Hello, this is a wireless comparison of QRU, QRD, QRT rose quartz in 6 and 8 mm. The different letters QRU, QRD, QRT, QRQ correspond to storage boxes for me so that I can distinguish what you are ordering. The visuals here will allow you to see the beads without wires. Thread can alter your perception of color by reinforcing it. This will allow you to get a more real idea of color. The visuals were made outside and inside.
