FAQs – Raw Sapphires for Gemstone Cutters & Jewelry Designers
Q: Are these sapphires suitable for faceting?
A: Yes. Many of the stones have nice good color saturation, and minimal fractures—making them highly suitable for precision faceting or freeform cutting.
Q: What indicators should cutters use when selecting stones from this parcel?
A: Look for even body color, visible “windows” under backlighting, and cleaner zones within the rough. Stones with minor silk may also be useful for star sapphires or cabochons.
Q: What shapes are best for faceting this material?
A: Ovals, cushions, and emerald cuts work well. Some of the angular crystals can yield beautiful custom fantasy cuts too.
Q: How hard is it to polish these sapphires?
A: Sapphires are hard but polish to a high luster using diamond paste. For best results, use 8k–100k diamond on a tin or ceramic lap.
Q: Are these sapphires good for beginners?
A: Due to their hardness and potential for inclusions, they are better suited for intermediate to advanced cutters. Beginners should practice with quartz first before working on this parcel.
Q: Can these stones be used in raw or rustic jewelry?
A: Absolutely. The variety of colors and natural surfaces makes them ideal for bezel-set or wire-wrapped raw gemstone jewelry.
Q: Are there noticeable inclusions or flaws?
A: A portion of the lot may show natural silk, internal veils, or tiny cracks, which is common for raw sapphires. Select stones with cleaner zones for faceting.
Gem Cutting & Handling Tips
- For Faceting: Focus on well-shaped pieces with deep blue tones and few surface-reaching fractures.
- For Cabbing: Choose stones with silk or milky zoning for beautiful dome polish or potential star effects.
- For Jewelry Designers: Combine irregular sapphires with textured metalwork for an organic, luxury aesthetic.
- Storage: Use separate padded trays or gem jars to avoid surface scratches.
- Cleaning: Only use mild soap and warm water. Avoid ultrasonic cleaners unless the stone is inclusion-free.
Pro Lapidary Tips
- Always inspect rough under fiber-optic light or cross-lighting to map internal zoning and orientation.
- Use diamond wheels for shaping (start with 600 grit) and polish with 50k or 100k diamond paste.
- Keep sapphire cool while working—use water flow constantly to avoid thermal shock.
- If cutting for commercial sale, prioritize consistent color for pairs or calibrated shapes.
