Best options in One Carat Diamonds for $7000 from Ritani

By Todd Gray

January 2, 2014

Hi Todd, I am looking to purchase an engagement ring from Ritani (I like the idea of being able to preview it before purchase) and was hoping you could help me select a couple of diamond options. I am looking for something Ideal cut, approx. 1 ct, D-H & FL-SI1, and around $7000. Thank you in advance for your help! — Blake J.

Round Brilliant One Carat Diamonds from Ritani:

Ritani ideal cut diamond, GIA 2151683249Thank you for your inquiry Blake, I took a look at the current diamond inventory of Ritani and found two options which look spectacular! The first is this 1.06 carat, H-color, SI-1 clarity, Ritani ideal cut diamond which is graded by the GIA with an overall cut grade of Excellent. According to the GIA, the diamond has a total depth of 60.8% with a table diameter of 59% with a crown angle of 34.5 degrees which is offset by a pavilion angle of 40.6 degrees with a medium, faceted girdle and no culet.

Now the 59% table is a little beyond my normal selection criteria, however this diamond is still technically within the parameters for the zero ideal cut proportions rating as designated by the AGS Laboratory, and the crown and pavilion angle measurements are spot-on and will produce great light return with a virtual balance of brilliance and dispersion (fire) with great scintillation.

The primary inclusions are indicated as being crystal, clouds, and needles, which are all various forms of diamond crystals that were trapped within the larger diamond crystal as it formed. There is also a couple of tiny feathers which appear to be of no consequence.

Ritani 1 ct., Diamond Review ~ GIA 1169271724:

Round Brilliant Ideal Cut Diamond from Ritani, GIA 1169271724The proportions of this 1.12 carat, H-color, SI-1 clarity, Ritani ideal cut diamond are a little tighter than the 1.06 carat described above because the table diameter is 56% with a total depth of 61.8% and a crown angle of 34.5 degrees offset by a pavilion angle of 40.8 degrees with a medium, faceted girdle and no culet. This set of proportions is well within my preferred range which I outline in my article 15 Seconds to Diamond Buying Success, but keep in mind that there are other combinations which produce similar results which is why the 1.06 carat from above is still worthy of consideration. The primary inclusions consist of diamond crystals and a feather which is larger than those contained within the 1.06 carat, but which is well within the body of the diamond and thus it does not concern me in the least.

Now I realize that you specified that you are looking for one-carat diamonds, but you also indicated that you were interested in diamonds of higher color and clarity. In order to get into a diamond of higher clarity and color within your desired price range of $7K the carat weight of the diamond would have to drop down into the range of 0.90 – 0.99 carats, however I could not find a single option which meets my selection criteria within the current inventory of Ritani diamonds.

Crafted by Infinity Hearts and Arrows Diamond:

Crafted by Infinity Round Brilliant Cut Diamond, AGSL 104062444005I found this spectacular option within the inventory of High Performance Diamonds, it’s a 0.967 carat, H-color, SI-1 clarity, Crafted by Infinity Hearts and Arrows Diamond graded by the AGS Laboratory with an overall cut grade of AGS Ideal-0. Now I know that one of the things that you like about Ritani is that you can have the diamond shipped to a local jeweler who is an authorized representative of Ritani and be able to see it before you buy… well Wink at High Performance Diamonds has a program called “See it to believe it” which takes the risk out of buying a diamond online… and frankly, I like this option better than the options from Ritani because I’m able to judge the optical symmetry of the diamond because Wink provides all of the reflector images required for me to do so on the diamond details page.

Plus this diamond is graded by the AGS Laboratory on their Proprietary Light Performance grading platform which goes beyond the grading criteria of the GIA Laboratory by using Angular Spectrum Evaluation Technology (ASET) to determine the brightness of the diamond and provide insight into where the diamond is gathering light from within the room. This information is represented on the Diamond Quality Document by the multi-colored images of the diamond that appear in the center of the report, red represents the brightest amount of light and green represents the second brightest light.

I can tell by the ASET image for this diamond that the diamond is going to be bright and lively, it exhibits a lot of red and the green areas are evenly spaced and consistent throughout the diamond. The center region of the table facet is green in color, but this is normal because the colors red and green are common for this area since light enters the diamond from 45 degrees and both colors share this angle of coverage.

Brian Gavin Signature Hearts & Arrows Diamond:

Brian Gavin Signature Hearts and Arrows round brilliant ideal cut diamond, AGSL 104064191008Another option which I really like is this 0.946 carat, G-color, VS-2 clarity, Brian Gavin Signature diamond which exhibits a crisp and complete pattern of hearts and arrows. This diamond is also graded by the AGSL with an overall cut grade of AGS Ideal-0 and the ASET image looks spectacular. The inclusions are just a couple of diamond crystals, needle shaped diamond crystals and small feathers… you can see a few of the diamond crystals reflecting within the hearts pattern, this is because the scope which is used to grade hearts and arrows for consistency of facet shape and alignment is backlit and contains a magnifying lens.

While Brian Gavin does not offer a way for you to see the diamond before you buy it, they do have an excellent inspection and return policy, and the diamond details page features a high-resolution video of the diamond which provides great insight into the volume of light return and sparkle.
