What to look for in an antique diamond engagement ring?

Check the diamond cut and era, the metal and setting condition, and whether the ring can be sized to fit. Ask for an honest condition grade and authenticity guarantee. We provide all of this on every ring, along with complimentary sizing on most settings.

Are antique diamonds graded like modern diamonds?

Antique diamonds can be graded for color and clarity, but they were cut to different standards, so old mine and old European cuts are valued for character rather than modern brilliance. We describe each stone honestly and can discuss any available reports with you.

Are antique diamond engagement rings a good value?

Often, yes. You get hand craftsmanship, a genuine antique diamond, and a one-of-a-kind design, frequently for less than a comparable new ring. Value depends on the diamond, era, and condition, all of which we detail before you buy.

Can I wear an antique diamond engagement ring every day?

Many antique rings are well suited to daily wear, especially sturdy platinum and gold settings. Delicate filigree needs a gentler routine. We grade the condition of every ring and tell you honestly how it will hold up to everyday use.
