~BOYSENBERRY~ vintage tanzanite x diamond ring

Very high quality vintage 18k yellow and white gold ring. Featuring a spectacular 6 x 5 mm cushion cut deep royal blue tanzanite with excellent lustre and fire. Flawless cut! In artificial light, the stone presents a more violet hue as is the nature of tanzanites (trichroism). About a carat, estimated whilst set. 
Set with trapeze baguette diamonds about 4 mm in length. 4 grams ring weight. 
The ring is handmade, and it is about a size 8 . All stones earth mined, tanzanite might have plain heat. There’s a very slight corner facet abrasion I caught on the video, which I can’t see in the magnified photos and definitely not with the naked eye. But I’ve put a screenshot photo of it anyway. 
As usual with my vintage and antique offerings, this is NOT a price point I could offer if I was to make this ring new and handmade. So once it’s gone, it’s gone.
Resizable at cost but not until 12/01/2026
