What To Look For
The most valued spinel colors are the vivid reds and cobalt blues that remind us why spinel was once confused with ruby and sapphire. Although the most commercially important colors are red and pink, mauve- or lilac-colored gems are also attractive, and some blue spinel colors can be very valuable.
Spinel is most often cut in cushion and oval shapes. When properly proportioned it has excellent brilliance. Because of the scarcity of spinel on the market, most fine-quality rough is cut in non-standard sizes to save weight, instead of in standard industry sizes.
Spinel Quality Factors: The Comprehensive Guide
Tips & Advice
1. Understand the difference that color makes.
Look at different colors of spinel side by side to understand the range of qualities available. Pale colors are more affordable than vivid shades.
2. Don’t compromise on cut.
The quality of the cut can make a big difference in beauty and brilliance. Your spinel should sparkle in a lively way, reflecting light back evenly across the entire gem. Poorly cut gems are much less marketable and sell at a discount.
3. Work with a knowledgeable jeweler.
Because spinel is an unusual gem, make sure you choose a jeweler who has gemological knowledge and expertise.
4. When in doubt, get a lab report.
For a significant purchase, consider a report from an independent laboratory like GIA to confirm that the spinel you are buying is natural.
