Our take on the Loose Diamond Round Brilliant .59ct GIA G I1 Solitaire

This is a single loose round brilliant diamond of .59 carat, graded I1 clarity and G color, with a GIA report. At .59 carat it sits just under the half-carat-plus mark, so it reads as a small but real stone in a solitaire setting. I1 clarity means inclusions are visible under magnification and often to the eye, so the cut and setting matter more than usual. The best new price is $799.99 at Wilson Brothers Jewelry as of November 5, 2026, and only one store lists it new, so there is no competing new price to compare against.

Questions and answers

Is an I1 clarity diamond a bad choice?
Not automatically. I1 stones have inclusions visible under 10x magnification and sometimes to the naked eye. Ask for the GIA plot and a video, and favor a setting that hides the inclusion, such as a bezel or prong placement over it.
Is $799.99 a good price for a .59ct GIA diamond?
It is the only new price listed, at Wilson Brothers Jewelry as of November 5, 2026. Compare it with other GIA-certified .6ct I1 stones, which often sell for a few hundred dollars more or less depending on cut and fluorescence. With one seller, there is no lower new price to beat.
Should I buy .59ct or save for a full half carat or more?
A .59ct stone looks close to a .60ct and usually costs less per carat than stones at or above the half-carat mark. If size matters, a well-cut .70ct I1 stone will look noticeably larger for more money.
What should I check on the GIA report?
Look at the clarity plot to see where inclusions sit, the color and clarity grades, and any fluorescence note. Strong fluorescence can make a G-color stone look milky in some lighting.
What comes with a loose diamond purchase?
Typically the stone and its GIA report; a setting, mounting and appraisal are usually sold separately. Confirm with the seller whether the report is the original and whether a return period applies.
When is this diamond cheapest?
Loose diamonds rarely go on seasonal sale, and with one new listing the price is set by that store. Watch for price drops on the listing and compare against resale or estate stones, which often sell below new retail.
