Okay so I bought a lot of loose stones from an estate sale, there were some junk rubies, a really nice sapphire and some other gems in there but one really caught my eye. A tiny 0.29 ct yellow diamond. I know yellow, after brown and black is the cheapest color of fancy diamonds but does this have any value? Also, take a look at the picture whar do you think the clarity is(Im guessing I2)? I took it to a jeweler and the gemologist wasn't in but the assistant tested it and it is a real diamond and weighs 0.29 ct but do you guys think: 1. I should invest in a GIA report? 2. It's naturally yellow and not heated? 3. what the clarity is? Thanks!
