Negligible or Strong Blue Fluorescence, I-color diamond

Negligible or Strong Blue Fluorescence, I-color diamond

“I’m trying to decide between this 1.705 carat, I-color, VS-2 clarity, Brian Gavin Signature round diamond with negligible fluorescence, and this 1.721 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond with strong blue fluorescence. The higher clarity diamond is almost $2500 cheaper! Is blue fluorescence in an I-color diamond bad? Why is the diamond with negligible fluorescence so much more expensive? Please help me decide whether I should go with negligible or strong blue fluorescence in an I-color diamond. Thank you.”

Negligible vs Strong Blue Fluorescence in I-color diamond:

brian-gavin-signature-agsl-104078383018-strong-blue-fluorescence-i-color-diamondI can appreciate you might be confused about the affects of strong blue fluorescence upon the price of this 1.721 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond, since you would think that a higher clarity diamond with the same overall cut grade of AGS Ideal-0 would cost more than a diamond of the same approximate carat weight, color, and lower clarity grade. In this instance the strong blue fluorescence is going to benefit you in two ways, in the form of a discount, and possibly improving your perception of color.

Strong blue fluorescence in an I-color diamond is likely to make the diamond appear to be whiter, when the diamond is viewed in lighting environments that contain a high volume of ultra-violet (UV) light. This is because the ultra-violet light will excite the blue fluorescent molecules, which will then help to filter out some of the yellow.

The discount applied to diamonds with blue fluorescence actually has nothing to do with how fluorescence affects the visual properties of diamonds, but rather is the residual affect of an investment firm from Asia, deciding to preclude diamonds with fluorescence from parcels of diamonds that they were offering to clients for investment purposes in the late 1970’s.

The practice of not marketing diamonds with blue fluorescence for investment purposes, created a surplus of diamonds with blue fluorescence, because other investment firms also began to preclude diamonds with blue fluorescence from investment parcels of diamonds, so the industry responded by offering a discount on diamonds with blue fluorescence in an effort to make them more appealing to retail consumers… I don’t think they expected the discount to stick, but it continues to be applied to diamonds with blue fluorescence to this very day.

Which Brian Gavin Signature diamond should you choose:

Since both Brian Gavin Signature round diamonds have an overall cut grade of AGS Ideal-0, and are cut to the same range of proportions, and exhibit an exceptional degree of optical precision, the light performance of the 1.705 carat, I-color, VS-2 clarity, Brian Gavin Signature round diamond is comparable to that of the 1.721 carat, I-color, VS-1 clarity, Brian Gavin Signature round diamond that exhibits strong blue fluorescence.

Thus the decision whether to buy one Brian Gavin Signature round diamond over the other, really comes down to how you feel about blue fluorescence. Obviously the strong blue fluorescence has some benefits, but not everybody appreciates knowing that their diamond is going to glow bright neon blue when it is exposed to black light; although personally I find that characteristic of blue fluorescence to be quite intriguing and beautiful.
