“Hi, I wanted to find a round cut diamond around 1.1 to 1.3 ct, E/F color, VVS-1 to VS-1 clarity, ideal cut with H&A. Could you please help? and do you charge for the consultation?” — Xin L.
I’ll be happy to help you evaluate some options for round brilliant ideal cut diamonds weighing between 1.10 – 1.30 carats, E to F color, and VS-1 or higher in clarity, which are cut to a level of optical symmetry precise enough to exhibit a crisp and complete pattern of Hearts and Arrows, like this 1.175 carat, F-color, VS-1 clarity, Crafted by Infinity Diamond pictured to the left, which is currently available from High Performance Diamonds.
This diamond is a perfect example of what I look for in a diamond, it is cut to the middle “target range” of the spectrum designated for the zero ideal cut proportions rating by the American Gem Society Laboratory (AGSL) with an overall cut grade of AGS Ideal-0 on their Proprietary Light Performance grading platform, which uses Angular Spectrum Evaluation Technology (ASET) to determine how bright a diamond actually is, and provides insight into how evenly light disperses throughout the diamond.
The ASET image for the 1.175 carat, F-color, VS-1 clarity, Crafted by Infinity Diamond which is appears in the middle of the Diamond Quality Document (DQD) issued by the AGS Labortory, as provided on the diamond details page referenced above, indicates that the diamond is exceptionally bright and that the light is evenly dispersed throughout the diamond. Be sure to read my article “What do the Different Colors of an ASET mean” for a full explanation of how to interpret the colors of an ASET image.
The primary inclusions are indicated as being groups of pinpoint size diamond crystals known as clouds, and diamond crystals, which are simply tiny diamonds that were trapped within a larger diamond crystal as it formed. These are my favorite type of inclusions since they are just diamond within the diamond, and as such pose no durability risk whatsoever. The girdle edge of the diamond is inscribed with the number from the corresponding AGS DQD and the Crafted by Infinity brand logo.
This 1.10 carat, E-color, VVS-2 clarity, James Allen True Hearts diamond is another option which is cut to the center “sweet spot” of the spectrum designated for the zero ideal cut proportions rating. The diamond is graded by the GIA with an overall cut grade of GIA Excellent, which is often referred to as “GIA 3X” or a “GIA Triple Excellent Cut” diamond, the GIA does not use ASET because it is proprietary technology belonging to the AGS Laboratory. The primary inclusions consist of diamond crystals in the form of pinpoints and needle shaped crystals. The girdle edge of the diamond is inscribed with the diamond grading report number “GIA 2156288346”.[separator]
This 1.20 carat, E-color, VS-1 clarity, Crafted by Infinity Hearts & Arrows diamond is being offered by High Performance Diamonds, the proportions of the diamond are right in the middle of the range and what I consider to be the “sweet spot” that all diamond cutters should strive for when cutting round brilliant ideal cut diamonds to exhibit the maximum volume of light return. Click on the clarity photograph of the diamond that appears to the left to access the diamond details page and use the loupe tool to get a good look at the inclusions which consist of diamond crystals, pinpoint size diamond crystals and small feathers which are of no consequence; the ASET image looks phenomenal.[separator]
This 1.308 carat, F-color, VS-1 clarity, Brian Gavin Signature Hearts and Arrows round brilliant ideal cut diamond is the largest option which I’m currently aware of within the range of specifications that you provided. As you can see from the image provided to the left, Brian Gavin provides an extensive amount of information on their diamond details pages, including a high resolution video of the diamond, clarity and reflector scope images.[separator]
This type of detailed information makes it extremely easy for me to be able to judge the degree of optical symmetry and determine that this diamond is going to be extremely bright and sparkly! The primary inclusions consist of diamond crystals and clouds of pinpoint size diamond crystals, all of which appear to be minimal as is typical of a VS-1 clarity diamond.
There is no charge for my diamond concierge service, the cost of my time is covered by the companies which advertise on this site. Consulting with me regarding your diamond project is a mutually beneficial scenario because you benefit from the 25+ years of experience I have as a buyer of ideal cut diamonds, and from the extensive contacts that I have developed throughout my years in the diamond industry; and your project gives me something to write about, which provides fresh content for the web site, hopefully answers questions that other people might have, and ensures the continued interest of my corporate sponsors.
