A rare 10.51 carats Ruby* sells for more than 18 times its presale estimation (estimated by Chiswick Auctions) at auction.

Rubies are found throughout the world from Australia to Africa, but the most famous and prized stones come from the remote ruby mines in Mogok, Upper Burma (Myanmar). This small area of only a few square miles is known as the “Valley of Rubies,” and has produced some of the most beautiful gemstones in the world, like that one.

To be clear with you since the beginning, I am not very convinced that traditional jewelry estimations are done properly today. A so-big-difference between the sold price and the initial price is a big deal. An “amazing result” that was announced by the Auction House is alarming. In this little first episode, Stephane Boghossian, our jewelry expert, will explain to you why he shares this value.

The beautiful jewel [by Chiswick auctions]

The ring, from a private European estate, sold for £462,500 (incl. BP), which is more than 18 times its pre-sale low estimate of £25,000. The impressive ruby is accompanied by two gemological reports that confirmed it was natural and unheated.

Estimations today

Today, estimations are still done manually by an appraiser. Every appraiser has its own strategy (it can vary from one jeweler to another) but most models involve calculating the precious materials’ market price. Appraisals can cost 30% of your jewelry and can take up to 7 days to be done properly (make the equation for that Ruby and you’ll see that it is quite a lot). If not done professionally, appraisers are generally a very complicated piece of paper with numbers you don’t even understand.

DATA is gold

At ExJewel, we value the power of data. Data is gold as we might often say. ExJewel’s robot fetches qualitative and quantitative data from 20+ sources, from mining companies to big online suppliers. Yes, I forgot that some of you don’t know what a robot-algorithm is. Well, a robot is a thousand faster human that scraps data from all re-commerces* and marketplaces to analyze them and regroup them into a smart filing system. 

Re-commerce is an online marketplace for second-hand products, in our case, jewelry.

Conclusion 1: The result is just brilliant

Exjewel’s estimation has an equation structure that contains information that predicted the price of that Ruby days before the auction happened. Anyway, all this is to say that we calculate the incalculable and we are pretty good in data analysis but the real problem we are solving is: Bring transparency to both customers and supply chain actors including Auction Houses, established or independent.
