I was looking for Tavernier's law. Thanks!
Glad to be of service
You are amazing! Anybody should have watch you just for learning all the interesting facts you add to the material you are discussing!
Thanks for the high praise Ellie~
I'm Donna Chassie.
Thank You, Peter Nelson A.G. I've been Culturally Enriched.
I rest my chin, on the heel of my hand, listening to all Your information on faceting. I'm just learning. Thank You.
Hi Donna~ welcome to the channel. I'm glad that my work has been culturally enriching for you ^_^
I giggle. I have my new Vevor facet machine. I haven't cut my first stone, but I'm organizing. Thank You, Peter, for Your help. Donna Chassie
Thank you, Peter. I love the information you are sharing. And especially how you do it! Quite fun and unique, I love watching you.
ditto
Agree!
I noticed this when looking for a nice flawless zircon for my wife I wanted over 5ct and the price really jumps when you get up into the larger stoves. I ended up with a 8ct amazing blue oval zircon set in an 18kt gold pendant and chain. Such an under appreciated stove.
Zircon is indeed striking. I have some colleagues that believe that zircon (beyond only blues) stands to grow in popularity (and therefore value).
@@GemologyforSchmucks it’s definitely on my radar as a new gem cutter and collector. I’m impressed you responded to a comment on a 3yr old video, thank you
I love how much I learnt in this video, you’ve sparked a lot of curiosity in me!
I'm tickled pink to have played a part in sparking curiosity. Cheers
Much appreciated Peter, thank you very much. You have a very learnable and easy to understand way of K.I.S.S. You've got a great gift for being able to teach kindly to us, what probably seems like to you a mundane idiot gemology trivia without making me feel like the childlike, ignorant, buffoon that I was before you taught me a carat is equivalent to 20/100 gram or 1/5 gram...#patonyourback and many thanks :)
It's an honour to receive such high praise, Be Reel. Thanks very much, and I strive to do better. I'm glad you enjoyed~ Have a great weekend.
you're welcome Peter, and you too as well.
Thanks for making a very informative video. Love your attitude :)
My pleasure Jason ~ i'm glad you're enjoying it.
I like this.
This is a wonderful short study.
I’m going to Cambodia next year, should I be skeptical of any gemstone?
I’m leaning towards red sapphires. Will I have any trouble shipping it back to U.S?
Hi Dan, Cambodia can have red corundum (ruby) though they're certainly less common now. Much of the material has been devoured by the market, so you should definitely be skeptical if you see high quality bright red pieces showing up. Flame fusion synthetics are just soooo cheap to produce, and the temptation for fast money is great. Zircon is a much more common stone to see out of Cambodia these days, so that would be worth looking for. If you've got a year to play around before you go, you might look at getting a handheld spectroscope and getting proficient at using it. Its a pretty effective tool for identifying zircon.
Shipping back to the US isn't a problem. As long as it is a loose gemstone, whether cut or rough, it is supposed to be import duty free as long as it is labeled correctly.
that 诶你好(anyhow) gave me a real good laugh!! 你好呀哈哈哈！and i love watching all of your videos thank you for these fun classes!
😂 我的荣幸～ 多谢支持🙏
Poke that algo! 🎉 great knowledge.
Thanks for participating ;) welcome to the channel.
thanks
My pleasure
Seriously cool that you speak Chinese
Thanks ~ it's one of the challenges in life that i'm most honoured to have gone through (/be going through).
Can you do an episode about calibrated stones, what it means, common sizes etc.
Yes absolutely, and I have~ I'll put a link below.

One more addendum, calibrated stones "theoretically" means that stones are all the same dimensions. Functionally this is untrue much of the time. "5x7 emerald cut" is supposed to be a calibrated size, but if you don't measure them before you buy... you're likely to get a wild variety. As the wise folk say: "You get what you inspect, not what you expect."
@@GemologyforSchmucks thank you! I truly appreciate what you do sharing all of this info with everyone and the fun that you bring to your video lessons. Truly an enjoyable watch every time.
If a D colour IF grade 1ct diamond costs 3000€ and a 2ct of the same quality is 18000€ the exponent of Tavernier's law is roughly 2.585.
Would it be possible to match certain exponents with certain gemstones of comparable 4C cut in their magic numbers? Or doesn't it follow such strict rules?
The exponent for topaz is probably just above 1 because it's so commonly available. And for ruby it's probably very high since one can get tiny beautiful ones relatively cheap whereas the bigger ones...
There are no hard and fast rules on pricing - it changes according to the normal economic rules of supply and demand. The highly rare and beautiful are the ones that usually migrate to being the most valuable (not always though). There are some stones that are more in demand because the supply is more predictable.
@@GemologyforSchmucks Thank you, I probably have to get rid of my engineering mind when it comes to the beautiful things...:)
@@shardana7422 You might be surprised~ that said, as I was speaking to another expert friend of mine who told me "My mind is melting and I'm having to unlearn everything" (rough quote) ... I think a little mind melting and unlearning is incredibly healthy. It keeps us nimble ~ cheers to you, and to us all.
@@GemologyforSchmucks Word.
The sort-of-square rule for carat prices works nicely in the other direction for industrial use. It would really suck if 200mg of fine diamond bits cost as much as a one-carot diamond, when you're just trying to make some drill bits.
I recently saw a website where cut cubic zirconias were given "carat" figures not by actual weight, but instead by the weight of a diamond the same size. So what they list as a "one carat" CZ would actually weigh around 1.6 carats, but it would be the same size as a 1 carat diamond. Is that a normal practice? I almost feel like this kind of works against the business, because their "cost per carat" for a CZ is going to look higher, since the carat weight is listed at a lower number than the actual weight.
Thats one of my favourite bits (sorry for the pun) of diamond history. Russians and Americans were competing to develop the first synthetic diamonds for these same industrial purposes. The costs for natural diamond coming from a monopoly or two were astronomical.
On the CZ thing, youre right that its somewhat deceptive, but it is fairly common with people dealing in diamond simulants (not me...) Some people want to look like they’re wearing a certain amount of value without actually having to pay for it. I get it, but it doesn’t excite me.
Overall, the price of CZ is so desperately low compared to diamond (even synthetic ones) so i think that the point is just to help convey a “size” and fulfill the dream of someone who has been enculturated to believe that diamonds are a girls best friend/ diamonds are success.
Coloured stone people tend to scoff at these lines bc we’ve been watching the price of average sized diamonds drop over the past near-decade.
Why have no colour when you could have... colour... :) thanks for the comment Tom.
@@GemologyforSchmucks Thank you for the response. I've just recently taken an interest in the topic so I've been on a bit of a deep dive.
Is there any vacancy related to Gemology?
If you are asking about jobs, you will need to shop around. Gemology is notoriously difficult for finding a traditional "job", but there are immense opportunities for those who will look with open eyes in places that others have not looked.
@@GemologyforSchmucks I am so curious to study about gemology. Your videos are helpful to us. Thanks a bunch 💎.......
And Thank you for your reply 😇😇
