You are staking your claim on a phantom so-called jeweler who probably has sour grapes because he was probably fired from Tiffany.

All jewelry hacks will say that their product is cheaper, but their products are almost always of inferior quality.

On another note, have we settled your "re-badged Chevy" issues, or do we need to go over that again? My "re-badged Chevy" has superior Cadillac styling and nuances that are worth the extra %5K to me. Hey, it's not the same as the Chevy Blazer, and it's my choice. The Blazer is probably an excellent vehicle too. 'Nuff said.
