Diamonds value?

I was wondering if anybody knew the values of the following colored diamonds
Black Diamonds
Pink Diamonds
Red Diamonds
Blue Diamonds
Yellow Diamonds
Green Diamonds
White Diamonds

Because I was hoping to put the black diamonds on an engagement ring surrounding a big pink diamond for my girlfriend (seeing as how those are her fav colors)and I was wondering how much it would be worth if say it was 15 carats or higher?
It would really help me out so please tell me and I'm also wondering if there was anyway to make these diamonds like more valueable than diamonds that are usually put on engagement rings?

16-years-old and already getting engaged? Wow.
I think you should wait till you are older to look into it.

Yea I know but I mean for the future because I want to be prepared and have the perfect ring for my girl

If you go to the jewelers, they will be able to tell you all about it. I think that would be the best thing for you to do. Sometimes when you look up values of things on the internet, they are wrong, so I wouldn't 100% depend on it.

oh HELL no, lol 15 carat COLORED diamonds?!? that's insanity... that'll cost you in the millions, no lie. colored diamonds are much more rare and SO MUCH more expensive than normal ones. especially the pink diamond.

Blacks diamonds aren't big in the industry because they're harder than regular diamonds so they'll be harder to come by and a little more expensive. Pink diamonds are the most expensive diamonds for the simple fact that they are pink and all women want some pink diamonds. Unless you have around 12k+ to spend on an engagement ring you might want to re-think your plan of action.

I'm getting around 2-3 carat total white diamond which will cost around 3k for the clarity, cut, and color I want. Then add on the frame and the placing of hte diamond and everything comes around 5-7k on a great engagement ring. Please look into diamonds before you throw cash away and stop dreaming about a crazy diamond ring that you probably can't afford.

No worries guys I can afford it and thanx for the info
I really appreciate it = )
And bastrdassinjun don't worry dude I'll take your advice and look into these things carefully
Hey is it also true that black diamonds are from space?
Seeing as how they have interstellar qualities?

O.O wow, do those even exist...

well major reccomdation for you as cool as colored diammonds are they do not look good combined on a ring she's supposed to wear every day and yet have it still look good, every girl dreams of a classy ring go platnium and use one consecutive color if you want to mix the pink in there's is this form of white gold that lets off a pinkish tint.

well whatever you choose hope she likes it
