Our take on the 1.01 ct. K/I1 Round Diamond

A 1.01 carat round brilliant loose diamond graded K color and I1 clarity, with very good cut, polish and symmetry and no fluorescence. At this grade the stone is a budget route to a one-carat round, but I1 clarity means visible inclusions are likely and K color will read warm in white metal. The best new price is $1,270 at Mikado Diamonds as of November 5, 2026, and it is the only new listing tracked, so there is no recent price range to compare against.

Pros
  • Just over one carat, so it faces up as a full one-carat round
  • No fluorescence, so no oily or milky look in daylight
  • Very good cut, polish and symmetry grades
  • 57% table and 62% depth are within a balanced range
  • $1,270 is low for a one-carat round
Cons
  • I1 clarity usually means eye-visible inclusions
  • K color looks tinted next to white diamonds and in platinum or white gold
  • Very small culet and medium-to-thick girdle add nothing to the face-up size
  • Only one new listing, so there is no price competition
  • Resale value at these grades is weak

Questions and answers

Is a K color, I1 clarity diamond a good buy?
It is a value buy, not a quality buy. You get one carat for $1,270, but expect visible warmth and likely visible inclusions. Buy it only if you have seen the stone or a clear video.
Will the inclusions be visible to the eye?
Often yes at I1. Many I1 stones have marks you can spot without a loupe, especially from the side. Ask for a magnified video and check the plot on the IGI report.
Does K color look yellow?
It has a noticeable warm tint, more obvious in white gold or platinum. In yellow or rose gold it blends in and looks closer to near-colorless.
Is this stone worth it against a lab-grown diamond?
A lab-grown diamond of similar size in better color and clarity often costs less than $1,270. Choose this natural stone only if you specifically want a mined diamond.
What comes with the diamond?
The listing describes a loose stone with an IGI lab report. Confirm with the seller whether the report is included and whether the stone is natural or lab-grown before buying.
When is the best time to buy?
There is only one new price tracked, $1,270 at Mikado Diamonds as of November 5, 2026, so there is no sale pattern to wait for. Compare against other listings for the same report number.
Where is the 1.01 ct. K/I1 Round Diamond cheapest?
At Mikado Diamonds, for $1,270.00, as of our latest check.
