My wife of 23 years is about to graduate with her nursing degree. She dropped out of school 21.5 years ago to stay home with our kids and take care of things at home. She very successfully homeschooled 3 kids, did an incredible job taking care of things at home, and is an unbelievable cook! She’s had her eye on the Tiffany Diamonds by the Yard necklace and I would like to buy a similar custom made piece as a small thank you for all her sacrifice, to let her know how lucky I think I am, and to celebrate her new achievement. I am however, unfortunately, lost on jewelry buying including understanding what I should be buying for her (she has very exacting standards) but is also very price/value conscious. She graduates in about 12 weeks. I know she wants a thin bezel and about a 1/2 carat diamond. Help! Where do I start?!?!
