Circa 1920 Diamond and Synthetic Ruby Floral Openwork Ring
A quiet dialogue of light and colour: two old mine cut diamonds rest at the ends of an openwork plaque, while smaller rose-cut and senaille-cut diamonds trace its scrolling flowers. A curved ribbon of synthetic rubies lends the design a graceful line of colour. Made around 1920, it retains the airy elegance of a jewel conceived to be admired close at hand.

Rose-cut and senaille-cut diamonds are traditionally described by number rather than by estimated weight, colour or clarity. Their irregular proportions—often compounded by closed settings—make reliable weight estimation and standard grading
impracticable while mounted.
To preserve the integrity of the ring and its settings, the diamonds were assessed while mounted and were not removed for weighing or grading; stated weights, colour and clarity are therefore approximate.
Adin individually screened every diamond in this ring using the EXA Natural Diamond Detector developed by Magilabs; each test returned a natural-diamond result.
