Black diamond minus white X (❖) is Unicode U+2756 in the Dingbats block. It is a filled diamond with a white X cutout — often used as a decorative marker or divider. HTML has no standard named entity — use numeric or CSS forms (or type the character in UTF-8).
Remember
Character ❖
Unicode U+2756
Hex entity ❖
Decimal ❖
Named entity (none)
CSS escape \2756
Not the same ♦ U+2666 (black diamond suit)
All of these produce the same glyph: ❖. Prefer typing ❖ in UTF-8 when you can; use ❖ / ❖ or CSS for generated content.
One page that shows ❖ with hex, decimal, CSS escape, and a typed character. Use View Output or open the live editor.
Hex + Decimal + CSS + Typed
Four ways to produce ❖ in a single document (no named entity).

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<style>
#point::after {
content: "\2756";
}

How It Works
1. Hex:U+2756 → ❖ in HTML. The browser turns it into ❖.
2. Decimal: same code point as 10070 → ❖. Same result as hex.
3. CSS: use \2756 in content (not an HTML entity). #point::after appends that ❖ after the paragraph text.
4. Typed ❖: fine in UTF-8 source. All four lines show the same glyph.

Describe decorative marks
Screen readers may skip dingbats. Hide pure decoration with aria-hidden, or add a short label when it carries meaning.
Fonts
Check Dingbats coverage
Some UI fonts omit U+2756. Prefer fonts with solid Dingbats / symbol support.
CSS vs HTML
Do not mix escapes
\2756 belongs in CSS. ❖ / ❖ belong in HTML.
Semicolon
End references
Always finish with ; — write ❖, not ❖.
