the huge blue sky.
You'll see this equally in all diamonds regardless of the amount of fluorescence they have.

So, if possible, I'd evaluate this diamond right next to one with no fluorescence.
Then you'll know what blue comes from sky reflections, and what blue is from the fluorescence.

Just saying.

 

[oldminer]

In the 1950s and 1960s, diamonds with D-F color and strong blue UV fluorescence were often referred to as Premier diamonds. There was a mine in South Africa named the Premier mine, and a good number of colorless range fluorescent diamonds came out of that pipe.

"Blue-White diamonds" was terminology to describe colorless diamonds and also the very rare, slightly blue-tinted diamond. The blue might have been the body color or blue fluorescence. The term was usually far more widely applied than what was ethically reasonable.

Retailers and dealers offered blue-white down to H color or described almost all their diamonds with the term. Since it was so often abused, the FTC regulated the terminology virtually out of existence. Only diamonds that have a slightly blue tint and an almost colorless body color can be said to be blue-white, and so very few are that way; it has become dead terminology by default.

 

[PearCraze]

I had a SB fluoro, D color pear, and it was beautiful. I notice that all of my diamonds regardless of strength of fluorescence would look a little hazy in Super strong mid summer sun. The rest of the year outdoors they were just a hint of blue, and glorious sparkle. When I tried to sell my diamond though, it was definitely something that was an issue, since the jeweler has to consider that they will have trouble selling it to the general public.

I ask people never to look at a diamond in direct sunlight.
The results are counter intuitive and it serves no purpose.

Use shaded sunlight or cloudy day light, but never direct sunlight. Please.

I also find direct sunlight to be unflattering to a diamond, well or poorly cut
