Buying Guide

Choose the right cut and shape

Cabochons, rounds, and rough stones perform differently in settings and wirework, so match the cut to your design and mounting method

Confirm gemstone type and origin

Look for listings that specify stone names like moonstone, tourmaline, rhodochrosite, or obsidian and disclose origin when possible for consistent color and quality

Check carat and count per lot

Many listings sell by total carat weight or 100 ct lots; verify piece counts and sizes to ensure you have enough material for your project

Prefer mixed-shape lots for variety

Mixed-shape and mixed-color assortments offer design flexibility for sample kits, while uniform cuts are better for matched pairs and sets

Inspect backing and finish

Flat-back cabochons suit glue-in settings and beadwork, while domed finishes are better for prong or bezel mounts
