Internally Flawless crystals occur infrequently and the market-reality is they are actually unusual. VVS is where most ‘clean’ gems fall on the clarity scale, and VS can be thought of as ‘eye clean at jewelry viewing distance (30cm+)’. With SI and I becoming included. Pls read the Clarity page for more info.
Our gemstones are vetted during purchasing by highly experienced gemologists, and then formally tested in our own lab. Many of our gems are also awarded reports by independent gem labs — making a triplicate of gemological security.
Ethics & Standards
We support ethically purchased gemstones from artisanal miners, small businesses and local communities. We avoid gems connected to environmental degradation and human rights abuses, and we try to use recycled gold whenever we can.
Our gems come in high-quality paper gem-wraps¹, or protective display boxes². We do not use any single-use plastics at all that are bad for the environment. Sturdy, secure recycled thick-paper mailing envelopes ensure everything arrives in perfect condition.
