JKEIO 925 Sterling Silver Adjustable 6-Claw Ring Base for 20mm Cabochon — Solid S925, Ready-to-Set

A solid S925 sterling silver, adjustable 6-claw ring mounting designed for fitting a 20 x 20 mm cabochon so you can craft a custom ring.

This JKEIO ring blank is a ready-to-set silver finding made from genuine 925 sterling silver and stamped S925 to confirm its composition. The open, adjustable band lets you wear it immediately and resize it for different fingers, while the six-prong head secures round cabochons, cabochon-style stones, or other rounded inserts. It ships as a single piece, ideal for hobbyists, small-batch makers, or anyone who wants to turn a raw stone or pre-cut cabochon into wearable jewellery.

How large a stone does this ring base accept?

The setting is built to hold a round cabochon measuring roughly 20 x 20 millimeters. The six-claw design surrounds the stone to keep it centered and stable once you press or glue the stone into place.

• Fits round cabochons about 20mm in diameter and depth up to typical cab sizes.
• Six prongs distribute pressure evenly around the stone’s edge.
• Compatible with smooth, domed stones, glass cabochons, and resin pieces.

Is the ring truly sterling silver and will it stay bright?

The piece is crafted from 925 sterling silver and carries the S925 hallmark as confirmation. Sterling silver can develop patina over time; with regular polishing or occasional professional cleaning it will retain its bright appearance for years.

• Stamped S925 to verify authenticity.
• Polishes to a bright finish and can be maintained with silver cloths.
• Solid silver construction rather than plated base metal.

How adjustable is the band and can it be resized safely?

The band is designed to flex slightly so you can slide it onto different fingers without tools, providing a comfortable fit for many sizes. For permanent resizing or heavy repeated bending, consult a jeweler to avoid stressing the metal or weakening the setting.

• Openable band fits a range of finger sizes for immediate wear.
• Gentle manual adjustment works for occasional size changes.
• Professional resizing recommended for permanent alterations.

What techniques work best to set my stone in this mounting?

You can secure cabochons with adhesive or by carefully pressing the prongs over the stone’s edge using bezel-pushing tools. The six-claw style pairs well with glue-setting for stable, low-profile designs and with prong-turning for a more traditional secured hold.

• Use strong jewellery epoxy or E6000 for glue-set cabochons.
• Employ prong-setting tools to gently bend claws over the stone if preferred.
• Clean both setting and stone before assembly for best adhesion.

Who is this ring base for? Makers of all skill levels will find this JKEIO 925 sterling silver ring blank useful: hobbyist crafters who want a high-quality foundation for a showpiece ring; jewellery designers prototyping new cabochon concepts; gift-makers assembling a personalised present; or small businesses producing limited-run handcrafted rings. It’s especially suited to projects that call for an authentic sterling-silver look, a secure six-prong hold, and the flexibility of an adjustable band.
