What's the best place to buy a 18k gold necklace?

Ticagro: jewlers Bench has the best

Costco. And yes, 18ft is softer than 14kt and will likely scratch easier. I would search the internet for options other than buying locally. I know that sounds ugly, but you will pay a higher price locally for sure.

She specifically mentioned 18k. I have no idea why. She's tiny but fierce, so I better get her what she wants.

Ticagro :
I get my necklaces from Thomas Markle in the woodlands. Think hard about a thin 18 gold though. It is a very soft metal and would break easily. I buy 14 kt because it is so much stronger. But if she is set on 18 kt then you better stick to that.

ZMAN :
It was a VERY special gift for my wife at her request !

Ticagro : It's a deeper gold color, may match the piece she wants to put on it ....special request. She has excellent taste.

luv2eatsushi : She certainly does, look who she married!

Ticagro : Sooooo Jewelers Bench, Dixon, Thomas Markle. All good choices and you will have a beautiful piece.

Do your research then go to a Pawn Shop....

ZMAN :
True. However, those other jewelry shops are going to wrap it and soooooo when she opens it.. bada boom! The presentation is the icing on the cake.

Pawn shop?
