First of all, your site looks quite wonderful and well-made. I think the biggest issue to tackle is consumer trust. Having aspects like reviews, customer photos on social media (that are less than perfect), as well as a trust pilot rating might help.
Here are a few more suggestions:
Call to action button. Add some call-to-action buttons under your products on your landing page, as well as on your product page.
Connect Social Media. If you already have a growing Instagram account, it would help to connect the feed to your main site, thus giving it more social proof. Research shows that 76% of customers buy products seen on social media posts.
Influencer Collab. Since you have visually appealing products, it would be good to connect with micro-influencers, send them some of your pieces, and ask them to create some content for your social media as well as your Shopify store.
Connecting online with offline. If you have a showroom / physical store, make sure to always be telling your customers about your online store, adding a quick card with your online store address provides your new customers a chance to purchase again without coming to your physical store.
Testimonials. Try to showcase at least 5 testimonials on your site. Whether it’s from friends and family, or your offline store customers. Having some social proof helps boost consumer confidence in your site.
Ask your customers! (Most effective for increasing conversion) When you have some converting customers, ask them how they found out about your shop. You can easily do so with a post-purchase survey app, and reward your customers with coupons/points to keep them coming back again. Once you find out your strongest marketing channel, focus more effort and money on that.
Hope this helps!
