About stone quality evaluation

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

  • This is Selby's own evaluation standard.

color evaluation

Diamond color evaluation

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.

Color evaluation of colored stones

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 evaluation

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

  • This is the same evaluation for diamonds and colored stones.
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.

Terri/brilliance evaluation

  • This is the same evaluation for diamonds and colored stones.
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.

About the evaluation of diamonds with certificates

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

  • The evaluation criteria will be determined by a third-party organization.

N~R Very Light Yellow Very light yellow
S~Z Light Yellow
color diamond Fancy Yellow

Jewelry that is often worn directly on the skin, such as rings, necklaces, and earrings, can become scratched, dirty, discolored, or deformed due to wear and age, no matter how careful you are.
At Selby, we carefully examine all of our products in-house, and we give used items a new finish before selling them so that our customers can use them for years to come.
Additionally, we accept unconditional returns for any reason within one week of purchase, so even those who are concerned about second-hand jewelry can purchase with confidence.

What is new finishing for jewelry?

Refinishing a piece of jewelry that has scratches, dirt, discoloration, or deformation involves correcting distortions and bends, checking stone clasps and decorative stones, cleaning the jewelry itself, and repolishing the metal surface. This is a process that brings back the shine to make it look like new.

New finishing process

  1. We will professionally check the entire piece of jewelry and mark any areas that need repair.
  2. The ring is inserted into a core metal (similar to a size rod), and distortions and bends are adjusted to balance the entire jewelry.
  3. We will inspect the stone clasp (the claw that holds the jewel), which is important in jewelry.
    Carefully tap loose nails and replace broken or worn nails.
    We will also replace any missing or missing decorative stones.
  4. If there are scratches or dents on the base metal part, after adding the base metal, smooth the surface with a spatula or router to make it clean.
    Also, polish the entire surface with a vinyl buff or board buff.
  5. The item is washed to remove dirt and inspected using a loupe or microscope.

At Selby, after giving new finishes to used jewelry, we take photos of the products and sell them.

Price of reused products

1. Buy reused jewelry

The most attractive thing about reused jewelry is the price.
The secret to its popularity is that it can be easily purchased for about 1/2 to 1/5 the price of a new product.
In addition, reusing allows you to encounter brand jewelry that has gone out of print and is no longer available as new, as well as jewelry with delicate forms that can only be expressed by hand.
However, there are cases where the seller sells the item without cleaning it (polishing, checking the nails and stones, etc.), does not have a certificate of authenticity or certificate of authenticity due to lack of knowledge about gemstones, or is refused maintenance. You want to pay attention not only to the temporary low price, but also to the reliability of the shop when purchasing.
Selby is a long-established reusable jewelry company that has operated physical stores in Ginza and Okachimachi as well as an online shop for 16 years since its founding.
We handle everything from strict product checks at the time of listing to after-sales follow-up after a successful bid.

No matter how much you use gemstones, their material value will never decrease.
In fact, the value of the material may increase due to rising market prices.

2. Let go of reused jewelry

The second charm of reused jewelry is actually when you let it go.
If you try to part with new jewelry, the appraisal price at the purchase store will be about 1/4 to 1/10 of the time you purchased it.
However, no matter how much you use your reused jewelry, as long as there are no significant fluctuations in gold or platinum market prices or exchange rates, you can collect your reused jewelry within 3/4 to 1/2 of the time of purchase.
If the market price of gold or platinum is higher than at the time of purchase, the appraised price may be higher than the purchase price.
Of course, just like when making a purchase, it goes without saying that it is important to choose a purchasing store that positively evaluates the value of the brand and stone.

Reused jewelry that has been well maintained will look just like new even when viewed by a professional.
The biggest advantage of reused jewelry is that you can get jewelry that looks almost the same as new, for about 1/2 to 1/5 of the new price, use it to your heart's content for years, and then sell it for the same price as when you bought it. This is the charm of
