lab grown marquise luvansh

I’ve been looking for my future wife engagement ring on luvansh. I’m running into the problem where she wants an elongated marquise 3.0-4.5ct (atleast 2.1-2.2 ratio) and luvansh does not have the advanced options to allow me to pick L/W ratio to sort through the endless of options… I’m kinda drowning and would take any help offered!
