About a jewelry online simulation tool - website?

[Jake]

Simulation seems like a poor term for the site, which is a good idea.

Interactive design tool, or design preview seems like a typical names for such a thing.

Applying some SEO may be appropriate, a quick check of OpenSiteExplorer.org report their tool has found no links to your site, a key factor in getting search ranking.

Putting images of designs on various free social, gallery sites might help, Pinterest has a strong female demographic. Create a free business Facebook page, you can log in under the business name so any comments on pages or in groups links to the business page. Paid Facebook ads cost a bit less when they go to a Facebook page, rather than off site, some run sweepstakes that require giving a like to qualify, contests like that get high ad click rates which reduces the cost of clicks, perhaps to less than 10 cents each.
Perhaps have a design content where people's ideas are put in a gallery, the winner gets their design as a prize.
