THe rule of thumb is two month’s salary that the gentlman makes. Let’s forget that bullshit, shall we? You can do better than that.
I found a 3 carat ring worth $28,000 and got it for $8,000. I did that by scouring the ads in the largest newspaper in my area (in this case, The Atlanta-Journal Constitution). It was before Craig’s List became so well-liked, but I recommend shopping on Craig’s List, too.
Do NOT go to a mall jewelry store. Do NOT got to a stand-alone jewelry store. Do NOT buy from a dealer online. Diamond mark-ups are 10% – 20% higher online. Instead, buy a distressed diamond from a private individual. Make sure the documentation has a picture of the diamond you are looking at so that you can make sure the documentation isn’t for some other, better diamond.
Prongs can hide a world of problems, from feathering to coal specs. As long as the prong hides it, that may be all that matters to you, and that is perfectly fine. But beware of fractures!!! These are usually only seen in “I-1, 1–2, and 1–3 diamonds. But you really do need to look for yourself.
Take a jeweler’s loupe with you. they are very cheap, but can save you thousands.
You’re right about the 4 C’s, though. Learn what you need to know so that you can make an educated decision. Please do not make an impulse buy just because it’s “pretty” and “has a lot of fire”. ALL diamonds have a lot of fire under spectrum lighting. That’s why jewelry stores use them. A lump of coal would sparkle under thier lights.
I am a die-hard pragmatist, which is why I bought a large stone. I knew that if I ever ran into finanial trouble I could sell that sucker and help my family. Depending on your relationship with this woman, it may be something the two of you want to discuss. The larger the stone, the more fun it is to wear it!! But it is nearly impossible to get your money back on a small stone. Make SURE you buy at least half off full retail value, if not two-thirds. You may need that money back one day.
Congratulations!!
