Lab-Grown Diamond Influencer Collaboration Programme
Love creating jewellery, fashion or lifestyle content? Partner with MadisonDia and style real IGI-certified lab-grown diamonds — sponsored pieces you keep, a personal code for your followers, and commission on every sale you inspire.
MadisonDia is the lab-grown diamond brand of Madison Avenue, a Hong Kong luxury retailer that has been an authorised dealer for Versace, Hugo Boss and Moschino since 2012. Our creators have already introduced MadisonDia to audiences across Asia — see who we work with on our partnered artists and KOLs page.
What You Receive as a MadisonDia Influencer Partner
Lab-grown diamond pieces to keep
From a pair of 1ct diamond earrings up to a 2ct diamond ring, chosen to suit your style. No need to return them after the collaboration.
A personal discount code
Your followers get their own code to use on madisondia.com. The discount is set for each partnership rather than one fixed rate for everyone.
Commission on every referred sale
Earn a percentage commission on each purchase made through your link or code. Rates are agreed individually, based on your platform, audience and content format.
Your own signature design
Selected partners can go further and launch a co-branded ring or pendant through our KOL co-branding programme.
Who We Are Looking For: Jewellery, Fashion & Lifestyle Creators
You don't need to be a diamond expert — we'll explain everything about colour, clarity and cut so you can share it with your audience in your own words. What matters most to us:
- Content in jewellery, fashion, beauty, bridal, travel or everyday lifestyle
- Active on Instagram, TikTok, Threads, YouTube, Xiaohongshu or a similar platform
- A highly engaged audience — there is no minimum follower count
- A natural, honest way of showing products in daily life
No minimum follower count. We look closely at engagement. For example, an account with 20,000 followers and a 4.5% engagement rate is a great fit for us.
