The 18kt White Gold Black & White Diamond 3-Ring Combination by Verifine London. The effect of a black diamond eternity ring in 18kt white gold, sandwiched between 2 sparkling diamond eternity rings also in 18kt white gold is startling. Over 80 white diamonds and 40 black diamonds are micro-set into these 3 stacking rings. This stunning handmade piece of designer jewellery is suitable for any occasion and outfit. About The Designer: When husband and wife team Neil and Wendy Duckworth established Verifine they had a clear objective in mind: to craft gorgeous, skinny eternity rings that sparkled enough to stand alone, yet could be easily stacked. From there, this London business has grown to include earrings, bracelets and necklaces as well as their iconic slender bands set with luminous precious stones.
