The last weave; condition grading, explained 

Each and every rug undergoes rigorous quality inspection before being listed. All last weave rugs, exclusively, are sorted into the following conditions: 

Condition: Very Good

A last weave item graded as "Very Good" will be free of stains and will not have undergone any professional repairs. In rare instances, you may notice a small area of slightly lower pile in the rug.  Additionally, some subtle color variations or Abrash > may be present, though these are not considered defects.

Condition: Good

A last weave item graded as 'Good' may be subject to areas of low pile in smaller areas of the rug, giving it a more vintage, pre-loved appearance. You might also observe small color-run stains on select pieces (either on the rug, or the fringes). Certain rugs of 'Good' grading will have undergone professional repairs to give the rug a second life. 

Condition: Flawed Gem

A last weave item graded as a 'Flawed Gem' will generally be subject to the same imperfections observed in the 'Good' condition but as a combination. Ie, areas of low pile, and a professional repair; Or, a small stain on the fringes, with areas of lower pile. Some pieces may also have more observable 'ebbs and flows' in the dimensions (ie, not perfectly parallel or perpendicular)
