FUTURE CHANGES ARE POSSIBLE ON DEMAND.

This 3D CAD model depicts an elegant and substantial ring, centered around a prominent, large rectangular gemstone identified as an emerald cut blue diamond. The central stone is secured by four classic corner prongs.

Complementing the main stone, the ring features numerous smaller round blue diamonds meticulously set along the shoulders of the band. These accent stones are arranged in a closely-set style, likely pave or shared-prong, extending down the sides of the ring's upper shank. According to the Gem Reporter in the image, there are a total of 64 round accent diamonds of various sizes, ranging from 0.80mm up to 1.90mm in diameter.

The Gem Reporter provides detailed information about the stones:

The main central stone is an Emerald Cut diamond measuring 10.33 mm in length by 7.32 mm in width. Its calculated weight is 3.34 carats.The surrounding smaller round diamonds total 64 stones. Their combined weight is calculated to be approximately 0.40 carats (3.74 ctw total - 3.34 ctw main stone).The total gem weight for the ring is 3.74 carats, comprising a total of 65 stones (1 central emerald cut + 64 round accents).The ring's band (shank) is solid and tapers slightly towards the bottom for comfort and balance. The model is clearly designed for metal casting, with the Metal Weights window displaying potential weights for various gold alloys (like 9K, 10K, 14K, 18K, 22K Yellow Gold and various White Gold purities), indicating the intended manufacturing method.

The precise dimensions of the model are crucial for production:

Central Stone Dimensions: 10.33 mm (Length) x 7.32 mm (Width).Ring Head Width (across the top, likely including prongs): 8.07 mm.Ring Head Height (above the finger/band): Approximately 4.93 mm (as indicated in the side view dimension).Ring Shank Width (at the shoulders): 1.89 mm.Ring Shank Width (at the base): 1.60 mm.Approximate Finger Size (Inner Diameter): 16.48 mm (This corresponds roughly to a US Size 6).Total Profile Height (from base of band to top of stone): 26.85 mm (overall vertical extent in the side view).In summary, this 3D CAD model is a blueprint for a luxurious ring featuring a dominant 10.33x7.32 mm emerald cut blue diamond of 3.34 carats, accented by 64 round blue diamonds totaling approximately 0.40 carats, all set in a classic metal band with detailed dimensions provided for manufacturing.
