Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.

ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 14 of 20 measured posts that carry a reaction reading, and over those same posts' views.

Readings taken15 Aug 2026, 08:45 UTC

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.

Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.

Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Lifetime counters from Telegram’s own channel header, read 15 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Measured directly from 1 video with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no mark.

Reaction mix

60 reactions across 14 posts, in 4 distinct kinds. The most used accounts for 51.7% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 14 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 60reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 12 August 2026 to 14 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

سبک تراش برلیان به سبکی گفته میشود که در آن فست ها به شکلی تراش داده میشوند که با بکدیگر و یا با گیردل زاویه تند داشته باشند. تامام تامام😇 هر چی تا بحال یاد گرفتید دور بریزید. مفهوم خیلی ساده است. دلیل این سبک تراش آن است که نور وارد شده به سنگ شکسته شده و در داخل سنگ به دام بیوفتد. نتیجه این مسئله درخشش (برلیانسی) بسیار بالای سنگ می باشد.

خب سوال بعدی این است که سبک تراش برلیان به چه سبکی گفته میشود؟😇😉

اما برویم سراغ سبک تراش: دو سبک کلی وجود دارد: فست و دامله یا کبوشن که موضوع بحث ما تراش فست است چون تراش دامله بسیار ساده است و نیازی به توضیح خاصی ندارد. تراش فست سه سبک دارد: تراش برلیان، تراش پلکانی (استپ کات که امرالدکات یا تراش زمردی هم گفته میشود) و تراشی که ترکیب این دو است که به آن میکسد کات گفته میشود.

در این عکس شکل گرد را درست نوشته. پس میبینید که این یک معضل است و باید از پایه مطالب را درست یاد بگیریم.

جالب است در همین عکس هم که از اینترنت گرفتم اشتباه وجود دارد. شکل ردیف اول سمت راست شکل گرد (round) را برلیان گذاشته که خوب همین مسئله ای است که ما سعی میکنیم آن را شفاف کنیم.

مثلا این تعدادی از شکلهای تراش است که در همه گوهرسنگها قابل اجراست

خب برویم سراغ ادامه بحث: تا اینجا گفتیم که در بحث گوهرها، باید بین شکل و سبک تراش تفاوت قائل شویم. در اینجا مثالهایمان بیشتر برای الماس است اما فرقی نمی کند هر تراشی که الماس میخورد برای سایر گوهرسنگها هم قابل انجام است. مثلا سبک تراش برلیان یا استپ کات هم می تواند روی الماس ایجاد شود و هم مثلا روی کوارتز یا آپاتیت یا حتی زمرد. همین مسئله در مورد شکل هم صادق است.

سپاس از سه بزرگواری که پاسخ دادند. آیا در پرسش صحبتی از شکل تراش شد؟ یا فقط خواستیم که سبک تراش را بگویید؟

سبک سوم تراش که ترکیبی از دو سبک قبلی است تحت عنوان Mixed Cut شناخته میشود.

Showing the 12 most recent of 20 posts we hold for @geminstiran. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
