Perpendicular Multi-Stone Jewelry Setting for Angle-Dependent Color Shift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The jewelry industry faces challenges in creating color-changing jewelry that enhances appearance without using rare and expensive color-changing gemstones or applying costly coatings, and existing methods do not allow for color change independent of lighting conditions or viewing angle.
Innovation Solution
A multiple stone setting where stones are set at a 90° angle on a base, with their center axes and girdles oriented perpendicular to each other, allowing each stone to display different colors due to inclination, independent of lighting conditions, creating three- or two-color changing surfaces that change with the viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If color changing gemstones such as alexandrite or synthetic stones are used, then color change effect is achieved, but cost increases significantly
Solution Approach 1:
The invention divides a single color-changing stone into multiple smaller stones (at least two stones) that are set in a jewelry article. Each stone may display different colors or color ranges, and when viewed together from different angles, they create the appearance of a larger color-changing surface. This segmentation allows the use of more affordable smaller stones while achieving the desired color change effect that would otherwise require expensive rare gemstones.
Solution Approach 2:
The invention combines multiple individual stones into a unified jewelry setting where the stones are positioned and oriented to work together as a single color-changing element. The stones are arranged with specific orientations relative to each other and to the viewer, creating a combined visual effect that mimics a larger color-changing gemstone. This merging allows the accumulation of color display areas while maintaining cost-effectiveness.
2Ease of manufacture
If a coating is applied to crystals to change color with viewing angle, then color change effect is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The invention extracts the color-changing function from the stone material itself (whether through natural properties or coatings) and relocates it to the geometric arrangement and orientation of multiple stones. Instead of relying on coatings applied to individual stones, the color display is achieved through the spatial configuration, facets, and angles of multiple uncoated or naturally colored stones, thereby eliminating the need for additional coating manufacturing steps.
Solution Approach 2:
The invention changes the geometric parameters of the stone arrangement, specifically the orientations and angles at which stones are set in the jewelry article. By adjusting these geometric parameters, the stones reflect and refract light in ways that create color changes with viewing angle, replacing the need for optical coatings while achieving similar or superior visual effects.
3Adaptability or versatility
If multiple stones are set to display different colors, then color variety is enhanced, but the setting complexity increases
Solution Approach 1:
The invention employs asymmetric arrangements of multiple stones with different orientations, facet configurations, and positioning angles. Each stone is deliberately oriented at specific asymmetric angles relative to the others and to the expected viewing direction, creating diverse color displays from a relatively simple multi-stone configuration. This asymmetric approach maximizes color variety while avoiding the need for overly complex symmetric patterns.

AI summary
A multiple stone setting (20) comprises a first, second and third stone (21, 22, 23) each set on respective plane surfaces (31, 32, 33) of a base (35) such that the second (22) stone is positioned perpendicular to the first stone (21) and such that the third stone (23) is positioned perpendicular to the first stone (21) and to the second stone (22), each stone (21, 22, 23) displaying a different color. As the viewing angle of an observer changes, each of the colors changes to a different color. A two-color changing multiple stone setting (70) is also disclosed. By providing multiple stone settings (20) and (70) three- and two-color changing surfaces may be created, respectively, that acquire an autonomous entity with changing viewing angles. Stone settings (20) and (70) may be useful to create articles of jewelry as well as to enhance objects and designs of various natures.
