Etsy shop not responding

I finally found a piece of jewelry that I absolutely adore (I’ve been looking Everywhere!). I messaged the Etsy shop a week ago asking about a special request/custom order (I want it in gold, not silver). But I haven’t gotten a response. I have since messaged them again explaining how excited I am about this necklace, but still no response. I have checked my Etsy account and my email - but nothing.

What options do I have here? I don’t really want to contact Etsy itself because then why would they want to make a necklace for me after tattling on them? But I REALLY want this piece. What do I do? Suggestions?
