Who is RenéSim?

Online Jewellery Store

RenéSim is Europe's first luxury jeweller to offer its premium jewellery creations online only. As an exclusively online jeweller, RenéSim combines 180 years of traditional family craftsmanship with all the benefits of modern online shopping.

RenéSim offers you the revolutionary opportunity to customise the designer jewellery you select according to your personal taste. In just a few simple steps, the intuitive guided process enables you to choose your personal combination of fine gems and precious metals (including platinum, rose gold, white gold, yellow gold and palladium). Your premium designer jewellery, designed by Franz & Maximilian Hemmerle, thus receives the additional status of a uniquely personal creation. Select your own preference from thousands of options, and it will be made exclusively for you.

All our jewellery is created and produced in Germany, using supreme-quality materials and only real gemstones of high quality. By taking advantage of the Internet we have done away with stores and salesrooms altogether. Thus we can offer you a revolutionary shopping experience at outstanding value for your money.

Homage to René Sim Lacaze.

René Sim Lacaze was a French jewellery designer who was commissioned by the most preeminent jewellery houses to create stunning pieces of jewellery. He is the inspiration behind RenéSim.

How do I choose my piece of jewellery?

The RenéSim Collection comprises an array of jewellery lines to inspire and delight you. Simply click on the 'Collection' button in the main navigation bar. To browse our range of rings, for example, select 'Rings' in the main navigation bar to display the full range of rings available from RenéSim.

You can also use the search function. Enter the name of your desired item to display all relevant results automatically. Popular search terms include a type of jewellery (e.g. ring), specific gemstone (e.g. tourmaline), material (e.g. rose gold) or gem colour (e.g. green). 

How do I customize my piece of jewellery?

RenéSim offers you the opportunity to customise designer jewellery according to your personal tastes. Select your preferred precious metal and choose from up to 15 different gem types. These choices give you thousands of possible combinations – all of them resulting in a unique piece that's yours and yours alone.

A few simple steps to your personal unique piece of jewellery:

First select your desired piece of jewellery. RenéSim offers every design in a prêt-à-porter version. Select this, then click the 'Customise' button directly next to the product image. In a few simple steps, you can design your personal customised piece of jewellery in exactly the colours you want. For the fastest way to your personal piece of jewellery, click here.

Can I have my jewellery engraved too?

It's simple to order engraving for all items which can be engraved. To order engraving for customised and prêt-à-porter pieces, click the 'Customise' button. A choice of three fonts is available. If the displayed options do not meet your wishes, please contact us by telephone or e-mail!

Does RenéSim also produce completely unique pieces?

At RenéSim, we are primarily jewellers and jewellery designers. We are naturally happy to apply the full breadth of our imagination in creating unique personal designs from decades of personal experience and 180 years of family tradition.
