  • Tiffany & Co. Ruby Tri-stone Ring, Trilliant Diamonds

    As you know, T&Co. hasn't been routinely carrying rubies for a LONG time. Here's your chance to snatch up a rare ruby ring, complete with original paperwork from the year 2000! Center stone is 0.60 carat, with 0.19 TW trilliant diamonds flanking it. Way back in 2000, it was valued at $4350 so it would easily be double that now, plus the rarity value. FYI, the ruby band ring pictured in one of the photos is NOT included in this listing, but I'll be listing that soon as well. Happy bidding!
