Product condition description/stone quality evaluation

Regarding the description of product condition

Condition evaluation will be on an 8-step scale.
Each piece is carefully polished by skilled craftsmen, and each item is left in like-new condition.

Most of the products in our store are second-hand items.
Depending on the customer, there may be ``dirt'' or ``scratches'' that may be of concern to the customer, so please be aware of this before purchasing.
Regarding the condition of the product, it may not be possible to show all scratches and damage in the image. Please note.
Please also note that colors may vary depending on the angle at which the photo is taken and the monitor of the computer or smartphone you are using.
Regarding products with gold stamps [Pm (Platinum)] and [18K/18kt/750] whose content has been confirmed, they will be written as [Pt900] or [K18].
Therefore, please note that the actual engraving and the description on the product page may differ.
Accessories (boxes, storage bags, etc.) cannot be included unless otherwise specified in the notes.
Please note that even "N rank" products (new) may not come without a box.
Although we naturally take product inventory management into consideration, the products posted on this site are also sold at our physical stores.
Therefore, please note that we may not be able to fulfill your requested order.

If you have any other questions, please feel free to contact us via the inquiry form, email, or phone.

Stone quality display is objectively evaluated based on the following three items.

rank	diamond
aaa	Top Colorless (Top Colorless) GIA standard D to E colors. It appears colorless and transparent when viewed from both face-up and edge-up angles.
aa	Colorless (Colorless) GIA standard F to H colors. When viewed face-up, it appears almost colorless and transparent.
a	Near Colorless GIA standard I-L colors. It looks slightly colored. Display the base color after the rank.
b	Very Light ~ Light color (Very Light ~ Light color) Below GIA standard N color. You can see that it is clearly colored. Display the base color after the rank.
c	Light color ~, below GIA standard S color. At a glance, you can see that the color is more clearly colored than the B rank. Display the base color after the rank.

rank	colored stones
aaa	The highest-ranking color tone among the target gemstones, such as pigeon blood ruby, cornflower blue sapphire, etc.
aa	Color tone next to AAA rank. There is a slight negative point when compared to the best toned ones. Example: beef blood ruby etc.
a	Normal rank color tone. Based on AAA, there are some negative points such as the color being a little light, dark, or dark.
b	The color tone clearly shows the negative points when seen with the naked eye. It's clearly a level where you're concerned about negative points such as colors being too light, too dark, or too dark.
c	Lower rank color tones that can be used as jewelry

Clarity is a standard for evaluating how relatively few scratches and inclusions there are.

rank	Content
AAA	Even with a 10x magnifying glass, inclusions are barely visible. (Clarity higher than VS class)
A.A.	When using a 10x magnifying glass, you can see slight inclusions. (SI1 class clarity)
A	If you look closely with the naked eye, you can see slight inclusions.
B	Several inclusions can be seen with the naked eye.
C	The presence of inclusions can be clearly seen with the naked eye.

rank	Content
AAA	The highest rank of brilliance among the target gemstones.
A.A.	Only when compared to AAA-ranked ones, you can see that the shine is slightly inferior.
A	It has enough shine and shine to be used as a jewel.
B	I can confirm that the texture is a little sweet.
C	It's cloudy and doesn't look very bright.

Depending on the nature of the gemstone, it may not be possible to express it using the 5-level rating above.
In such cases, the expression "A+" may be used.
If multiple pieces, such as melee diamonds, are used and there are differences in quality, the average quality will be displayed as the main one, and the quality of the range of use will be displayed in parentheses.
Display example: A(B+～AA)
The evaluation of brightness and shine may be due to the internal crystal structure or the quality of the cut and make-up.
Especially in the case of colored stones, there is no strict objective evaluation axis like that for diamonds, so please think of it as a somewhat simplified quality evaluation method to supplement photos and descriptions.

Please see below for the evaluation of graded diamonds that come with a certificate of authenticity and a sorting bag.

D～F	Colorless
G～J	Near Colorless
K～M	Faint Yellow Slight yellow
N～R	Very Light Yellow Very light yellow
S～Z	Light Yellow
color diamond	Fancy Yellow

F.L.	Flores completely intact
IF	Internally Flawless Minor surface scratches
VVS1, VVS2, VS1	Minute flaws that are difficult to detect even under 10x magnification
VS2, SI1, SI2	Can be detected with 10x magnification, but difficult to detect with the naked eye
I1, I2, I3	Inclusions can be seen with the naked eye
