Is this diamond worh the price?

[Budding8]

Hi All,
I hope this is the best place to post this.

My Auntie is offering me a loose diamond with these stats for 4k AUD:

ROUND BRILLIANT

Measurements
6.19 - 6.27 x 3.77 mm
Carat Weight
0.90 carat
Color Grade
F
Clarity Grade
VS1
PROPORTIONS

Depth
60.5 %
Table
66 %
Girdle
Medium to Slightly Thick
Culet
None

FINISH

Polish
Excellent
Symmetry
Very Good

Is it worth it? How much will it cost me to set after I get the loose diamond?

Many Thanks,

Al

The table is larger than the depth on this diamond. That is generally not a good first impression.

Ideally, it would be good to also tell everyone the crown angle and pavilion angle too as we at least need those 4 numbers to get a general idea.

Ideally you'd like to look at diamonds in this range:

depth - 60 - 62% - although my personal preference is to allow up to 62.4%
table - 54- 57%
crown angle - 34- 35 degrees
pavilion angle - 40.6- 41 degrees
girdle - avoid extremes, look for thin to slightly thick, thin to medium etc
polish and symmetry - very good and above

Yikes! Unless that is a typo and the depth and table percentages should be the other way around. But on the current info, I'd be wary of this stone. Crown and pavilion angles would be good to know.

I'm curious where she got it and how much she paid...

I would also add that you really want to know if there is a lab report for this diamond (like GIA). Without knowing which lab graded it, it's hard for anyone to be sure if the color and clarity grade is correct and so it's hard to know if they price being asked is a "deal" or a dud. If this is an older stone, bought at a time when EGL diamonds were still being sold, then the color grade is probably off as well as the clarity.

If it is an ungraded stone, or EGL stone, then just for arguments sake let's say it's really an I SI, then here are some prices for well cut versions of those:

(and yours is does not fall in to ideal cut range) so let's look at a price of a "good" cut I:

https://www.jamesallen.com/loose-diamonds/round-cut/1.00-carat-i-color-vs2-clarity-good-cut-sku-2314366 )63 depth 60 table)

I advise extreme caution when buying "deals" from family members or friends.


Is your budget 4K AUS? There are a few Aussies here who can probably help with the conversion and duty tallies.... but....

here are some well cut, correctly graded F's below $4K

Didn't notice the reference to AUD in the OP's initial post until I read your 2nd response bunnycat.

If the OP is going to purchase from o/s and import into Australia, on a budget of AUD$4k, they will need to set aside around AUD$400-$500 to cover import surcharges levied by the shipping company, any duties and the 10% governmental goods and services tax, which means the OP will only have a budget of around AUD$3500 (but to be safe, I'd reduce that further to AUD$3400).

If the stone that the OP's aunt wants to sell to them however is in Australia, I wouldn't be too keen on it. The numbers as is already don't stack up. I'm not expecting to see a decent CA and PA.

Wouldn't surprise me if this an older stone that it is either an EGL graded stone or a stone graded by one of the myriad of Australian gem labs that used to be around based on some digging around I did a while ago on Australian gem labs.

Some of my work colleagues have said to me that they can get diamonds from an uncle or aunt that works in Hong Kong in the trade for wholesale prices. I essentially tell them, unless they have qualifications in gemmology, they really should stay away from these types of purchases from relatives or friends, especially if they come with appraisals or grading reports from labs few people have heard of.

Wow thank you so much for all the overwhelming info.

The stone is GIA graded and comes with an older type setting but I was going to just remove the setting and sell the gold to a the jeweler when I reset it? ( i know it's not worth much)

I'm not sure on the price and the 66% tabl. Do you have some pics?

Not a well cut stone. The table is way too big with no crown height.

Hi - the report doesn't have any further information. So no one is going to be able to make further commentary on the quality of the stone for you. It doesn't have a cut grade on the report (ie- excellent, very good, good, etc...) but with the table and depth listed, I would make a guess for "good" cut grade and here is a similar one with table and depth proportions like yours on James ALlen. About 4K and good, in this case, is not very good at all....

Now, if you have 4K to spend, would you rather get a well performing diamond? People here can help you further if you do because I don't think a 60.5 depth and 66 table is going to give you good performance and the stone will probably not look like a very nice F stone. I would wonder if it could possibly have a fish eye effect. If you watch the video of the JA diamond above, as it rotates you'll see this fuzzy ring form and disappear as it goes around. I believe that is the reflection of the girdle in to the stone (fisheye). Also, if you scale the video down to 1.5 (closer to life size) the diamond, when it faces full front, goes almost black all over from obstruction. I would use this video to see if you see similar effects in the stone you are considering.

Very old GIA report. No wonder it didn't have any other proportions on it nor a cut grade (from memory GIA only started issuing reports with cut grades from 2005 onwards). First time seeing a report that old so my initial surmising was entirely wrong.

To the OP: yes, you'd get back some cash from the sale of the setting but you are still losing out with a stone that is not well cut by PS standards. If you want to buy a loose diamond for AUD$4k and you are in Australia like I am, you either go through:
- a local diamond broker/seller (for example say DCLA Diamond Exchange),
- a local independent jeweller (not one of the chain stores like Prouds, Angus & Coote, Wallace Bishop, Salera's, etc),
- a local online vendor (Jogia Diamonds), or
- you go the oveseas option and buy through James Allen, Whiteflash, Brian Gavin Diamonds, etc.

The latter two options are much preferred in my books (even if you have to pay import duties, fees and taxes if you buy from overseas). You will be getting a much better cut stone.
