Transparent Gem Size Reference Ruler

Preview gemstone shapes and apparent sizes in a jewellery design with a transparent reference ruler.

✅ Compare a visible size against the design - Printed guides show example gemstone outlines in different reference sizes.

✅ Keep the area below visible - Transparent material lets you hold the ruler over the design.

✅ Compare different outline shapes - Round, oval and princess-style references provide more than one shape to review.

Use the Guide for Visual Design Planning

Position the reference over the area you are designing and compare the printed outlines with the intended setting. The transparent format helps you keep the surrounding design in view during the comparison.

Choose the displayed option for the shapes you need and remove any protective film before use. The guide is a visual reference rather than an instrument that measures gemstone weight.
