Today’s review on a signature hearts and arrows round diamond is going to help you cut out the hours spent trawling through jewelry stores to find the perfect stone. 

1.511 E Color VS2 Signature Hearts And Arrows

1.5 carats diamond hearts and arrows review

Perfectly cut diamond with a nice faceup size

Brian Gavin is well known in the industry for his high quality diamonds that are cut to extreme precision and vetted by the man himself. When we talk about round diamonds, most people are actually familiar with the phenomenon of hearts and arrows that are displayed when the stone is seen with a special viewer.

What most people do not know is that different diamonds might display different hearts patterning even though they are all graded as triple excellent GIA or triple 0 AGS.

By making a comparison between the Brian Gavin Signature against the above stones, you can actually see that Brian Gavin’s craftsmanship and facet precision is actually way better than most triple 0s.

Now, let’s take a look at the diamond’s specifications with details extracted from the AGS report.

Shape: Round Brilliant Table %: 55.7
Grading Report: AGS Depth %: 61.7
Carat: 1.511 Crown %: 15.3
Color: E Crown Angle: 34.9
Clarity: VS2 Star %: 57.0
Measurements: 7.36 x 7.39 x 4.55 Pavilion Angle: 40.9
Lab Cut Grade: Ideal Pavilion %: 43.1
Light Performance: Ideal Culet: Pointed
Polish: Ideal Fluorescence: Negligible
Symmetry: Ideal Girdle: Thin to Medium Faceted

With an E color, this stone has one of the best colors on the grading scale. For a large 1.511 carats diamond, it will face up completely icy white. One of the other things I love about this stone is the VS2 clarity grade it has.

It allows you to have a completely eyeclean stone without having to pay a larger premium for higher clarity grades like VVS or IF. In fact, this stone sits nicely at a price point of $23,397 which offers great value for money.

Optical Performance And Cut Precision Data

data to determine diamond's performance

From the technical data of the red saturated Idealscope and ASET images, it indicates immense light return and a diamond that is ready to burst into fireworks under different lighting. This is really as good as it gets when it comes to a diamond’s optics. Refer to these reference charts to do your own comparisons.

In the next column of information below, you can see the relationships between the individual facets from the Sarin report. Basically, a Sarin scan uses light to precisely map the positioning and alignment of the different facets. A smaller deviation in the numbers means that the diamond is cut to stricter tolerances.

For example, the measurement of 8 different crown angles across the diamond yields values between 34.7 – 34.9 degrees. That’s only a 0.2 degrees difference across the entire diamond! Likewise, the measurements of the pavilion angles and diameter also show super strict tolerances in which this diamond is crafted to.

Diamonds of such quality don’t come by often and they get snapped up really quickly. If you are looking for a nice sized diamond with optimum light performance, this is a stone I will highly recommend you to consider.
