Just want to say...

[im so scared]

This is the best diamond site on the web. Cant believe this existed for so long and I knew nothing about it. Further I want to commend the keepers and members of this post for

1) keeping adult chat topics off the site (usually there are a couple freaks that do that stuff on public non-adult sites)
2) the # of members and topics are staggering - also very quick turnaround!
3) very clean ergonomics on the page. easy to use
and . . .
4) no "superobvious" advertisement/emails.

THANKS

thanks for kind words

Leonid,

How can I find the relative rarity of a stone using your database? I want to know what percent of diamonds are AGS000 (or GIA ex/ex/ex)D-VS1 with no Fluor or better. HCA scope 0.8.

 

[pricescope]

I can run a query in my database, RS. It won't include HCA score though.

May I ask what is your interest?

 

[rsilvers]

I bought such a stone through your site, and want to know how rare it is so I can tell my girlfriend that the stone is 1:432 for quality. i.e. she can talk to 432 of her friends and only one of their stones is that nice.

OK here's the stats for D-VS1 rounds, ideal cut, GIA or AGS graded

count - polish – symmetry
-------------------------
118 ex ex
3 id id
-------------------------
121 total

ALL D-VS1 GIA and AGS graded rounds

count - polish - symmetry
-------------------------
77 n/a n/a
3 id id
1 gd fr
7 n/a gd
97 vg gd
55 gd vg
72 ex vg
48 vg ex
14 ex gd
116 gd gd
15 n/a vg
183 vg vg
118 ex ex
3 n/a ex
1 ex n/a
-------------------
810 total

Therefore, Id/Id and Ex/Ex are about 15% of all listed D-VS1 rounds.

we can check it in your carat range as well if you whish

 

[rsilvers]

I would like to subract out any "VG" as they are below this.

Also, IF/VVS1/VVS2/ should be counted as "better" so if I knew how many stones are the same or better then that would tell me if it is in the top X %.

The carat is 1.02 but I think I would like to leave this out because if we factor that in all we have to do is go by price! I would really rather leave it to "quality" rather than "value and total rarity"

Therefore, Id/Id and Ex/Ex are about 15% of all listed D-VS1 rounds.

The more interesting question (for me) is:

What percent of all diamonds sold in the last 2 years are (Id/Id or Ex/Ex) AND (color==D) AND (IF or VVS1 or VVS2 or VS1) AND have excellent cuts (table and depth within tight specs might be the only way to estimate this).

 

[pricescope]

all right.

there are 37375 AGS and GIA graded round diamonds listed with color D and less and clarity VS1 and less.

Rarity of your diamond comes to 0.32%

no can do

 

[rsilvers]

Wait -- not sure if that is doing it. I think it is fair to assume that 99% of EGL, IGI, or non-cert stones would not score as AGS000 because if they did they would have been submitted to AGS or GIA to be able to resell for a higher price in nearly all cases. So those should be included, no?

 

[pricescope]

You're right, RS. However, there are not too many EGL, IGI and other stones in the online database although probably there are quite a few in the malls

 

[golfer]

Leonid,

Where is this online rarity database?

 

[pricescope]

There is no "online rarity database", Golfer

I only have a diamond database and just ran a few queries

 

[rsilvers]

Ok -- thanks. So on your database, it is 0.3% (not counting size).

Now I wish I knew a way to include the mauls as there must be tons of stones sold there. Maybe Rappaport keeps those stats.

It is possible
