Pearl Stud Earrings: Size, Grade & Metal Guide

This guide is written for buyers who need to choose a pearl size, a luster level and a metal before they place an order. It compares the size bands most often requested when retailers and distributors source wholesale pearl stud earrings, and it decodes the grading vocabulary that AAAA freshwater pearl earrings manufacturers publish on a listing. The documented reference point throughout is the 12–13mm freshwater pearl earring with 925 silver and a medium luster, because it is the band on this catalogue with a published, fully specified record.

Find Your Size Band First

Grade, luster and metal options change with the size you order, so the band is the first decision. Only the 12–13mm band has published specifications on this page. The remaining bands are catalogue ranges that buyers ask about most often; their grade, price and order terms are confirmed on inquiry, so you are never working from an estimated figure.

One row per band, so you can compare what is published and what still needs confirming. The 12–13mm row carries the live specification; the other rows list the checks that will be answered on request.

The listing states that the price is shown in USD and that the listed price does not include accessories. The specification table also lists a length of 39cm; if that measurement matters for your own product copy, ask the team how it is taken before you publish it.

Grading Decoder: What AAAA Means for Freshwater Studs

Grade language is only useful if it maps to something you can inspect. On this listing, four attributes carry the AAAA claim, and each one narrows what the buyer should expect from a delivered pair.

Luster

Medium

The listing records medium luster. Its advantage copy states that medium luster balances aesthetic appeal with production robustness, which is intended to reduce returns or quality complaints.

Shape

Perfectly-round

Roundness is listed as perfectly-round. That is the attribute that makes a stud sit evenly on the ear and pair cleanly with a second stud.

Blemishes

Little

Blemishes are listed as little, so expect small surface marks rather than a flawless skin. Set that expectation with retail buyers before launch.

Colour & surface

Natural

Colour is listed as natural. The listing states that AAAA grading certifies high pearl surface integrity and that natural authenticity is verified through the industry AAAA classification.

Pair-Matching & Uniformity for Studs

A stud is sold as a pair, so the pair is the product. When you review a sample or a delivery, run the same five checks every time and record the outcome.

  1. Sort by band before anything else

    Separate pearls into the size band you ordered — 12–13mm for the documented line — so pairs are never built across two bands.

  2. Calibrate size within the pair

    Measure both pearls and keep the pair inside one band. A visible size step is the most common reason a pair is rejected by a retail buyer.

  3. Match colour and luster together

    Natural-colour freshwater pearls vary slightly. Judge both pearls in the same light and in the same orientation before you accept the match.

  4. Inspect roundness and surface

    Confirm the perfectly-round shape and the little-blemish tolerance are consistent between the two pearls, not just on the stronger one.

  5. Check the mount, then apply reject criteria

    Review the 925 silver setting for seating and finish. Reject any pair with a size step, a mismatched tone, or a surface mark that sits on the face of the pearl.

Uniformity is the reason the listing positions this band as suitable for paired collections and modular assembly. If your range mixes studs with strands or necklaces, hold every station to the same matching rule so a set can be assembled from any two finished units.

Metal & Construction: 925 Silver

Metal is the field B2B buyers question most, because it drives wear complaints, returns and reorder behaviour. Here is what the listing states, and what still needs asking.

  • Which metal is used? The listed metal is 925 silver. It is the only metal recorded on the specification table for this product.
  • Why does 925 silver matter for durability? The listing states that incorporating 925 silver metal enhances structural durability and corrosion resistance. Treat this as the product page's stated advantage when you write your own copy.
  • What about posts and backs? The listing identifies the metal as 925 silver without naming a fitting style. If your market requires a specific post length or back type, confirm it on inquiry before committing to packaging or photography.
  • What does the 39cm length refer to? The specification table lists a length of 39cm. Because that figure is unusual for a stud earring, confirm what it measures before using it in your own listing.

Match the Order to the Specification

Four buying situations, four different decisions. Use the spec line under each card as the instruction you take to the supplier.

Single-pair retail or gifting

You are selling one boxed pair and the customer will compare the two pearls closely. Luster and surface consistency matter more than volume pricing.

Spec to request12–13mm freshwater pearl, AAAA, medium luster, perfectly-round, little blemishes, natural colour, 925 silver

Modular sets and paired collections

Studs have to combine with other units in the same band without looking mismatched. Uniformity is the buying criterion, not novelty.

Spec to requestRepeat the 12–13mm perfectly-round band across the range and confirm pair matching on every delivery

Wholesale restock and repeat volume

You need a line that can be reordered without reformatting your photography, packaging or price ladder.

Spec to requestStable inventory with flexible order quantities, dispatched in 3–5 business days from Hong Kong

Private label and custom design

You are building your own configuration and need the factory to work from your design brief rather than a stock SKU.
