SUNNYCLUE 1 Box 200Pcs 4 Styles Rhinestone Connector Charms Crystal Link Pendant Metal Flat Round Linking Birthstone Charm Connectors Review (2026)

What this box of connectors is for

SUNNYCLUE packages this set as one box of 200 flat round rhinestone connectors split across four sizes, with roughly 50 pieces of each. The listed dimensions run from 0.28 by 0.12 inch up to 0.43 by 0.24 inch, so the smallest pieces suit earring drops and the largest work as bracelet or necklace focal links. Each connector has two loops so it sits inline on a chain or cord rather than dangling like a charm. The rhinestone facing is designed to catch light the way a birthstone accent would, which is the angle SUNNYCLUE and most retailers use to market the set for personalized family or mother's jewelry, even though the piece is not sold as an actual birthstone gem. Buyers who want a fast way to add sparkle to plain chain without sourcing loose stones, bezels and glue separately are the target audience here, and the four sizes in one box mean you are not stuck restocking a single size before a project is finished.

Materials and construction explained

The connectors are built from an iron base metal finished in a gold tone, with the rhinestone facets set into the metal rather than being loose stones you set yourself. A 1mm hole runs through each loop, which fits standard jump rings, thin chain and most beading wire gauges used in commercial jewelry making. Because the base is iron rather than sterling silver or solid brass, the plating is thinner than what you would find on premium connectors, and iron cores can be more prone to tarnishing or a faint magnetic pull compared to brass or copper alternatives. The rhinestones themselves are glued into their settings rather than prong set, which is standard for this connector price bracket but does mean the stones are the weak point of the piece. The plastic storage box that ships with the 200 pieces keeps the four sizes separated, which matters more than it sounds since mixed loose charms in a single bag get tedious to sort by hand.

Using and caring for the connectors

Working with these connectors is straightforward: open a jump ring or thread beading wire through the loop, attach it between chain segments or beads, and close the link with flat nose pliers. Because the rhinestones are glued rather than prong set, avoid soaking finished jewelry in cleaning solutions, ultrasonic cleaners or harsh perfume sprays, since solvents can loosen the adhesive over time. Wiping the piece with a soft dry cloth after wear is the safer routine. Storing the connectors flat in the included box, away from humidity, helps slow tarnishing on the gold tone plating. Owners assembling bracelets or drop earrings should plan to reinforce heavily worn pieces with a thin coat of jewelry-safe sealant if they expect daily wear, since the manufacturer markets these as craft and gift jewelry components rather than fine jewelry built for years of everyday abrasion.

Trade-offs and how it compares

Against UNICRAFTALE's clear crystal connector pack, which ships around 140 pieces across seven styles, SUNNYCLUE trades style variety for a simpler four-size range and a birthstone-style color story that reads more cohesive in a finished piece. Compared with Fashewelry's round alloy link connectors, which are plain metal frames meant for UV resin or pressed flowers, SUNNYCLUE's rhinestone facing adds sparkle at the cost of being less useful for resin work. The main trade-off across this whole connector category is durability versus cost: glued rhinestones and an iron core keep the price low but will not hold up to the rough handling that cast sterling silver connectors tolerate. Buyers making one-off gift pieces or occasional-wear jewelry get good value here, while anyone building pieces meant for daily wear over years should budget for a sturdier, prong-set alternative instead.

Who should buy this and who should not

This set fits hobbyists and small jewelry sellers who want an affordable way to add rhinestone sparkle to bracelets, earrings and necklaces without buying stones and settings separately, and who are comfortable with the four fixed sizes covering most of their project needs. It also works well as a beginner-friendly component since no stone setting skill is required, just basic jump ring and wire work. Shoppers should look elsewhere if they need connectors rated for daily wear, since the glued rhinestones and iron base are better suited to gift pieces and occasional accessories than to jewelry that gets worn every day for years. Anyone with nickel sensitivity should also check reaction history carefully, since iron-core plated findings are not always labeled hypoallergenic the way solid brass or surgical steel pieces are.
