The Opportunity

A $38B market with
no price benchmark.

Colored gemstones are a $38.4B market growing at 6.6% CAGR to $72.8B by 2036. Unlike diamonds, every colored stone is unique — there is no standardized pricing. Two identical-looking 3ct rubies can be $5K and $500K.

This single gap cascades: banks won't lend against colored gems (can't value collateral), insurers can't price risk (appraisers disagree by 300%), and miners sell at 10–20% of retail because they lack the pricing information to negotiate.

While natural diamond prices fell over 20% between 2022–2023 due to lab-grown disruption, top-tier colored gems — rubies, sapphires, Paraíba tourmalines — held and appreciated. They can't be synthesized at scale. Knight Frank reports 23% of ultra-high-net-worth individuals now hold them as alternative assets.

The infrastructure exists. The pricing layer doesn't. We're building it.
