Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.
What holds its value across Saint Laurent
- The Sac de Jour, Loulou, Kate and Niki, four bags with enough name recognition that buyers search them individually
- Leather biker and Le Smoking-derived tailoring, which are the house signatures and are bought as long-term wardrobe rather than as trend
- Aged-brass and matte-black hardware in unworn condition, since the finish is a large part of what buyers are paying for
- Pieces from the Hedi Slimane period, which are collected as a distinct era and priced separately from what came before or after
What pulls Saint Laurent resale value down
- Rubbed or brassed plating on the YSL cassandre logo, which is exactly where wear shows first and is the detail buyers photograph
- Stretched or torn chain-strap anchor points, a known weak spot on the chain bags and a costly repair
- Creased and softened lambskin on quilted bags, where the shape collapses and cannot be brought back
- Licensed eyewear and beauty-line accessories, which trade well below the leather goods regardless of the name
Identifying and dating yours
- A leather tab inside the bag carries a serial and a country stamp; photograph it along with the interior stamp on the lining
- The cassandre logo should be crisply cast with even spacing between the letters, which is what buyers compare first
- Ready-to-wear carries a season code on the interior label, which places a piece in the Slimane, Vaccarello or earlier period
What lifts any engagement ring, whatever the label
Second-hand rings sell well below their retail price, and understanding why is the most useful thing a seller can know before listing.
- An independent certificate for the centre stone
- Larger, well-cut stones with good colour and clarity
- A recognised maker, particularly with the original box
- A setting in current style that needs no rework
And what pulls one down
- No certificate, which makes buyers cautious about the stone
- Chipped or abraded stones, common on daily-worn rings
- Worn claws that need rebuilding before the stone is safe
- Very dated settings that a buyer would pay to have reset
Working out what yours is worth
- Find any certificate and note the stone’s carat, cut, colour and clarity
- Have a jeweller check the claws and confirm the metal
- Compare sold listings for a similar stone and setting rather than the retail price
What to state in the listing
- Metal and carat from the hallmark, and total ring weight
- Centre stone type, carat weight, and whether it is natural, lab-grown or a simulant
- Whether a certificate or valuation is included, and from whom
- Ring size, and whether it has been resized
Metal, stone and carat weight: “18ct White Gold Solitaire Engagement Ring, 0.5ct Diamond, Certificated”. The word certificated does a great deal of work if it is true. State the ring size, and if the stone is moissanite, lab-grown or cubic zirconia, say so in the title — not doing so is the fastest way to lose a sale at inspection.
Preparing and photographing it
- Find any certificate, valuation or receipt. A GIA or equivalent certificate transforms both the price and the speed of sale.
- Photograph the hallmark and weigh the ring, and note the ring size.
- Clean it gently, and examine the claws with a loupe or phone macro to check no stone is loose.
- The ring straight on, on a plain neutral background in daylight
- The centre stone from directly above, in focus
- The hallmark inside the band, legible
- The certificate if you have one, and the claws and setting close up
When it sells best, and handing it over
A slower, more considered sale than most jewellery, often several weeks. Certificated rings sell markedly faster. There is a modest lift before Christmas and Valentine’s Day.
High value in a tiny parcel. Confirm cleared payment first, use fully tracked and insured postage, and photograph the ring and the sealed packaging. Many buyers at this level prefer to meet, which is entirely reasonable.
What buyers ask
Which Saint Laurent bag sells best secondhand?
The Sac de Jour and the Loulou, both of which buyers search by name. Bags without a recognised model name compete against the whole designer market and sell for less.
Does worn hardware really change the price?
Yes, more than most sellers expect. The cassandre logo plate is the focal point of these bags, and brassing or scratching on it is the first thing a buyer looks for. Photograph it close up rather than hoping it goes unnoticed.
How much is a Saint Laurent engagement ring worth?
Roughly £180 to £2,160 depending on condition, against £100 to £1,200 for engagement rings generally. The identification points above are what move a listing to the top of that range.
