NEVER - E V E R!
I had a $10,000 diamond and platinum ring made that was not at all styled as requested even though pictures were provided, had to be remade which cost ME more money, was MONTHS late on finishing due to delay after delay, came in priced at a higher than quoted cost, and lasted ONE year before literally falling apart from shoddy workmanship. And then the owner lost my diamond when he was examining the damage. Need I say more?
