70 Carat White Topaz Necklace Sterling Silver
Vintage sterling Silver chain necklace with pendant. The pendant is set with a huge oval faceted white topaz stone. I was told that it was rock crystal when I purchased it, but it has more of a metallic diamond flash so I tested it and it's topaz. I used a calculator to determine carat weight and it comes in the range of 66 carats to 77 carats. It has a very deep and full pavilion so I would say it is on the higher end of the scale.
Because the pavilion is so deep it does not lay super flat on your chest. A bit of cleavage helps the matter. See photos of it being modeled.
It measures 1 3/8" long by 1 1/8" wide. The chain is 20" long. Necklace weighs 31 grams and most of that is rock.
It has tremendous sparkle and shine. Very impressive piece! Very clean stone that you can almost read a book through.
