Their clean lines complement both vintage and modern settings while providing excellent finger coverage in rings. Natural rectangular gemstones create a sophisticated aesthetic that balances tradition with contemporary style.

How does the rectangular cut affect a gemstone's value compared to rounds?

Rectangular cuts typically cost 10-15% less than round brilliant cuts of comparable quality, offering excellent value for buyers seeking maximum impact.
