Wedding day jewelry is about so much more than accessorizing—it’s about finding a unique piece with the potential to become a family heirloom. There is perhaps no wedding necklace style more fitting for the title of an heirloom than the tennis necklace. Dubbed after the iconic bracelet style with the same moniker, the tennis bracelet makes a statement and is the perfect piece to accompany the most important aspect of a wedding wardrobe: The dress. 

Tennis necklaces have long been a staple in wedding day accessories and a favorite amongst celebrity nuptials (Paris Hilton recently wore a stunning tennis necklace with one of her bridal looks), making them a timeless wedding trend. “The Tennis necklace is a classic staple and signature piece,” says expert Kathryn Money. “Whether it’s a family heirloom or a gift to self, tennis necklaces are a jewelry wardrobe staple, perfect for everyday wear and occasions [such as your big day],” she adds.

The only downside to tennis necklaces is, because of the number of diamonds required for the design, they can be expensive. But, there are ways around the skyrocketing price tags with lab-grown diamonds. Because these diamonds are sourced from a lab and touchless hands through their creation, lab-grown diamonds tend to be more affordable compared to Earth-mined diamonds. Additionally, without the mining aspect, they’re more eco-friendly, too.

What to Look for When Shopping for a Lab-Grown Diamond Tennis Necklace 

Color Grade and Cut  

“Although the clarity of the diamonds in a tennis necklace is important, the color grade and cut quality are more important to get a dazzling necklace,” says Money. “As each diamond is small in size and carat weight, it will not be easy to tell the difference between an internally flawless diamond without expert training and equipment,” she adds. Money recommends getting a necklace that is considered “eye clean” which means “any blemishes or imperfections affecting the clarity will not be noticeable to the naked eye.” Doing so “can help when working with a budget and without affecting the visible beauty of the necklace.”

Metal

“The color of the metal is the most important regarding design,” says Money. “Yellow gold options are unique and non-traditional diamond necklaces,” she adds, noting how yellow gold compliments warm skin tones while “rose gold goes well with any skin tone.” As far as a necklace for everyday wear, “platinum is ideal,” says Money. “Platinum offers more strength and is perfect for someone who wants to wear their necklace every day without worrying about it breaking,” she adds, noting how the trade-off is that platinum “is much more expensive than gold.” For the best of both worlds, Money recommends white gold as it offers a “mix of metal durability and price.” White gold is “more durable than yellow gold but not as expensive as platinum.”

FAQ
  • What Are Tennis Necklaces?

    “Similar to the well-known tennis bracelet, a tennis necklace refers to an uninterrupted diamond strand,” Money explains. “It looks like a tennis bracelet, but it’s longer and can encircle the neck,” she adds, noting how the style is “timeless” and considered a “statement piece.” 

  • What's the Difference between Lab-Grown vs. Natural Diamonds?

    Lab diamonds are “grown in highly controlled laboratory environments” and “display the same characteristics as natural diamonds,” says Money. The only real difference is their origin, as one is created in a lab and the other is made by Mother Earth. Lab diamonds “exhibit the same spark and scintillation as natural diamonds” and “are a great alternative to natural diamonds as they provide good value and a responsible choice, given they do not require any diamond mining,” Money adds. 

  • Can You Wear Tennis Necklaces with a Wedding Dress?

    As far as wearing a tennis necklace with a wedding dress goes, Money says you “absolutely” can. “The versatility of the smaller diamonds found within tennis necklaces provides wearers with various styling options,” she adds, noting how a wedding necklace is all about something that is lasting with personal meaning, making it “the perfect wedding day accessory” with its “timeless style that can even be worn often and effortlessly beyond the wedding day.”
