A tennis necklace takes the same continuous-line idea as a tennis bracelet and carries it around the neckline: a flexible row of diamonds designed to follow the curve of the neck rather than sit stiff.
Carat weight is what really separates the pieces in this collection. They range from 5 carats to 37.50 carats total weight — far beyond our tennis bracelets, which top out at 9 carats. At the lower end, the necklace reads as a fine line of light. At the top end, it becomes the piece people notice first.
Every necklace here is made in 14K gold, with twenty-one in white gold and eleven in yellow gold, and every one is set with lab grown diamonds. That is a big reason these higher total carat weights are available at these prices — matching twenty or thirty carats of natural diamonds into a single line would put the cost in a very different range.
Nearly all are F color with VS clarity, and the collection uses round brilliant diamonds throughout.
Most of the collection is 17 inches, a classic tennis-necklace length that sits close to the base of the neck on many people. There are also three 18-inch options and one 22.6-inch piece for a longer drop.
If you want to understand the difference between the two diamond origins, our guide to lab grown vs. natural diamonds explains how they compare in appearance and price.
Looking for something you don’t see here? Email Info@monetaryjewelers.com with the carat weight, metal, length and diamond origin you have in mind. We regularly work with custom orders, including natural diamond versions and lengths outside the options listed here.
Prices range from $7,560 to $37,800, and every necklace in the collection qualifies for MJC Card financing based on the current $1,500 minimum purchase requirement. There is no hard credit inquiry required to apply, though approval is not guaranteed.
