Quick answer
A fake panther ring 27mm is a replica of a Cartier Panthère de Cartier ring. The 27mm figure describes the panther head width across the top of the band. Cartier product pages do not list a 27mm head width, so the number comes from seller listings. Some sellers use 27mm for the inner diameter of the band instead. Ask which measurement applies before you buy.
Imitation Panther Ring 27mm: Sizing, Materials, and Buying Guide
What 27mm measures
27mm equals 1.06 inches. The band of a normal ring runs 2mm to 4mm wide. A 27mm head covers most of the finger from the base of the nail to the second joint. A 27mm inner diameter equals about US size 19, above the range most jewelers stock.
Head width and ring size are two numbers. A panther head in this size sits on bands from US 5 to US 10.
Metals in replicas
- 316L stainless steel with gold PVD plating. Plating runs 0.3 to 1 micron. Daily wear breaks the plating in 6 to 18 months.
- Brass with gold plating. Heavier than steel. Tarnishes at the edges and inside the band.
- 925 sterling silver with a gold or rhodium wash. Silver content shows on an XRF scan.
- Tungsten carbide. Uncommon in panther copies because the head detail is hard to cast.
Genuine Panthère rings use 18k gold, stamped 750, with onyx or black lacquer spots. Some models add tsavorite garnet eyes and diamonds.

Checks on a ring in hand
- Read the inside of the band. Real pieces carry a 750 stamp, a maker's mark, and a serial number.
- Weigh the ring. An 18k gold panther ring in this head size runs 12 to 20 grams. A plated steel copy runs 6 to 10 grams.
- Look at the spots. Onyx is stone and feels cool on the skin. Painted enamel chips at the edge.
- Hold a magnet to it. Gold and sterling silver do not stick. Steel and nickel alloys do.

Legal note for US buyers
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. Prosecutors charge sellers, not buyers, in most cases. U.S. Customs and Border Protection can seize and destroy counterfeit jewelry at the border. The FTC requires accurate stamps on precious metal content for jewelry sold in the US.
