Inverted Gemstone Setting for Unified Optical Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional invisible settings for gemstones do not offer a novel optical appearance when multiple stones are mounted contiguously, limiting their use in creating a cohesive, single large gemstone impression.
Innovation Solution
The novel setting mounts gemstones in an inverse orientation, with pavilions facing outwardly and crowns facing inwardly, concealed by the girdle, creating an invisible setting that can be used for multiple gemstones in a single or multiple rows, either all or alternate stones in this orientation, to produce a unified optical effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional invisible settings mount gemstones with crowns facing outwardly, then the setting is concealed by the girdle, but the optical appearance is not novel and does not create a unified single large gemstone impression
Solution Approach 1:
The patent inverts the conventional mounting orientation by mounting gemstones with pavilions facing outwardly and crowns facing inwardly, rather than the traditional crown-outward orientation. This inversion creates a novel optical appearance while maintaining the invisible setting characteristic where the setting remains concealed by the girdles, directly resolving the contradiction between conventional appearance and novel optical effect
2Strength
If multiple gemstones are mounted contiguously in conventional orientation, then they are securely mounted, but they appear as separate stones rather than a single large gemstone
Solution Approach 1:
The patent merges the visual appearance of multiple contiguous gemstones into a unified single large gemstone impression by inverting their orientation so that pavilions face outwardly and crowns face inwardly. The setting structure with prongs received in grooves formed in the crown and concealed by girdles maintains secure mounting while the inverted orientation creates the optical illusion of a single continuous stone, resolving the contradiction between secure separate mounting and unified appearance

AI summary
A novel setting for a gemstone (12) including a girdle (12g), a crown (12c) on one side of the girdle (12g), and a pavilion (12p) on the opposite side of the girdle (12g), characterized in that the setting (14) mounts the gemstone (12) in an inverted orientation by prongs (15) received in grooves formed in the crown (12c) of the gemstone (12) such that the pavilion (12p) faces outwardly of the setting (14) and the crown (12c) faces inwardly of the setting (14). Such a mounting is particularly useful when mounting a plurality of gemstones contiguously, in which case the prongs (17) mounting each gemstone (12) are concealed by the girdles (12g) of the gemstones (12). One embodiment is described wherein a plurality of gemstones (12) are all mounted in the inverted orientation with the pavilions (12p) facing outwardly, and another embodiment is described wherein alternate gemstones (32) are mounted in the inverted orientation with the pavilions facing outwardly, and with the remaining gemstone (33) being mounted in the normal orientation with the crowns facing outwardly.
