Oval gemstones are the most popular shape in coloured stones, with a soft elongated outline that flatters the finger and keeps weight. You will find oval cuts here across many species, from sapphire and ruby to tourmaline and spinel.
How to choose an oval gemstone
- Pick a ratio: longer ovals look slimmer and more elegant, while rounder ones look fuller.
- Watch for a bow-tie: a dark band across the middle is common in ovals; a faint one is fine, a heavy one dulls the stone.
- Check symmetry: both halves should match when you look straight down.
- Use millimetres: length and width tell you how big the stone will look on the hand.
