There is a lot of information and misinformation about whether or not yellow gold makes a white diamond look yellow. I'm going to use photographic evidence to come up with some answers.
Here are four photos of my 0.51 G VS1 hearts and arrows, Triple Ex diamond ring set in 18k yellow gold. In these photos I have put the ring next to a silver and cubic zirconium art deco earring so that the two pieces of jewellery can be compared. The silver is a white metal and the cz gems are D colour. I have tried to slant the earring away from my ring so that the majority of the cz gems will not be influenced by the gold colour of my ring. The ring and earring are subjected in each photo to exactly the same lighting conditions.
If the yellow band and yellow prongs alter diamond colour you should see a noticeable difference in colour between the diamond and the cz gems. If the band and prongs don't alter diamond colour then you won't see any difference in colour between the diamond and the cz gems.
Please now look at the photos and make your own decisions about what you think. Do this before you read the rest of the text so that you are not influenced by what I think.
Photos 1 and 2 are taken outside on a cloudy Scottish September day at a lattitude of 56.18 degrees North, away from any brightly coloured objects. The photos are taken with a Samsung Galaxy S4 on the Auto setting. The colour has not been enhanced or altered in any way. The white paper has been placed underneath in an effort to standardise the background. I see no difference in colour between the diamond and the cubic zirconia.
Photos 3 and 4 are taken indoors under natural daylight with the same camera and the same settings. The room walls are cream.
Photo 3: This has not been enhanced or altered in any way. I see no difference in colour between the diamond and the cubic zirconia.
Photo 4: This is simply photo 3 with the colour saturation increased to +75 (using PhotoShop Elements). The increased colour saturation will emphasise any yellow that might have been reflected in the diamond. It will also show whether increasing the colour contrast between prongs and the diamond makes the diamond look whiter or yellower.
If I look closely at photo 4 (increased colour saturation) I can see there is a very small reflection of the yellow prongs on the diamond itself. This reflection is very close to the prongs and I estimate that it does not extend more than 0.1mm away from the prongs. This is quite close to the limits of visual accuity. Maybe a very young person with 20/20 vision viewing a diamond in bright light from a distance of about 10cm might notice this slight reflection but the rest of us wouldn't notice it at all. I also think that when the colour contrast is increased the white diamond looks whiter.
Some thoughts
1. I think that yellow gold settings and yellow gold prongs make a very white diamond look......very white.
2. There may be other reasons for using white gold or platinum settings/prongs (including personal preference) but enhancing the whiteness of a diamond isn't one of them.
Mythbusting continued
For my next post I will discuss whether or not we should use the diameter of a diamond to work out its apparent size...
