## What BrillPulse is (RU)

BrillPulse — закрытая аналитическая площадка команды аналитиков.
В первую очередь мы анализируем рынок бриллиантов (не алмазов как основной объект).
Мы делаем это по собственной инициативе, без платных продуктов и без попытки получить выгоду.
Цель — дать участникам рынка бриллиантов ещё одно независимое мнение,
которое может быть полезно для их собственных выводов.

Мы предоставляем независимый анализ: только факты с данными, на которых строятся выводы.
Мы не продаём доступ и ничего не рекламируем. Доступ выдаём по запросу.
Запрос на регистрацию аккаунта: info@brillpulse.com
Мы не оцениваем камни и не обещаем доходность. Факты констатируем, анализируем;
сценарии помечаем отдельно — итоговые выводы участник делает сам.

Мы агрегируем информацию:
- новости рынка бриллиантов из доступных источников (алмазы — смежный контекст);
- открытые индексы и собственные индексы;
- инструменты сравнения камня с похожими позициями;
- инсайты, подкреплённые надёжными данными.

## What we do

- Aggregate polished-diamond / brilliant market news from available sources
- Aggregate open market indices and build our own indices
- Provide tools to compare a stone with similar positions
- Share insights backed by reliable data
- State facts; leave interpretation and decisions to the participant

## What we do NOT do

- Sell access, subscriptions, or any paid products
- Advertise goods or services
- Seek commercial benefit from this work
- Issue stone appraisals / valuations or promised investment returns
- Present unlabeled guesses as hard facts (scenarios must be marked)
- Treat the rough-diamond market as our primary focus
- Publish a public open dataset or open news portal
- Replace the participant's own judgment
