What deserves a closer look
- Screening only: bow-tie, windowing and contrast in a cushion can only be judged from images or video of this exact stone.
What to check on the exact stone
- Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
- Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
- Can you show me the inscribed report number under a loupe before it is set?
