There! I took help from various websites and my own memory. Hope these helped in some way!
If not these, then you can google up some yellow-gold jewels and use those as names. You can even look up the actual names for certain shades of yellow and gold, then use those as names. Or you can even look up words in different languages (e.g Miel in French which means 'honey') that fall in the yellow/gold category and use those.
Or even words like.... Ember, Sunshine, Sol, Solaris, Luxury, Amber, Caramel, Marigold, etc.
