The purpose of the 4cDiamond app is twofold – to provide you with information on tradeoffs for choosing different values of the 4Cs, and to estimate the value of the resulting diamond. The overwhelming majority of the price of a diamond ring is the cost of the diamond itself (the metal ring and setting add little to the total price), and in our experience proper knowledge of tradeoffs and value can save customers substantial amounts on the price of a diamond they would have otherwise purchased at unnecessarily high C levels, or be able to purchase a larger carat diamond with imperceptible-to-the-naked-eye differences in the other three Cs (cut, color and clarity).

As with any estimation, there will always be some error in the estimate, but we try to keep this to the minimum.

Also, as with estimating the value of an extra bathroom or bedroom in a house in a particular neighborhood, estimates are only as good as available sales data in that neighborhood, or available diamond price data. We use frequently updated online diamond prices for our estimates. You should expect to pay more than our estimated price if you purchase the same diamond from a physical store, and the difference will depend on how much of rent and other expenses the store is paying.

Currently our app is only for round diamonds, the most common diamonds sold by far; and only uses online price data in the United States.

Wonderful, useful app

This app does a great job of telling you the trade offs in choosing different values for the 4 C's. Many sites can give you price information, but you need to know the C's you want to buy. Most people don't know how much extra they need to spend to go one level up, or save by going one level down. This app helps you with that and can save you quite a bit of money, several hundreds of dollars. Well designed, easy and intuitive to use.

Awesome app

This is an amazing app. Easy to use and figure out the size and quality of diamond I would get within our budget. Spent hours trying out different combinations to find a nice diamond for myself for Valentine's Day, so that my husband would have an easy time buying the perfect diamond, based on my C-choices.

Love it

This is an excellent app. to learn more about diamonds and price fluctuations based on going one level up or down in any one of the C's. It is fun to play around with to design your ideal diamond based on your budget. The best part is the ease of navigation which makes it more valuable than anything else out there. 5 stars!
