That’s the sisk gemology reference…it’s a 3 volume set, but unfortunately only the third volume is still available. We’re working on a new printing and will definitely announce it once that happens.

the same way you judge anythings market demand. look at supply size and availability. look at the price. fair market value is always a good indicator as things get scarce the value goes up fast. there is a huge supply and prices go way low. the other major factors are how available it is to get. a gem you can only mine in 1 place and only for a few months is going to always be high demand just due to rarity and exclusivity. its hard to get and its also far away to anyone that doesnt live there. the farther you get from the source the rarer things get and the price climbs as distance grows. but if you can mine for it anywhere its never gonna be rare or scarce so its stuck at low demand. the market changes every year too due to new discoveries new fads or phases and such but good colors always sell good clarity always sells but now inclusions are hot iridescence is smokin and stones that react to things are a selling point. the more things this inanimate object can do without broadcasting that can also drive whole other values to collectors. including freak accident specimens that do things they are known not to do. those are the ones that set the price curve and the others fall in line. many stones ive purchased from a collector or gem store. i show them things they never even knew about it and they always regret what it was sold to me for cause i got a winner. most of my finds are pretty good when im out looking too because i have an eye for these things and it really helps. being able to tour a gem store owner through his own shop and show him new things about all of his gems and teach him things he never even imagined isnt being rude. knowing what your selling is key and so is knowing what you have. also knowing if you can trust the appraiser is infinitely valuable and multiple opinions really matter. i have identified a few pieces of jewellery that many thought were worth nothing like less than 100 bux if you melted the chain too. and turns out they were in the 10's of thousands of dollars. like 2-3 were worth 50+ grand. and they argued with me when i told them they might wanna get those checked out cause the times have changed. and ohh boy they did. turns out their family was livin large and they didnt even know.

In Jewelry terminology, each carat is subdivided into 100 points, so for instance a “25 point gem” is .25 ct.

She's like 12 or something

She’s not 12. She has a master’s degree. And she’s married.
