“My girlfriend and I are considering several different Brilliant Earth engagement rings. The frontrunner is the Willow wedding set. We’ve visited several jewelry stores in our local area. We both agree that a diamond in the range of 0.75 – 0.80 carats looks best on her small fingers. We have a budget of about $5,000.00 to spend on the diamond. Could you help us find a diamond from Brilliant Earth that meets your selection criteria? We’re having difficulty finding suitable options based upon that selection criteria. But you mentioned that there were other combinations of crown and pavilion angle that might work. We’d like to stay in the F-G color range. Eye clean SI-1 clarity is acceptable, but we really don’t want to be able to see any inclusions with just our eyes. We’d like the best cut quality possible, so GIA Excellent or AGS Ideal is preferred. You can respond via blog post if you’d like. We’re still in the research phase of the decision making process. Just want some professional guidance. Thank you.”
The first thing you’re going to want to do when looking for diamonds to set in Brilliant Earth engagement rings is set the advanced options:
The next step will be to right click on the word “VIEW” which appears to the right of each diamond listing. Right click your mouse over the word “VIEW” and click the option to Open Link in New Tab. This will open up the diamond details in a new tab in your browser window. The next step is to find the GIA icon and click on it to open up the diamond grading report. This will enable you to determine the crown and pavilion angle offset.
To maximize the volume of light return, I prefer that the pavilion angle be between 40.6 – 40.9 degrees. A crown angle between 34.3 – 34.9 tends to prefer a virtual balance of brilliance and dispersion. Note that the GIA will round a crown angle of 34.9 degrees up to 35.0 degrees, so you will need to consider diamonds with that crown angle.
One of the eight options that resulted from my search of diamonds for Brilliant Earth engagement rings met my selection criteria by the numbers:
This 0.80 carat, F-color, SI-1 clarity, GIA Excellent cut round diamond from Brilliant Earth has an overall cut grade of GIA Excellent. The 40.8 degree pavilion angle should produce a high volume of light return. While the 35.0 degree crown angle provides a virtual balance of brilliance (white sparkle) and dispersion (colored sparkle). The 80% lower girdle facet length is likely to produce pin-fire type sparkle that is smaller in size. Think disco ball. If you prefer broad spectrum sparkle like me, then you’ll want to look for options with a lower girdle facet length between 75 – 78%. Broad spectrum sparkle tends to be larger in size, bolder, and more vivid.
Unfortunately a clarity photograph was not provided for this diamond. So we have no way of knowing the extent of the inclusions. Nor were reflector scope images provided. I can’t tell you anything about the degree of optical precision exhibited by this diamond without an ASET Scope, Ideal Scope, and Hearts & Arrows scope image. I’d like to see Brilliant Earth step up their game and provide clarity and reflector scope images for all of the diamonds that they offer. As you will see momentarily, the offer clarity and reflector scope images for some of the diamonds in their inventory. Why not all of them?
The primary inclusions within this diamond are indicated as being feathers and twinning wisps. A feather is a minute fracture within the crystal structure of the diamond. A twinning wisp is a twisted crystal plane which contains included diamond crystals. These are the type of inclusions that make me hesitant to recommend a diamond without detailed clarity photographs. I want to see the extent and location of the feathers. I want to be able to determine whether the diamond crystals contained within the twinning wisps are light or dark in color. Perhaps Brilliant Earth can provide images upon request. Be sure to ask if this diamond is of interest. Please forward the images to me for further review.
This 0.80 carat, G-color, VS-2 clarity, GIA Excellent cut round diamond from Brilliant Earth got my hopes up. I saw the clarity photograph and reflector scope images provided on the diamond details page. I thought that I’d struck gold because they have this diamond listed in their Super Ideal category. Unfortunately the diamond has a pavilion depth of 43.5% which happens to be the critical tipping point where light begins not to strike fully off of the pavilion facets. The pavilion is the lower half of the diamond which is designed to direct light back up towards the observer. My suspicion was confirmed when I clicked on the icons for the Ideal Scope and ASET Scope images. The diamond is leaking light underneath the table facet. So even though the pavilion angle of 41.0 degrees is only one tenth of a degree beyond my preferred range of 40.6 – 40.9 degrees, this is not a diamond that I would recommend. But it provides a great example of why clarity and reflector scope images are critical to the consideration process. Without reflector scope images, you might incorrectly assume that the proportions of this diamond are close enough. The article “What do the different colors of ASET mean?” provides more insight.
