About the price index Spike Earrings Anita Ko
Anita Ko's **Spike Earrings** are part of the house's signature vocabulary: geometric volumes, a contemporary interpretation of luxury jewellery, and wearability designed for everyday use as well as for stacking. The most accessible version in 14k gold is offered new at around 850 USD, while diamond-pavé variations rise to approximately 2,800 USD for the Spike Stud Earrings and 3,000 USD for the Six-Sided Spike Stud Earrings. On the pre-owned market in Europe, this positioning creates a consistent value, with an entry level around the simple gold pieces and a higher ceiling for diamond versions in excellent condition. The Spike Earrings sell well thanks to their recognisable design, wearable size, and Anita Ko's reputation in contemporary jewellery. The value depends primarily on the condition of the clasps and polish, the presence of diamonds, the gold purity, the rarity of the version, and the completeness of the original accessories.

Reading the Spike Earrings Anita Ko price guide
The range observed for Spike Earrings Anita Ko runs from €650 to €2,400, with a median of €1,450 — a 3.7× gap between entry-level examples and the most sought-after ones. That spread is normal: on this model, condition, material and year weigh more heavily than the reference itself.
In practice, a piece below the median usually shows accepted signs of wear or a common configuration; above it you find rare colours, precious hardware and complete sets with the original box and invoice.
What pushes the Spike Earrings price guide up
- Gemmological certificate and perfectly legible hallmarks
- Original stones, setting never reworked
- Box, warranty and invoice from the maison
- Identifiable collection, still catalogued or archived
Selling a Spike Earrings Anita Ko at the right price
We offer two options on this model. Outright purchase, settled within 72h once the piece is authenticated, suits anyone who wants an immediate exit. Consignment aims for the top of the range: the piece is photographed, promoted and sold with a commission that decreases with your membership card.
Signed jewellery keeps a floor value tied to metal weight and stone quality; the maison's signature and the presence of the certificate add the decisive resale premium.
How we authenticate a Spike Earrings Anita Ko piece
Every piece that joins Monogram Paris follows the same protocol in our Paris workshops: no catalogue photography, no supplier imagery, only shots of the actual item.
- Maker's and fineness hallmarks read under a binocular loupe
- Precise weighing and metal density check
- Stones: colour, clarity, cut and setting examined (certificate where available)
- Clasps, hinges and engravings compared with the maison's references
- Two expert sign-offs before the listing goes live
Care and storage
- Clean with lukewarm soapy water and a very soft brush
- Remove the piece before sport, swimming and household products
- Annual setting check for claw-set stones
Buy, sell or request a valuation
Two routes: outright purchase, paid within 72h of authentication, or consignment, with a commission that decreases with your membership card (25% Blanche, 22% Or, 15% Noire).
