Oval bezel cups in 14k yellow and rose gold are not made by any supplies that I have found and we don't have the time or the tools to make bezel cups so we are limited by what is available.
They don't come in either 14k solid yellow or rose gold :( only 14k white gold, 14k gold filled, 14k pink gold filled and solid 14k white gold.
If you want a oval solid gold bezel cup your only option is a serrated cup like this. It will work for most applications except direct pour resin designs. If you are making cabochons then setting the cabochon or using stone or gemstone cabochons this style will work just fine.
Hope this helps :)
