  Have you ever noticed that your silver jewelry is stamped with S925 ? You might be curious about what S925 actually means on your jewelry. In fact, S925 indicates that the piece is made of sterling silver, containing 92.5% pure silver. Sometimes, you may come across jewelry marked with 925 instead of S925. So, is there a difference between S925 and 925? If you’ve been wondering about this, don’t worry — Starsgem is here to explain everything you need to know about these markings in detail! What Does S925 Mean on Jewelry? S925 is a jewelry marking that indicates a sterling silver alloy containing 92.5% silver by weight. The remaining 7.5% generally consists of other metals, most commonly copper. Pure silver is relatively soft, which makes it more susceptible to bending, scratching, and deformation in jewelry applications. By combining silver with a small percentage of other metals, manufacturers produce an alloy with improved hardness and strength. This makes sterling silver suita...

Quality Control Checklist for Wholesale Diamond Earrings Orders The short answer: A quality control checklist for wholesale diamond earrings orders is a documented, AQL-based inspection protocol that verifies stones, metal purity, setting security, finish, pair symmetry and packing against a signed specification sheet before a bulk shipment leaves the factory. Relevant specifications and application guidance are available through Product Categories . Earrings fail in ways rings rarely do. Two stones must match each other. Two posts must sit at the same height. A buyer often sees the goods for the first time after they clear customs, which means every check has to happen before the box is sealed — not after. A loupe and a hopeful handshake do not scale to 500 pairs, let alone 5,000, and they do not survive a chargeback. What follows is the working checklist for bulk stud, drop and hooped earring runs: six stages, the tools for each, the numbers that define a pass, and the mistakes t...

Prong, Bezel, and Halo Settings for Diamond Earrings Compared Introduction A prong setting holds a gem with claws of metal, a bezel wraps it in a continuous metal rim, and a halo surrounds it with a ring of small stones — three different answers to one question: how do you keep a diamond on an earring without hiding it. Buyers ask which is "best," and that question is badly formed. A 4-prong head on a 0.10 ct melee and a full bezel on a 1.50 ct stud solve different problems. One maximizes light return per gram of metal. The other maximizes retention and wearer safety. Compare them without first fixing stone size, cut, and wearing context and you get a tidy table that tells you nothing useful. This tutorial runs the comparison the way a production jeweler runs it: stone first, then retention, then proportions, then comfort and compliance, then cost. Work through the five steps and you can choose a setting for any earring SKU in a catalog and defend that choice to a retail...

How to Choose Diamond Necklace Length for Different Customer Segments Diamond necklace length is the finished, clasp-to-clasp chain circumference — measured in inches or centimetres — that decides exactly where a diamond or pendant rests on the chest. Move that single measurement by two inches and the same 0.50 ct stone reads as a delicate everyday piece on one buyer and an awkward, floating chip on another. Relevant specifications and application guidance are available through Color Diamond . Most sourcing sheets treat length as one line item: pick 16, 18, or 20 inches and move on. That shortcut collapses the moment you sell to more than one customer profile. A 22-inch chain that flatters a corporate gifting buyer is the wrong call for a 20-year-old buying her first pendant — and both differ again from a market where average female stature runs smaller or taller. This tutorial is for brand owners, sourcing managers, and product developers placing OEM orders. Starsgem, for referenc...
