Diamonds are synonymous with enduring beauty and timeless appeal. In antique and vintage jewelry, diamonds often display earlier cutting styles—like rose cuts, old mine cuts, and old European cuts—that offer a softer, more romantic sparkle than modern brilliants. These stones were often set in platinum or gold and showcased in engagement rings, brooches, and earrings across all eras.

With vintage and antique diamonds, the "Four Cs" still apply, but character counts just as much as clarity. Older cuts may feature asymmetry or warmer hues, both of which are valued for their charm and authenticity. Check the condition of prongs, bezels, and settings, and look for hallmarks that indicate the age or maker of the piece.

Diamonds were favored throughout the Edwardian and Art Deco periods—often paired with platinum and millegrain detailing. Victorian designs may feature diamonds in closed-back settings, while mid-century rings and pendants embraced large stones and flashy cocktail designs. From solitaires to pavé styles, diamonds have been a constant feature in fine jewelry.

Diamonds are extremely durable but can still chip at the girdle. Store them separately to avoid scratching other pieces. Use a soft brush and gentle soap to clean settings, especially in filigree or pavé mountings. Regularly check vintage prongs for wear if the piece is worn frequently.
