18k Tri-Tone Gold Serpent Bypass Coil Ring

This is a contemporary bypass-style coil ring crafted in 18k multicolored gold. The design features a continuous band that wraps around the finger approximately three times, emulating a serpent or spiral motif. Each coil end is accented with a different metallic finish—white gold and rose gold—contrasting against a primary yellow gold shank. The white gold and rose gold tips appear to be set with small round brilliant-cut diamond melee, though the exact carat weight is undetermined without measurement. These accents are secured with small prongs or beads in a pave-style setting. The shank has a high-polish finish and a rounded comfort-fit interior. Given the 18k hallmark mentioned, the metal is a high-purity alloy suitable for fine jewelry. Observations of the condition show minor surface abrasions and micro-scratches consistent with light wear. The polish remains bright, and there are no visible signs of structural deformation or missing stones. The craftsmanship suggests a modern production, likely from the late 20th or early 21st century. The tri-tone aesthetic allows for versatility in pairing with other jewelry pieces.

Based on my visual examination of the provided images, this is a striking contemporary bypass coil ring executed in 18k tri-tone gold. The hallmark, as reported, indicates a high gold purity of 750 (18 karat), which serves as the primary driver of value. The design features a serpentine or tubogas-inspired spiral that wraps the finger three times, terminating in contrasting white and rose gold caps accented with what appears to be pavé-set diamond melee. The total weight of the piece is a critical unknown factor, but the multi-coil construction suggests a substantial gold weight, likely between 8 to 12 grams. The condition appears to be 'Very Good,' showing only minor surface abrasions consistent with light, occasional wear. The polish remains high, and the structural integrity of the bypass mechanism seems sound. Market demand for tri-tone gold remains steady due to its versatility, and the serpent motif is a perennial favorite in jewelry history, popularized by houses like Bulgari, though this piece appears to be an unbranded or private label contemporary design. Valuation is based on the current gold spot price for 18k scrap, plus a significant premium for craftsmanship and retail markup typical for fine fashion jewelry. Comparable unbranded 18k Italian-style coil rings generally retail in the secondary market between $1,400 and $1,800, depending heavily on the total gram weight and diamond quality. Limitations: My appraisal is strictly based on the provided imagery. I cannot confirm the specific carat weight or grading (color/clarity) of the accent stones, nor can I verify if they are natural diamonds without thermal testing. An in-person inspection is required to weigh the item, test the specific gold alloy, and examine the maker's mark to rule out or confirm a designer attribution.
