Piece of the Week: Jemma Wynne’s Trillion Tubogas
The statement piece is perfect for a bold holiday look.
Move over, neck mess.
Jemma Wynne makes the case for a single, center-of-attention statement piece with its new tubogas collar, National Jeweler’s “Piece of the Week” this week.
There’s no need to pile on a mountain of necklaces with a jewel this dramatic.
Rather, the company’s latest creation is the kind of accessory one chooses first for an elegant soiree, crafting their entire ensemble around it.
An elegant suit’s plunging neckline or an off-the-shoulder gown’s bare shoulder canvas would make the perfect backdrop for the tubogas at a dressed-up holiday affair.
The 18-karat gold tubogas—or hollow necklace in which gold strips have been wrapped together to form a chain—is adorned with an 18-karat gold medallion pendant featuring a 1.5-carat D-color trillion-cut diamond set in a diamond halo with rhodium detailing.
Diamonds and rhodium also adorn the bale.
Priced at $50,500, the one-of-a-kind jewel is available through the Jemma Wynne website.
