The spring colours are going to make an impact very soon. Most exciting for me are the purple based pastels that are due to have a major impact with styles this spring.
Soft violet is exciting for the various gem combinations available to every kind of jewellery artist.
Turquoise as a color opens up working with Turquoise as a gemstone this Spring. Aquamarine is a strong choice for this match as well if that's part of your gem line.
Yellow, of course, is the essence of Spring and Citrine and Amber will be leading the pack for up front designs with that sunny day appeal.
