I'm thinking of using one of these gems for an engagement ring..but i dont want something that isn't "special"

I would like to purchase GREEN AMETHYST, MORGANITE, & KUNZITE. With the exception of green amethyst, I've never seen any of these gems used in the tangible marketplace--I mean, I've never seen a kunzite pendant at Macy*s or a morganite ring at Ben Bridge. I've only heard of and seen morganite & kunzite on GemsTV. I'm wondering where I can buy these as loose stones, OR as already made jewelry pieces? Any information would be greatly appreciated :)

I have a beautiful cushion cut Kunzite, very nice pink in color that has not been heat treated and it's huge, way too big for a ring. I took it to some various jewellers to make sure it was Kunzite and one of them told me it was worth about $700. I would like to sell it but not sure what is the best way to do it. I've looked on Ebay and the prices that are being bid are very low. I've looked at Gemstone dealers and their prices are much higher for cut Kunzite but all seem to be selling, not buying. I've never done this before and wondered if anyone had any websites for dealers that will consider buying gemstones or just any advice on what is the best way to sell it. I'm going to take it in again and have it weighed, clarity etc done so I can list it correctly but just don't know how to start selling it apart from putting it on Ebay. Thanks
