Antique Buttercup Old Mine Cut Diamond Ring vs Antique-Style Diamond Semi-Mount Ring

The Antique Buttercup is a finished, wearable antique ring with a genuine old mine cut diamond, so it suits someone who wants a real vintage piece ready to wear. The Antique-Style Semi-Mount is a setting only: it needs a center stone set by a jeweler before it can be worn, and its 1 1/4 ctw figure counts accent diamonds plus a center stone that is not included. On build, the buttercup is a single small stone in 10K gold; the semi-mount is a larger, more elaborate setting with lab-grown accents. Buyers who want authenticity and a low-fuss ring lean to the buttercup; buyers who want a big, customizable antique look and will pay for a center stone lean to the semi-mount.

  • Choose the Antique Buttercup if you want a genuine antique ring with an old mine cut diamond that is ready to wear as-is.
  • Choose the Antique-Style Semi-Mount if you plan to source your own center stone and want a larger, customizable antique-inspired setting.

Questions and answers

Which is better for someone who wants a ring to wear right away?
The Antique Buttercup. It is a finished ring; the semi-mount needs a center stone set before it can be worn.
Is the semi-mount's 1 1/4 carat weight all diamonds in the ring?
No. That figure includes a center stone you supply plus about 1/4 carat of accent diamonds. The setting alone does not contain a full 1 1/4 carats.
Which has the better diamond?
They are different things. The buttercup has a natural antique old mine cut at I color and I1 clarity. The semi-mount uses lab-grown accents at G-H color and SI1-SI2 clarity, and the center stone quality is up to you.
Which lasts longer?
Both are durable gold settings. The buttercup's enclosed setting protects its small stone well; a semi-mount's longevity depends on the center stone and prongs your jeweler sets.
Is the semi-mount worth stepping up to?
Only if you want a larger, customizable antique look and are prepared to buy and set a center stone. For a ready-to-wear vintage piece, the buttercup is the simpler choice.
Can the buttercup be resized?
It is a 10K gold ring at size 5.75. A jeweler can usually resize it, but antique settings with detailed shoulders limit how far.
