A gemstone’s cut is what transforms it from raw material into something extraordinary. Even the finest color or clarity can be wasted if the cut isn’t right. For me as a gem cutter, this is where artistry and precision meet.
When you know what to look for, you can spot the difference between a gemstone that’s simply polished and one that’s cut to its full potential.
Symmetry
Well-cut gemstones are symmetrical. Facets should be evenly sized and aligned, with meet points (where facets come together) that look clean and intentional. If a stone looks uneven or lopsided, it usually means the cut was rushed or poorly executed.
Proportions
Proportions control how light travels through a gem. If a stone is cut too shallow, light leaks out the bottom and the gem looks flat. Too deep, and the gem looks dark. Balanced proportions return light through the top of the stone, giving it brilliance and life.
Polish
A high-quality gemstone should have a smooth, reflective surface on every facet. Scratches, pits, or a dull finish suggest poor polishing, which lowers both beauty and value. A well-polished gem should catch light effortlessly.
Brilliance and Sparkle
When a gemstone is cut correctly, it interacts with light in a dynamic way. Sparkle should appear evenly across the gem, not just in isolated spots. If you tilt the stone and it goes “dead” in certain areas, the cut may not be optimized.
Weight Balance
Sometimes gems are cut to maximize weight instead of beauty. This can result in overly thick girdles, uneven crowns, or awkward shapes. A cutter who prioritizes artistry — not just carat weight — produces stones that are balanced, elegant, and wearable.
Closing Thoughts
Cutting is more than shaping a stone — it’s unlocking its potential. Clean symmetry, balanced proportions, and a proper polish are what separate an ordinary gem from an exceptional one.
At Belliveau Atelier, every gemstone is chosen or cut with this standard in mind. Because in the end, value isn’t just about rarity — it’s about craftsmanship.
