Small Orange Diamond Emoji

The small orange diamond. Ninety-nine percent of the time, this emoji is a sub-bullet: the quieter sibling of 🔶 that handles detail items, secondary points, and Instagram-bio separators. Its job is to be small enough to not dominate the line, so the content stays the focus. Where 🔶 headlines the section, 🔸 carries the fine print. The other one percent of the time, 🔸 is a political-adjacent badge. Giving What We Can, the effective-altruism-linked charity, officially asks people who've taken their 10% Pledge to add 🔸 to their display names on X, LinkedIn, and Bluesky. Since the campaign launched in July 2024 the small orange diamond has become an increasingly visible marker across tech-adjacent and EA-adjacent corners of social media. Approved in Unicode 6.0 (October 2010).

Instagram bios are 🔸's biggest ecosystem. "NYC 🔸 Photographer 🔸 DM for collabs" is the canonical format. The character is compact enough to work as a separator between short phrases without clutter, and it respects Instagram's 150-character bio limit (every pixel counts). On LinkedIn and Twitter/X threads, it pairs with 🔶 as the sub-bullet under a main section header. On TikTok, it's a common caption separator for video descriptions that pack hashtags, credits, and a CTA into a single line.

The EA / 10% Pledge usage is smaller in volume but distinctive. If you scroll EA Forum, Bluesky's tech-policy crowd, or the quote-tweet replies under a Giving What We Can post, you'll see display names like "Jane Doe 🔸" where the diamond is signaling "I've pledged to donate 10% of my income for life." Some pledgers use it everywhere; others (like Jeff Kaufman) only use it in EA-adjacent spaces where the context makes the signal legible.

🔸 is half of a matched pair with 🔶, both inherited from Japanese carrier emoji sets of the late 1990s and early 2000s. SoftBank, au, and DoCoMo included small and large versions of each colored diamond so users could build structured lists and decorative text-art in a world before rich text. When Unicode standardized these in version 6.0 in October 2010, they were codified at U+1F538 (small) and U+1F536 (large) with the colors frozen as canonical.

The 10% Pledge repurposing is a much newer story. Giving What We Can, founded in 2009 by philosopher Toby Ord and economist Will MacAskill at Oxford, asks members to commit publicly to giving at least 10% of their income to high-impact charities for life. In July 2024 they formally rebranded the commitment as the "🔸10% Pledge" and asked pledgers to add the small orange diamond to their display names. They chose orange over blue because it matched their existing brand palette; the small size was chosen over the large so it wouldn't dominate a username. The goal is pure curiosity-marketing: seeing several 🔸s in your feed makes you eventually ask "what does that mean?" and click through to learn.

• •🔸 is the official badge of the 10% Pledge, Giving What We Can's public commitment to donate 10% of income to high-impact charities. Over 10,000 people worldwide have taken it.
• •The 10% Pledge was renamed from "the Giving What We Can Pledge" in July 2024 precisely to make it more legible: the new name includes a number and an emoji, both more shareable than abstract wording.
• •Giving What We Can chose orange over blue for the pledge badge because it matched their existing logo palette. Blue diamond emojis already carry other associations (LinkedIn formality, Ethereum, verification).
• •Instagram bios are capped at 150 characters, which is why compact separator emojis like 🔸 became so popular. Every saved character is more room for a tagline or emoji.
• •Jeff Kaufman's Signaling with Small Orange Diamonds post on the EA Forum in November 2024 sparked an ongoing debate about the etiquette of visible charitable signaling online.
• •The small-large pair of geometric diamonds (🔸🔶 and 🔹🔷) was deliberately designed by Japanese carriers as a matched size system, so users could build visual hierarchy in plain-text emails before HTML was standard on mobile.
