Diamond Rings are a big Fraud

--they are over priced because the investors "claim" it to be scarce (while it is not)
--and they have symbolized it through advertisement to be the biggest sign of love and they should never be sold (a master plan to control its worldwide price)

--when it comes to your spouse , she only cares about how pretty it looks , its price doesn't matter coz she is not going to sell it anyway

--the naked eye can only appreciate the setting

--therefore, if you have a diamond-look-alike stone , you can invest more money in the setting, you can even have it specially designed for your spouse to fit her personality and your feelings for her

and you will still endup paying way less
than you would pay in a regular diamond ring
