I had a 1 ct equivalent moissanite from the company "transgems" that I used to wear as my ering before I upgraded. It was set in sterling silver with rhodium plating. It was sold as a JK color and I think that was accurate.
It's a beautiful stone but I feel weird wearing a solitaire white stone as a RHR.
I baked it at 425 for 1 hour and it turned slightly champagne in color. I'm so thrilled. The change is very subtle but I asked my husband with no prompting what color the stone was and he said "light brown or yellow" so I know I'm not imagining it.
I'm going to bake it more and post some pics.
Hopefully the color doesn't fade over time but for now, I recommend it if you want to add warmth
