Tiny Bow Diamond Stud Earrings – 3D CAD Model for Jewelry Manufacturing (STL, OBJ, 3DM)
*** All Files Types Include
Design Overview
The Tiny Bow Diamond Studs are a delicate, feminine earring design featuring a signature ribbon bow motif crafted from smooth, rounded metal loops. Each earring suspends a single round brilliant-cut diamond from the base of the bow via a small jump ring, held securely in a four-prong basket setting with a decorative gallery rail underneath. The design balances a playful, romantic silhouette with clean, wearable proportions, making it suitable for everyday wear as well as gifting occasions such as birthdays, graduations, and bridal party gifts. The model is shown in three finishes — yellow gold, rose gold, and white gold/platinum — demonstrating how well the design translates across common jewelry metals. Overall earring height measures approximately 10mm with a 9mm wide bow, and the featured round stone is sized at 4mm (approximately 0.24 carats per stone, 0.48 total carat weight for the pair), though the setting can be resized to accommodate different gem diameters.
3D Modeling Details
This is a native, manufacture-ready 3D CAD model built with clean, watertight, solid geometry suitable for jewelry CAM/CAD workflows. The file includes separately modeled components — bow top, jump ring, prong basket, gallery rail, post, and clutch/scroll back — allowing for easy editing, resizing, or material reassignment. Gem data is embedded and reportable (round brilliant, 4.00 x 4.00mm, 2 stones, 0.48 total carat weight), and the model has been tested against a metal weight calculator across multiple alloys, including 9K, 10K, 14K, and 18K white gold, sterling silver, and 10K rose gold, giving buyers accurate gram and pennyweight estimates for costing and quoting. The design is fully symmetrical for a matched left/right pair and includes accurate wall thicknesses and prong geometry to support real-world casting tolerances.
Manufacturing Suitability
This model is optimized for both traditional lost-wax casting and modern additive manufacturing workflows, including resin 3D printing for investment casting and direct metal 3D printing where available. The geometry has been checked for common production issues such as thin walls, non-manifold edges, and prong clearance, making it a solid starting point for jewelers, casting houses, and CAD-to-wax service providers. Because components are separated logically (bow, basket, post assembly), manufacturers can easily adjust post length, swap clutch styles, or rescale the gem seat without reworking the entire file. The design is compatible with standard 4mm round stones out of the box and can be adapted for lab-grown or natural diamonds, moissanite, cubic zirconia, or other round gemstones of similar dimensions.
Sales & Licensing Use
This CAD file is ideal for sale on 3D model marketplaces, jewelry design platforms, and print-on-demand manufacturing services catering to independent jewelers, small studios, and hobbyist designers. Buyers can expect a ready-to-print package (STL, OBJ, and native 3DM formats, with additional formats available on request) suited for prototyping, sampling, or direct production runs. The listing is well suited to buyers searching for stud earring designs, bow-themed jewelry, minimalist diamond earrings, or gift-ready earring CAD files, and its multi-metal rendering makes it easy to showcase versatility to potential retail customers or private clients before committing to a specific finish.
