A diamond eternity band in 14K gold that is 1.70 mm wide is a slightly wider version of the 1.40 mm band, offering a bolder and more substantial look while still maintaining its elegance and sophistication. The 14K gold is a durable and popular choice for jewelry, and the wider band allows for more diamonds to be set into the ring, providing more sparkle and shine.

The wider width of the band also means that the diamonds will be set a bit further apart, which can make them stand out even more.

This ring is an eternity band, meaning the diamonds are set all the way around the band. This symbolizes everlasting love, making it a popular choice for engagement and wedding rings, as well as for anniversary or special occasion gifts.

Overall, a diamond eternity band in 14K gold that is 1.70 mm wide is a beautiful and classic piece of jewelry that is perfect for adding sparkle and elegance to any outfit.
