Online jewelry store: purity, weight and a size nobody can guess

A jewelry store sells goods customers are afraid to buy blind: they are expensive, cannot be tried on and are inconvenient to return. What removes this fear is not the website's design but the accuracy of the data — the purity, the weight in grams, the item's dimensions in millimeters and a clear way to determine ring size. We build a catalog where this data lives in fields: the filter works on them, and customers use them to compare items and understand exactly what will arrive in the box.

Who it's for

Situations where this service delivers results

Scenario 1 of 4

A jewelry store with a physical location

In the store, customers get advice and can try items on. Online, the product page has to replace both: exact dimensions, weight and a way to determine ring size at home.

We'll review your situation in a free audit
What's included

Complete list of work and what you get as a result

  • a catalog with filters by metal, purity, stone type, size and purpose
  • a product page with the purity, weight in grams and item dimensions in millimeters
  • ring sizes as variants of a single product page, with separate stock for each
  • price recalculation by weight and metal rate, if that is how you work
  • a ring size guide explaining how to measure at home
  • availability display separating “in stock” and “made to order,” with the production time
  • checkout with Ukrainian delivery and payment methods
  • a technical foundation for search: structured data, breadcrumbs, canonical URLs, a sitemap
  • handover with a catalog description and rules for adding new items
When this service isn't right

What's not included — so there are no surprises at delivery

  • appraisal of items and gemological examination
  • photographing jewelry and editing the photos
  • paperwork for precious metals and stones
  • promises of search positions or a specific sales volume
  • shipment insurance — that is a contract between you and the carrier
Free review of your task

We look at what makes the jewelry niche distinct: data accuracy, sizes and a price that may depend on weight.

What we measure

  1. Whether purity, weight and dimensions are separate dataWhile they are text in the description, filtering and comparison by them are impossible — and these are exactly what customers choose by.
  2. How ring sizes are organizedSeparate product pages for every size bloat the catalog and hide the stock per model. Variants solve both problems.
  3. Whether the price depends on weightIf it does, you need a recalculation rule and a way to update prices when the metal rate changes — this affects the catalog architecture.
  4. What is happening with returns nowIn this niche, items are returned mostly because of size. Some of these cases can be eliminated with a size guide and exact millimeters before purchase.
  5. The technical state of your current websiteResponse speed, structured data, canonical URLs, breadcrumb markup — the same things we measured in stores in this niche.
  6. How availability is shownWhether the customer sees the difference between an item in stock and one made to order.

What you get

  • a list of what affects the result in this niche, with the reasons explained
  • a proposed catalog structure for sizes and stones
  • an estimate of the work broken down by stage
  • an honest answer as to whether you need this work at all

Timeline: 2–4 working days

Why is it free

A silver store with fixed prices and a store where the cost is calculated per gram can differ several-fold in the amount of work. Without a review, any figure would be guesswork.

What's next

You get a list and an estimate. Then you decide for yourself — the document stays with you either way.

What affects the price

Why two seemingly identical tasks are priced differently

  • Whether the price depends on weightPer-gram recalculation that accounts for the metal rate means separate pricing logic and a separate way of updating prices. This is the most noticeable difference in the scope of work in this niche.
  • Number of items with sizesRings and bracelets have variants; earrings and pendants usually do not. The larger the share of items with sizes, the more stock-keeping units there are.
  • State of the purity and weight dataIf the data is already in fields, filters are quick to build. If everything is text in descriptions, it first has to be broken out into fields, and that is a separate stage.
  • Made-to-order itemsShowing the production time and accepting orders for items not in stock requires a separate flow on the product page and in the cart.
  • Number of stone typesA stone filter is useful only when the names are consistent. Inconsistent spellings first have to be brought to a single list.
  • Readiness of photosIn this niche, the photo sells more than anywhere else. Inconsistent photos need to be put in order, and that is a separate scope of work.
Process steps

Transparent stages with approval at every step

Total duration:20–55 days

  1. Reviewing the task

    2–4 working days

    We look at the state of the data on purity, weight and dimensions, find out whether the price depends on weight, and count the share of items with size variants.

  2. Catalog structure

    3–7 working days

    We design the categories, the set of fields and the filters. We decide how to show ring sizes and how price recalculation will work, if it is needed.

  3. Building the store

    10–28 working days

    We build the catalog, the product page with purity, weight and dimensions, filters by metal and stone, and the ring size guide. We work in a test environment.

  4. Prices, stock and orders

    5–12 working days

    We set up stock tracking per variant and, if needed, price recalculation by weight, connect delivery and payment, and test the combinations.

  5. Technical foundation for search

    3–7 working days

    Structured data, breadcrumbs, canonical URLs, a sitemap, response speed. In the niche stores we measured, these were what was most often missing.

  6. Launch and handover

    2–5 working days

    We roll out the store, watch the first orders and hand over the catalog description. Then the 30-day warranty applies from the date the acceptance act is signed.

a sample of 4 Ukrainian online stores in the “jewelry” niche

Task
Find out what state websites in the “jewelry” niche are actually in, rather than taking their owners' word for it: the technical foundation, measurement and site size.
Solution
An external measurement without access to anyone's admin panel: time to first response as the median of several measurements, the catalog from the sitemap with URL deduplication, counters in the home page HTML, the PHP version from headers, hreflang, TLS, robots.txt and the canonical URL.
Result
Measured on 17 September 2026: 4 Ukrainian online stores in the “jewelry” niche were checked. 4 of 4 have no breadcrumb markup; 3 of 4 have no local business markup; 2 of 4 have no structured data; 2 of 4 have no canonical URL on the homepage. Median first response time: 584.0 ms; median sitemap size: 9,047 URLs.
What we need from you

We can't start without this — best to prepare in advance

  1. a catalog with purity, weight and dimensions in whatever form you have
  2. whether the price depends on the item's weight, and by what rule
  3. photos of the jewelry or access to the source they come from
  4. the delivery, insurance and return terms in your store
  5. which items are in stock and which are made to order
  6. who on your side accepts the work and can answer questions on substance
If something is missing — let us know, we'll help you gather it or do it as a separate task.
FAQ

Most frequently asked questions — with concrete answers

How will a customer determine their ring size without trying it on?

Through a size guide on the product page: how to measure a finger with a thread or a strip of paper, how to convert the circumference into a size, and what to do if the value falls between two sizes. This does not guarantee a perfect fit, but it noticeably reduces the number of cases where the size is chosen at random. Combined with exchanges, it is the cheapest way to eliminate some of the returns.

Our price depends on weight — is that possible on the website?

Yes, but it is separate logic: the price is calculated by a rule from the item's weight and the cost of the metal instead of being entered by hand. This has to be built in from the start, because converting an already populated catalog to this calculation costs more than designing it that way from the beginning.

Why put purity and weight in separate fields?

Because these are exactly what customers compare items by and base their decision on. As long as the purity sits in the description text, it is impossible either to filter by it or to compare two models. Besides, this data is needed for correct product markup, which search engines read.

How long does development take?

23 to 59 working days. The range depends on whether price recalculation by weight is needed and on the share of items with size variants. We give the exact timeline after the review.

Do you guarantee search positions?

No. Nobody who understands how search works guarantees positions. We are responsible for the technical foundation: speed, structured data, canonical URLs, breadcrumbs, a sitemap. In the stores of this niche that we measured, these were most often missing entirely.

Can we show items that are not in stock?

Yes, but they need to be honestly marked as made to order, with the production time stated. Mixing them with in-stock items in one list without a label is the easiest way to get cancellations and disappointed customers.

What happens after launch if something goes wrong?

A 30-calendar-day warranty applies from the date the acceptance act is signed: errors that are our fault are fixed free of charge. This is a clause in the contract. The domain, hosting and analytics are registered in your name.

Who owns the result?

You do. The property rights to the code, design and materials pass to the client after full payment, and the result is handed over under an acceptance act. The catalog description is handed over together with the access credentials.

There is no price list on the site on purpose: the same work differs several times over between two clients, and a “from” figure explains nothing in that case. First a free audit — we count your pages, duplicates and speed — then we name the sum and the deadline and fix both in the contract.
