Seth Godin wrote Meatball Sundae, a book about mixing old and new to get something pretty unappetising.
The key word here is "online". What people online hate is discovering that they've "downloaded a sales call" (just as they hate having a salesperson come up to them while browsing in the store).
So forget the fact that you are paying all those salespeople's salaries. Think instead about how your customers really want to progress their interest.
80% of your online customers want to complete their purchase online. But your site is letting them down.
Perhaps they want to see the jewellery on them - there are apps to do exactly that taking a selfie and superimposing. Or they want to see models, celebrities etc. sporting the same items. Or they want practical help - a sizing guide, a what size looks best for you tool, a colour matcher, wrap it for you or simply delivery costs. Or they want reassurance - a no quibble return option, guaranteed trade-in, or a send it to a friend system for gifts which also offer a swap for an alternative option.
For the remainder, there are a host of options.
A click to chat, which instantly connects them with a salesperson. A home or hotel visit from a personal shopper. A guaranteed store appointment, where they get a special fitting (this can be sold as a premium service). Even a credit advisor who can help them finance their purchase.
There is one sure way to make sure customers fall through the cracks. Not following up while the idea is in their minds, but instead allocating their enquiry to a salesperson who follows up when it suits him/her and often phones when the prospect is with the person they are buying for, busy or offline. By then the prospect will either have bought, seen something else online which interests them more or gone off the idea. And telephone messages from a jewellery store on a partner's phone can look highly suspicious.
Think of your customer and how they like to buy, not your need to keep salespeople fed with work.
