*The above prices (tax included) are for reference only and are not guaranteed selling prices. In addition, depending on the age of the certificate and the issuing organisation, the 4Cs details may vary, resulting in differences in price simulations.

Items Not Included in the Simulation

For diamonds of carat weight other than 0.3-10.99ct or diamonds with colour, clarity, and cut that are not available for selection in the simulation, please contact us for more details. If the 4C evaluation is known, we can check the market price and notify you by phone or WhatsApp.

Precautions Regarding Selling Diamonds
  • Diamonds with inclusions, lack of shine or cloudiness may result in a lower evaluation.
  • Even without colour indications, diamonds with brown or yellow tints may result in a lower evaluation.
  • The evaluation will differ depending on the carat weight, even if the diamond grade is the same.
  • Other factors, such as the treatment and condition of the item, will result in a difference in evaluation.
  • The market price list is based on the GIA's current grade.
Precautions Regarding Selling Gold and Precious Metals
  • If the item's grade is unknown, we may ask you to leave the product with us temporarily to allow us to examine it accurately.
  • Due to the influence of the gold and platinum market, prices may fluctuate even within the same day.
  • The market selling price does not include handling fees. We will inform you about the handling fees at the time of the appraisal.
  • Once sold, items will not be returned.

Diamond Evaluation Criteria

What are the"4C" criteria?

CaratCarat

A diamond's carats are determined by its weight: 1ct = 0.2g. Since the rarity and value of diamonds depend on the size of the rough gemstone, even if the weight is the same, a single large diamond is worth many times more than the sum of several diamonds. However, the evaluation is not based on a simple "bigger is better" scale but results from the conjunction with the other 4C criteria.

ColourColour

The colour category of a diamond is determined by its degree of "colour" (colourlessness). There are 23 possible ranks, the highest being "D," the first letter of the word "Diamond." The closer the gem is to colourlessness, the higher the evaluation; as the rank decreases, the yellow hue in the gem becomes more intense.
*During a diamond's crafting process, other components may affect the carbon atoms, resulting in a variety of colours: such "coloured diamonds" may gain remarkable rarity and value, depending on the final colour.

ClarityClarity

The "clarity" criteria judges a diamond's transparency. It measures the size, number, and nature of inclusions, cracks and fissures that affect a diamond's appearance. The size, number, nature, shape, and location of inclusions, cracks, and fissures examined under 10x magnification and rated on a scale of 11.

CutCut

A diamond's "cut" refers to the "polishing technique" of the crafting. Unlike the other 4C criteria, the cut is not based on the value of the rough gemstone but on the craftsman's skill. A diamond's brilliance is further enhanced by its shape, determined through calculations based on optical science. The evaluation of the cut is determined by the "proportion factor," "finish factor" (symmetry) and the "polish," rated mainly on a scale of 5.

About Icons

The manufacturing and distribution process for brand products emits large amounts of carbon dioxide (CO2) and consumes large amounts of water. The images below represent the amounts of carbon dioxide and water consumption that can be reduced by reusing a product.

Carbon Dioxide (CO2) Reduction

Carbon Dioxide (CO2) Reduction

Carbon Dioxide (CO2) Reduction

CO2 reduction expressed by the amount of CO2 absorbed by a cedar tree annually.

Water Consumption Reduction

Water Consumption Reduction

Our Calculation Method

  • The 'Resale Impact' is not a display of an actual environmental reduction but rather a quantification of the environmental impact (CO2 emissions and water consumption) generated by the manufacturing and distribution process that can be theoretically omitted when a customer purchases a product we resell instead of a buying a brand new item of the same type. Since our calculation is predicated on the emissions in the omitted manufacturing and distribution process, actual reductions in environmental impact may differ from our projected estimate.

  • Since our company does not manufacture goods, our calculations cover any resold goods (watches, bags, jewellery (including bullion), apparel, and accessories).
    Our company does not check and verify the actual numerical value of each item's environmental impact (CO2 emission and water consumption) for our Resale Impact. Instead, we base our calculations on data from the LCA database "Gabi*" and estimate the total environmental impact of an item's entire life cycle, from the procurement of its materials to its disposal and/or recycling. Our calculations were overseen by a third-party consulting firm.

  • Discrepancies in LCA results may occur due to differences in calculation assumptions or deficiencies in the manufacturing process.

  • Due to revisions in calculations, the latest calculated values of products may differ from those shown on product tags, etc.

**GaBi is a software provided by Sphera Solutions GmbH that evaluates the sustainability of products' lifecycles.

Learn About Market Prices and Valuation! Diamond Selling Price FAQ

Is it possible to sell old or antique diamonds?

Yes, one of our target areas is old and antique diamonds. However, our appraisals are based on modern criteria, so the assessment of quality and selling price may differ from the original purchase price of the diamond.

Can I sell a diamond even without a certificate of authenticity?

Yes, it is possible to sell diamonds even without a certificate of authenticity. Our appraisal staff will confirm the quality of your diamond and offer you a corresponding selling price.

Is there anything I should bring with me when visiting for an appraisal?

If you still have a professional’s written appraisal for the piece you want to sell, please bring it. If you have a written appraisal, the 4 C’s used to assess diamonds, as well as with the grade will be included—having that information available will allow us to complete the appraisal in a timely manner.

What is the term “LDH” that I found in my diamond’s written appraisal?

“LDH” is an acronym that stands for Laser Drill Hole. This is a diamond repair technique that entails drilling a minuscule hole on the surface or into the interior of a diamond so that acid or other solutions may be poured in to erase scratch marks. The mention of this term in your appraisal indicates that this procedure has been carried out on your diamond.

What are the 4 C’s?

The 4 C’s stand for Carat, Cut, Colour and Clarity, four criteria that are used to assess the quality of a diamond.

Is it possible to get an estimate for a selling price over the phone (if I want to get an idea of the carat count, etc)?

Even if you are only looking for a rough estimate of a diamond’s carat count, it would be difficult to determine the quality of a diamond without seeing it in person, so we are unable to provide this service at the moment. However, we are able to provide assessments of quality that include carat counts as well as selling prices to our customers who visit us in person, so please consider visiting an ALLU location for an assessment.

If I tell you the size of my diamond in millimetres, can you tell me the carat count?

Because a diamond’s carat value is calculated by weight, not size, we would be unable to inform you of its carat count based solely on its size in millimetres. If you visit us in person, we can tell you the carat value and an assortment of other information included in our appraisal, so please consider visiting an ALLU location.

What are melee/pavé diamonds?

Melee or pavé is a term ascribed to diamonds with a measure of less than 0.1 ct. At ALLU, we welcome jewellery featuring pavé diamonds, so if you have any such pieces, please consider bringing them in.

Do you buy loose diamonds?

Yes, loose diamonds are one of our target areas at ALLU, so please bring them in.

What items can I sell for a high price?

ALLU offers premium selling prices for diamonds, especially those with a high 4C grade. As for jewellery, we buy gemstones, accent stones, accessories, and bullion and will provide detailed assessments for each item category.

Does the strength of the yen affect selling prices?

Because many diamonds and gemstones are imported from outside of Japan, foreign exchange rates do influence our selling prices. In the case of a weak yen, market prices and pre-owned market prices will increase, leading to increased selling prices at ALLU.

I have a diamond necklace made of gold—would you also offer appraisals for the gold necklace part and not just the diamond?

Yes, we will take into account the various parts of any item, both precious metals and gemstones, and offer a selling price based on the values of every component.

Can I get an appraisal for my diamond via WhatsApp?

Yes, if you would like an appraisal for your diamond via WhatsApp, please send us a picture of your diamond as well as a picture of its written appraisal document. We will reply with a rough estimate for your diamond.

In what ways can I sell my diamonds?

We offer several appraisal options when buying customers’ diamonds: we conduct in-person appraisals at our stores, as well as appraisals by mail and even can send representatives from ALLU to conduct an appraisal at locations other than our stores, so please feel free to utilise these various options. ※ Please understand that diamond appraisal via online video calls are unavailable due to the difficulty of assessing the quality of a diamond without being able to see it in person.

ALLU Frequently Asked Questions

Can I sell items that are broken or in poor condition?

Yes, we can often purchase such items.

Items that are worn
Items that are scratched or dirty
Items with missing gemstones
Items with older designs

If you ever were refused by other stores when trying to sell your item for reasons such as the above, please visit us at ALLU.

Can I still sell items without a certificate of authenticity?

Yes. Even if you do not have a certificate of authenticity, our experienced Value Designers will carefully and accurately evaluate your jewellery.

Can I sell loose or rough gemstones?

Yes. In many cases — especially in the case of diamonds — if the grade is high, you can sell even loose gemstones at high prices.

Can I sell non-branded jewellery?

Yes, you can sell jewellery at ALLU regardless of the brand.

I received a higher selling price at another store.

We will do our best to meet your expectations, so please let us know how much the other company’s evaluation was.

Do selling prices vary from store to store?

No. All of our stores use the same standards for evaluation.

Do I need to make an appointment?

Yes. We ask that customers make an appointment via WhatsApp first so we can make sure that the appraisal can go smoothly.

How long does it take for an appraisal at the store?

We estimate 10 to 15 minutes for a single item. It depends on the item and the quantity, so please ask our staff when you visit.
