User Guide

Search the entire collectibles market in one place.

ALT/FNDATA Market Search gives you a single window onto more than nine million auction and marketplace records across nine asset categories, from jewelry and gemstones to classic cars, fine art, and fine wine, spanning 2005 to the present day. This guide shows you how to find what you need and turn it into an answer.

1 Getting Started

When you first open Market Search you will see a brief welcome screen with a Get Started button. Clicking it takes you to our secure sign-in page, where you can log in or create an account. If you reach Market Search from inside the ALT/FNDATA portal, you are signed in automatically and go straight to the categories.

  1. Click Get Started on the welcome screen.
  2. Sign in with your email, or register if you are new.
  3. You return to Market Search with access provisioned automatically. No key to copy or configure.
💡 First-time visitors get a short guided tour of the interface. You can replay it any time with the Replay Tour button in the header.

2 Choosing a Category

Market Search opens on a category landing page: a grid of cards, one per asset category, each showing the category name and how many lots it holds. You start by opening one category at a time. This keeps every search fast and shows you only the filters, columns, and charts that make sense for what you are looking at.

Jewelry
~1.6M lots
Gems
~571K lots
Watches
~705K lots
Fine Art
~3.1M lots
Cars
~573K lots
Wine & Spirits
~812K lots
  1. On the landing page, click the card for the category you want.
  2. Market Search opens that category with its own filters, results, and (where relevant) charts.
  3. To switch, use the Data source selector in the sidebar, or return to the landing page to pick another card.
💡 The lot counts on the cards come from a precomputed summary that loads instantly and is refreshed twice a day, so the landing page is quick even before any search runs.

The nine categories

Each result card carries a thin colored bar along its top edge that tells you which category it belongs to. The colors are consistent everywhere in the app.

CategoryWhat it coversBar
JewelryDesigner and signed pieces, branded collections, mounted stones
GemsLoose and certified gemstones, unmounted stones
WatchesLuxury timepieces, vintage and modern
Works of ArtDecorative arts, objets d'art, sculpture
HandbagsCollectible handbags and accessories (Hermès, Chanel, and more)
CarsClassic and collector automobiles
MotorcyclesCollector and vintage motorcycles
Fine ArtPaintings, prints, photographs, drawings, sculpture
Wine & SpiritsFine wine, whisky, champagne, and other spirits

3 Keyword Search

The search bar at the top of the results area matches your words across the fields that matter for the open category, including the item title, maker, artist, producer, vendor, model, and sale title, along with gem type, origin, and color for gem-bearing categories.

How multi-word search works

Each word is matched independently and then combined with AND logic, so every word must appear somewhere across those fields.

Examples

In Fine Art, picasso lithograph 1960 finds lots where one field contains "picasso", another "lithograph", and another "1960".

In Cars, ferrari 250 spider narrows to a make, a model line, and a body style at once.

In Wine & Spirits, macallan 1926 pairs a producer with a vintage.

Synonym expansion

For gem-bearing categories the search bar expands common terms into multilingual equivalents automatically. Searching "ruby" also matches "rubis" (French) and "rubino" (Italian), and origin names expand too, so "Burma" also finds "Myanmar". Searches are always case-insensitive. Press Enter to run a search, or click the blue Search button that appears at the lower left whenever your filters change.

4 Filters

The left sidebar holds collapsible filter groups. Open a group by clicking its header, set your values, and the choices appear as removable pill tags above the results. The key thing to know: the filters adapt to the category you are in. A handbag search never shows carats or clarity, and a wine search never shows transmission.

💡 Filters do not run automatically. After changing anything, click the blue Search button at the lower left, or press Enter in the search bar. Use Reset all filters at the top of the sidebar to start fresh.

Filters available everywhere

FilterTypeHow it works
Date RangeDate pickersNarrow by sale date with a start and end date.
Sale Price (USD)Range slider and textDrag the handles or type exact values. Applies to sold lots.

Lot StatusMulti-selectSold, Unsold, Upcoming, or Withdrawn. Each option groups its related sub-statuses.

Filters by category

On top of the shared filters above, each category adds its own. The lists of choices are populated from live data the first time you open a category, so they reflect what is actually in the market.

CategoryCategory-specific filters
Jewelry, Gems, Watches, Works of ArtThe full set of gem filters (see Refine by Gem Details), plus Designer / Brand for jewelry, watches, and works of art.
HandbagsDesigner / Brand, Material, Item Type.
CarsMake, Year, Transmission, Fuel Type.
MotorcyclesMake, Year, Transmission.
Fine ArtArtist, Medium, Art Movement, Year.
Wine & SpiritsProducer, Alcohol Type, Year (vintage).

Refine by Gem Details

In the gem-bearing categories (Jewelry, Gems, Watches, Works of Art) a Refine by Gem Details button sits above the results grid. It opens a popup that gathers the stone-specific filters in one place. This button and its filters are hidden in the non-gem categories, so they never clutter a car or wine search.

Gem filterExample values
Primary GemDiamond, Ruby, Emerald, Sapphire, Pearl, Spinel
Gem TypesEvery stone in a lot. Multilingual, so "Ruby" also matches "Rubis" and "Rubino".
Gem OriginKashmir, Burma, Colombia, Ceylon, Mozambique, Madagascar

A numbered badge on the Refine button shows how many gem filters are active. Click Done to close the popup, then Search to apply.

5 Understanding Results

Every lot appears as a card in the results grid. Cards show the lot image when one is available, and a neat placeholder icon when it is not, so the layout stays even.

What each card shows

Cards adapt their tags to the category, surfacing the attributes that describe that kind of object.

CategoryTags on the card
Jewelry, GemsGem type, carat, color, origin, cut, clarity, designer, item type, and certificate.
WatchesDesigner, model, reference, year, case size and material, movement.
Works of ArtArtist or maker, item type, year, and any gem set.
HandbagsDesigner, material, item type.
Cars, MotorcyclesMake, model, production year, transmission.
Fine ArtArtist, medium, item type, year.
Wine & SpiritsProducer, vintage, type.

Pricing information

For sold lots, cards show up to three layers of price:

  1. USD price. The realized price converted to US dollars using the nearest-date exchange rate, so figures are comparable across houses and currencies.
  2. Local currency. The original sale figure in its own currency (for example CHF, GBP, HKD, or EUR) shown alongside.
  3. Price per carat. Calculated automatically for gem lots when both carat weight and USD price are present.

For unsold or withdrawn lots, the estimate range is shown instead of a realized price.

Status badges

Each card carries a status badge:

Sold Unsold Upcoming Withdrawn

Withdrawn and passed lots are shown at reduced opacity so they stay visible without competing with realized results.

Repeat lots

In Jewelry, Gems, and Watches, some pieces come to auction more than once. When a lot has prior sales history you will see a link such as "2 prior listings" on the card. Click it to open every recorded appearance of that item, with prices and dates, which is a fast way to see how a piece has performed over time. The Repeat lots toggle in the sidebar narrows results to only those with prior history.

6 Statistics & Charts

Four summary cards sit above the results, showing headline figures for the open category:

Total lots
2,773,498
Total value (USD)
$157.5B
Avg sale price
$105,174
Highest sale
$450.3M

With no filters set, the cards show precomputed totals for the category that load instantly. Once you filter, they update to describe your subset. These figures are refreshed twice a day.

Charts

For the gem-bearing categories, a set of interactive charts appears between the stats and the results, tracking average price and price-per-carat over time by gem and by origin, with every stone plotted on a scatter view. Hover a point for its details, click a legend entry to isolate a group, and use the expand icon for a fullscreen view. The charts are specific to stones, so they are not shown for cars, wine, handbags, or fine art, where they would not apply.

10 Getting the Most Out of It

Market Search is built to answer real questions quickly. Here are a few common workflows.

Price and appraise an item

Open the item's category, search its maker and model or gem and weight, set Lot Status to Sold, and sort by Most recent. The USD prices and price-per-carat give you an evidence base in seconds.

Find comparables

Narrow with the category filters (make and year, artist and medium, producer and vintage, or gem, origin, and carat) to build a tight set of like-for-like lots, then save it as a view to revisit.

Track a market over time

In a gem category, use the trend and scatter charts to see how price-per-carat has moved by gem and origin. In any category, filter to a segment and read the summary cards for its total value and average.

Research provenance

For jewelry, gems, and watches, open a lot's prior listings to trace every time it has come to auction, with dates and prices, and see how the piece has held or grown in value.

💡 Prices are always shown in USD for comparability, converted at the nearest-date exchange rate to each sale. When you need the original figure, it is displayed next to the USD price.
