I learnt there's "retail gold" which is the kind we buy when we think of jewellery - white gold, rose gold and yellow gold. And they come most frequently in 18k and 14k, but also in 10k and 9k.
I learnt there's also a thing called Investment Gold, which can be white, rose or yellow gold if it's 22k (aka 916 gold), or yellow gold if it's 24k (aka 999 gold). It's just gold that has trade-in value at the jeweller's, from what I understand.
I don't know how the other karats translate to percentages - I suppose one can always google that. But I do know that 22k = 916 gold = 91.6% gold, and 24k = 999 gold = 99.9% gold.
(Hey, look what I found while googling for pics after writing this post...)
I learnt that the higher the purity, the softer the gold. Which means anything that's holding a stone / diamond / gem etc. (ring, earrings, pendant) will probably NOT be 999 gold. It'll be too soft to hold up the stone.

I learnt that at my jeweller's I can trade in 916 and 999 gold (see Investment Gold above). But if I wanna sell off all other types of gold (and silver), including any pieces that have gemstones in them, I'll have to go to a pawnshop... and conveniently, my jewellery store has a sister company that is just that. They also have a retail arm that sells a more affordable line of jewellery in addition to the regular buying and selling of one's precious metals, stones, watches etc. And yes, they also deal in secured loans. Exactly like this -
I learnt that if a pearl is genuine (and not synthetic aka plastic) you will be able to rub another pearl against it without damaging it. You'll get some powder / fine dust on the spot that was rubbed but once you clean that off there won't be any scratches or discolouration.
In addition to all this, I learnt that a gold chain I've had since I was in primary school which I believed was 22k gold, was in fact only 18k. I'm a little shocked by this. The crucifix, tho, is 22k.
I learnt that mum has sapphires and topazes set in white gold, albeit a lowly 9k (or 375 gold).
I learnt that "washing" and "polishing" are very different in the jewellery industry - washing is dunking in a cleaning solution and jostling the things around. Polishing is also known as plating and the process takes a little bit more doing. There is first a chemical dunk, then they replate the item with whatever metal it was made from - I sent in a pair of mum's diamond earrings and 2 diamond rings, and another 2 of my own diamond rings. That right there already cost me $200, even after he gave me one complimentary polish.
I learnt that it's the wearing of the jewellery that changes its colour, not the keeping of it. So if I replate a piece and never wear it, in 10 years time (my jeweller assures me) it will still look brand new, as if I had just brought it home from the store - shiny, unscratched, and in pristine condition.
I learnt that if I want a design in white gold but it's only available in yellow gold, I can have it plated at the point of purchase (and at no extra charge because #
complimentary). Which is what I am having done on a new link bracelet I acquired today - to hold all my pendants. I'm making a charm bracelet out of pendants that I don't wear anymore. Because #
skintags. I haven't worn a necklace in a very, very long time. If I do wear anything around my neck at all, it's a string of pearls. No chains. No chokers.
I learnt that the lobster clasps that will be attached to said pendants will also be made of 916 gold and since each one is about half a gram and I'll need 6, I will actually have 3.3 extra grams of resaleable and trade-in-able gold on that bracelet.
I learnt that this is called a lobster clasp -
I learnt that 3.3g of gold is pretty costly. About $345 USD.
I learnt that they can turn stud earrings into dangling hook-type earrings. I got them to convert the
garnets (Christmas 2013!) and topazes (mum's) for me for a hundred bucks. Considering they're essentially resetting the pieces in 18K white gold, I suppose it's only fair that I pay for the metal and not just the labour-cost. (He advised against doing the same thing for the sapphires as the stones were a little bit too tiny. I guess I'll just have to wear them as studs... if I wear them at all. But 2 out of 3 ain't bad!)
They'll look something like this -
I'm also getting a ring knocked back into shape (I've worn that one for so long it's practically an oval now), having mum's old chain and a pair of earrings polished (yes, that means they'll re-dip it in white gold!) and waiting on that bracelet and 3 of the 6 lobster clasps to be plated (my pendants are mixed colours) and for the claws to get attached so that my pendants can be turned into charms. I'll show you the before and after when I've collected it in 2 weeks' time.
I also learnt that resaleable gold is always handy when you want to buy new gold. I traded in an old chain for $400 dollars to offset the cost of the new bracelet and clasps. Total damage after trade in - a little bit over $850.
And so after spending two afternoons at the jeweller's I've finally sorted out all my old jewellery, figured out all of mum's jewellery, and made wearable all the stuff I want to keep but don't already wear. I've also earmarked pieces for selling to the pawnshop, found a way to rescue the mama's gemstones, and have gotten rid of bits that are essentially worthless.
I feel very adult. This was the first time I'd ever gone and done jewellery things on my own. EVER. IN MY LIFE. I've only ever shopped for this stuff with mum.
Yup. I feel like I've gotten there. Adulthood.
Have some paper chips today.... after spending all that money, this is about all I can afford now :)
