Duet Life Jewels™

The Duet process nestles two DNA strands together on one Helix to create a memento of a special bond. All Life Jewel designs  can be created as Duets. Each DNA is purified separately, enhanced with its own color, and placed on the same helix. The DNAs can either be next to each other with some blending in between (we call this style “side-by-side”) or intertwined. For the intertwined style we recommend that one of the DNA samples be enhanced with citrine, silver, or pearl.  The Duet option requires an additional DNA purification and special handling.

Color suggestions shown at right – from top to bottom: 1. emerald and citrine intertwined, 2. citrine and turquoise side-by-side, 3. turquoise and citrine intertwined, 4. jade and turquoise side-by-side, 5. pearl and jade intertwined, 6. silver and lapis intertwined, 7. silver and amethyst side-by-side, 8. silver and amethyst intertwined, 9. citrine and pearl intertwined, 10. rose and citrine side-by-side, 11. ruby and citrine intertwined, 12. pearl and ruby side-by-side. Please note that some colors work together better than others; use the examples at right to choose colors that will be attractive. Avoid combining dark colors together. Also – 23kt gold is not recommended for Duets as it has a heavier texture that doesn’t combine with other colors. Consider ordering citrine instead.
