NWT VERY RARE Volcanic Quartz (Rare) sterling size 7

NWT VERY RARE Volcanic Quartz set in Platinum over sterling 925 marked see photo, size 7, total ctw 11.5. Rare stone surrounded by 6 larger zircon and the center mounting is also surrounded by smaller Zircon stones. One of the prettiest rings in my collection. Stone is on the larger size but not gaudy. Has hues of deep pink, blue, purple and red, just an all around beautiful ring. Please don’t lowball priced well below retail.
