Dupes For My Beloved Laura Mercier Rose Rendezvous Illuminator?

If I had known how beloved my Laura Mercier Rose Redezvous Illuminator would become so irreplaceable I would have picked up two, but hindsight is 20/20. Now I am left with a little dilemma: my sister won't stop stealing it! I need to find dupe that I can buy for her (ok ok and for me too) so that I can preserve this limited supply of highlighting goodness. 

For the past two months we have searched high and low for the Guerlain Cruel Gardenia Meteorites but after having a sales associate laugh outright in our faces, we gave up. We have found some treasures along the way in all different formulas (reviews to come) but nothing that replicates the rose gold luminosity of this product. 

So my fellow beauty addicts, I beseech you! HELP US! I need to find a dupe before I resort to putting a padlock on my highlighter drawer and installing motion detector lasers.
