Round Brilliant Gemstones

The round brilliant cut is the most scientifically optimised shape for light return and scintillation. While originally developed for diamonds, the brilliant faceting pattern translates beautifully to coloured gemstones, producing exceptional sparkle and a lively, vivid colour display. Round sapphires, rubies, and tsavorites are particularly spectacular in this cut.

FAQs — Round Gemstones

Are round gemstones more expensive than other shapes?

Round-cut gems typically carry a small premium because cutting a round wastes more rough material than fancy shapes. However, the superior light performance often justifies the additional cost.
