Men's 18k gold-filled double Miami Cuban link necklace,10mm thick, and 24 inches long. This set includes an  8.6 inch long bracelet. The set has been plated with 8 layers of polished 18k gold, has lobster claw clasps, and the base metal is bronze.

Gold-filled jewelry has up to 100x more gold alloy than gold plated and because that layer is so much thicker, it means gold-filled jewelry lasts longer and stands up to wear and tear better than gold plated. All it would take is one small scratch on a gold-plated piece to expose the jeweler's metal underneath.

Gold filled pieces tend to be on the higher end of the cost spectrum while gold plated jewelry is more affordable as it only has a thin layer of gold to deliver the “appearance of gold.” That's the reason why most fashion jewelry pieces are gold plated—they can be priced lower and appeal to a broader customer base.

Such a substantial set as this in solid 18k gold would be cost prohibitive to the everyday person with the price of pure gold being $1937.75 ( /- $5.06) per ounce. A major, well known mall denizen is asking over $5500 on sale for their 20 inch byzantine 14 karat gold necklace alone.
