Our take on the Loose Diamond Round Brilliant 0.59ct GIA G I1

This is a single loose round brilliant diamond of 0.59 carat, graded I1 clarity and G color by GIA, sold with its grading report. At 0.59ct it sits just under the half-carat-plus mark, a size that reads as a small center stone or a pair of accent stones. I1 clarity means inclusions are visible under 10x 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, the only new listing tracked.

Pros
  • GIA report documents color, clarity and carat independently
  • Round brilliant is the most widely available and easy-to-set shape
  • 0.59ct keeps the price below most half-carat-plus stones
  • G color is near-colorless and faces up white in yellow or rose gold
  • Single-stone purchase lets you choose the exact setting
Cons
  • I1 clarity means visible inclusions in many stones; inspect the plot
  • No cut grade given here, so light performance is unknown
  • Loose stone needs a setting, adding cost and a jeweler's labor
  • Only one new price tracked, so there is little to compare against
  • Resale on an I1 stone is well below retail

Questions and answers

Is an I1 clarity diamond a bad buy?
Not automatically. I1 stones can look clean if the inclusions sit near the girdle or under a prong, but many show eye-visible marks. Ask for the GIA plot and a video before buying.
Is 0.59ct big enough for an engagement ring?
It reads as a modest center stone, roughly 5.3mm across in a round brilliant. On a size 6 finger that looks dainty; in a halo or bezel it appears larger.
What does the GIA report tell me?
It confirms the stone is natural, 0.59ct, G color and I1 clarity, and plots where the inclusions sit. It does not grade cut quality on this listing, so ask for proportions or an idealscope image.
How much will a setting add to the cost?
A basic solitaire setting runs roughly $200 to $600 plus labor, and custom work costs more. Budget for that on top of the $799.99 stone price at Wilson Brothers Jewelry as of November 5, 2026.
Is $799.99 a good price for this stone?
It is in line with loose I1 stones near 0.6ct, and only one new price is tracked, so there is no spread to compare. Compare against other GIA-certified 0.55 to 0.65ct I1 stones before committing.
Can I return a loose diamond?
Return policies vary by seller, so confirm the window and whether the GIA report must come back with the stone. Loose diamonds are often final sale or subject to restocking fees.
Where is the Loose Diamond Round Brilliant 0.59ct GIA G I1 cheapest?
At Wilson Brothers Jewelry, for $799.99, as of our latest check.
