About Onyx
Onyx is a banded variety of chalcedony, most commonly seen in fine jewelry as solid jet-black (often heat-treated to deepen the color). It's been used in jewelry, signet rings, and cameos for thousands of years and remains a staple of men's fine jewelry. Onyx scores 6.5–7 on Mohs (durable for daily wear) and contrasts strikingly against both yellow gold and platinum. Its even, opaque surface makes it ideal for engraving and inlay work.
About the Solitaire Setting
The solitaire is the most enduring engagement-ring silhouette — a single center diamond held by 4 or 6 prongs on a clean band, with no side stones to compete for attention. The classic six-prong 'Tiffany Setting' was introduced in 1886 and remains the reference design for solitaires today. A solitaire puts 100% of the visual focus on the center stone's cut, color, and clarity, which makes diamond quality particularly important. Solitaires pair cleanly with any wedding band style and are the most resizing-friendly setting category.
