You Guys can't even imagine how i'am happy it is worth more than anything, btw lip mark is comming from the metal collar, when collar is custom made for each crystal, (first You need to do very complicated drawing and check dimmensions) there be no lip mark, or even if it is so small that its really hard to seen by naked eye, and durabilyty is amazing too as lab. was useing saphire to increase durabilyty, we made tests and it was extremly hard to scratch it from the crystal, so we used diamond powder and proffesional dremel for cleaning and then it came off but still it wasnt that simple
