Buying estate jewelry is a skilled profession and not for the weak of heart or spirit. It's a daunting task for the first-timer.
You may have decided that it's not for you.
But if you are now champing at the bit .. STOP!
Start Over!
What!?!
Take all the information you can get, filter it with common sense and use it wisely.
Don't start until you are ready.
But if you do prepare yourself properly, don't be surprised if you find a sparkler that you bought "way below wholesale!"
Of course neither the neighborhood bitch ... nor your sister-in-law ... needs to know that.
