Solitaire ring: photo to 3D CAD, gold weight and price
The solitaire is the cleanest test of a setting: one stone, a band and prongs. Upload a photo and the studio gives you an editable model with the prong count, band width and stone size you can change one at a time.
The numbers that matter
- Prongs
- Four prongs show more stone; six hold a round more securely; bezels protect the girdle and suit active hands.
- Band width
- 1.8–2.2 mm is the common solitaire width; under 1.6 mm bends with a heavy stone.
- Head height
- Low-set stones catch less; a cathedral setting raises the stone and needs more metal.
- Weight
- A 2 mm 18K band, size 54, with a four-prong head weighs about 3.2 g; 14K about 2.9 g.
What the AI extracts
- Every component as parametric geometry: band, setting, prongs, halo, links, clasp
- Each stone group with cut, size in mm and estimated carat weight
- Metal colour and, where a hallmark or document shows it, the karat
- A gem report and a metal-weight table for 9K to 24K, platinum and silver
- A price estimate: new, pre-owned or to be made, natural or lab-grown, per country
Things you can say
- “Change to a six-prong setting”
- “Make the band 2.2 mm wide”
- “Set the centre stone to 1.2 ct”
- “Show the metal weights for every karat”
Frequently asked
- Can I see the gold weight before I order?
- Yes. The weight table shows grams, pennyweights and the price per karat and colour at today's spot, with a range for modelling uncertainty.
- What does a jeweller charge to make it?
- Choose “To be made” and a country: you get materials plus workshop time (casting, setting, finishing, CAD) at that region's rate.
- Can I export to STL for casting?
- Yes, STL and OBJ exports are available with credits; the model is watertight parametric geometry.
