A vintage 18k white gold engagement ring is the way to go. Budget friendly and starring a brilliant cut diamond of .10 carats (H-I color; VS2-SI1 clarity), graceful lines and open filigree work make this ring extraordinary for its cost.
This traditional diamond solitaire shows what good design is all about. The white on white color theme has the charming center diamond visually appearing greater than its stated size as the white gold bezel blurs the boundaries between it and the glittering diamond.
Attention to detail and delightfully airy open work provide a wonderful feminine presence for this ring circa 1950.
