What earned a seller a column
Independent certificates on center stones, HD imagery or video of the exact stone, a real 30-day-style return window, and sane resize policies. All four clear that bar; the table is about emphasis, not survival. Whichever you pick, verify the certificate number on the grading lab’s own site before the return window closes.
The disclosure, plainly
The buttons above are affiliate links: if you buy through one, we may earn a commission at no extra cost to you. That funds the site and does not reorder the columns. Policies drift, so confirm the current return and resize terms with the seller before paying.
