JewelAna

The story

Valuing jewellery from a photograph sounds like a party trick and is a daily chore. A jeweller estimating a piece has to judge the metal, the weight, the stones and today's gold rate, and do it quickly enough that the customer standing in front of them does not go elsewhere.

JewelAna does the arithmetic: it reads the piece from the photo, estimates what it is made of, and applies the live gold price to produce a number in rupees that a jeweller can defend.

It is in pilot in the truest sense — one jeweller is putting real pieces through it, and what we want out of that is the list of things it gets wrong. No number goes on this page until their trial has an answer.
