It's the same VDI for all White's. 14k and 18k bracelets and necklaces will come up as VDI 0, 1, 2, 3, 4, around in that area. Chunkier gold rings will come up as higher VDI, 20s, 30s, 40s.
The VDI are the same as my M6 and VX3. I made a video with some VDI numbers on it. Advance to 2:30 and you'll see what a 14k figaro rings up as:
Hope this helps.
