Jewelry Affiliate Program | Earn Commission on Diamonds
The MadisonDia Jewelry Affiliate Program is open to creators based in USA, Australia, Japan and Hong Kong. If you have 15,000 or more Instagram followers and an engagement rate of at least 2.0%, you can earn up to 15% commission on every order your audience places — with higher tiers unlocking as your referred sales grow. Every approved partner also receives a complimentary pair of 1-carat total (0.5 ct each) lab-grown diamond stud earrings.
How the Jewelry Affiliate Program Works
Affiliate marketing is a performance-based partnership. You receive a personal referral link and a discount code. When someone from your audience uses either one to place an order, you earn a commission on the sale. Unlike a flat sponsored-post fee, affiliate income compounds over time — every piece of content you publish keeps working long after it goes live, and creators with highly engaged communities of even a few tens of thousands of followers can generate meaningful, recurring revenue.
MadisonDia is a Hong Kong-based lab-grown diamond jewellery brand. Our parent company, Madison Avenue, has been an authorised dealer for Versace, Hugo Boss and Moschino since 2012. The brand holds Hong Kong Government "No Fakes" certification and a Precious Metals & Stones Dealer licence (Cat. A, Reg. No. A-B-26-05-10954). On BUYMA, we maintain a 5.0 rating with over 1,343 verified reviews. When you recommend MadisonDia, you are recommending a brand with a physical store, government registration and over a decade of luxury retail heritage.

Jewelry Affiliate Requirements — Who Can Apply
We do not make decisions based on numbers alone, but the following benchmarks serve as a useful reference before you apply. If you fall short on one or two metrics but produce high-quality content with a strong relationship with your audience, we are happy to discuss your application individually.
| Metric | Benchmark | Notes |
|---|---|---|
| Follower count | 15,000+ on Instagram | Creators active primarily on YouTube, TikTok or blogs are welcome to enquire |
| Engagement rate | 2.0% or above (Japan) 2.5% or above (Hong Kong) |
Average of last 12 organic posts; ad posts excluded |
| Reels views | 30% or more of follower count | Average of last 3 Reels |
| Story reach | 8% or more of follower count | Used to assess link-sticker effectiveness |
| Audience location | 60%+ based in Japan or Hong Kong | Instagram Insights screenshot required |
| Account age | 6 months or more with consistent posting | Approximately 4 posts per month |
| Content niche | No restrictions | Jewellery, fashion, lifestyle, bridal, beauty, travel, food, parenting, fitness, art, entertainment and all other niches are welcome. Creators focusing on weddings and anniversaries are especially encouraged |
How We Calculate Engagement Rate
We use the following formula for this programme:
Engagement rate (%) = (likes + comments + saves + shares) ÷ followers × 100
Saves and shares are included because jewellery is a high-consideration purchase. A follower who saves a post to revisit later is much closer to buying than one who simply double-taps. If we measured likes alone, accounts with strong purchase intent would be undervalued.
For reference, accounts in the 10,000–50,000 follower range typically see engagement rates between 1.5% and 3.5%. Japanese accounts tend to score lower than global averages at the same follower count, which is why we set the Japan benchmark at 2.0% and Hong Kong at 2.5%. If your engagement rate exceeds 3.5%, contact us to discuss starting at a higher commission tier.
Jewelry Affiliate Commission — Up to 15% Per Sale
Your commission rate increases automatically as your cumulative referred sales grow. Once a tier is reached, it never drops back down.
| Tier | Cumulative referred sales | Commission |
|---|---|---|
| Starter | Up to USD $12,500 | 10% |
| Signature | USD $12,500 – $38,000 | 12% |
| Atelier | USD $38,000+ | 15% |
A personal code your followers can use at checkout. Commission is calculated on the discounted amount.
Any order placed within 30 days of a link click counts. Orders placed with your discount code are attributed regardless of timing.
Unpaid amounts roll over to the following month.
Loose diamonds, rings, earrings, pendants and custom orders are all included.
When Commission Is Confirmed and Paid
Commission is confirmed once the return window for an order has closed. Loose diamonds carry a 30-day unconditional return period, while finished jewellery has a 14-day conditional return with one year of complimentary repair — so confirmation takes a little longer than a typical affiliate programme. Confirmed commission is paid by bank transfer at the end of the following month. Transfer fees are covered by MadisonDia.
Returns and cancellations: returned orders are deducted from unpaid commission. Commission that has already been paid out will never be clawed back.
Affiliate Welcome Gift — 1 Carat Diamond Earrings
Once your contract is signed, we send you a pair of lab-grown diamond stud earrings totalling 1 carat (0.5 ct per ear). They are yours to keep regardless of whether you generate any sales.
0.5 ct per ear — the sweet spot for on-camera visibility and everyday wearability.
Top of the colourless range. Visually indistinguishable from D in a finished earring setting.
Negligible inclusions, visible only under 10x magnification by a trained grader.
Your choice of yellow, white or rose gold. Built for daily wear and content shoots alike.
Maximum fire and scintillation — the most photogenic cut for earring studs.
Each stone is inspected and confirmed as D–F colour, VS–VVS clarity by MadisonDia's team. No IGI certificate — IGI is issued for centre stones 1 ct and above only.
No clawback, no return requirement, no minimum sales target. The earrings are a gift, not a loan.
Publish 3 posts within 60 days of signing. HK shipping free; Japan import duty covered by MadisonDia.
How to Promote Jewelry as an Affiliate — Content Ideas
"How should I actually promote this?" is the question we hear most. Below are the content formats that consistently perform well. You do not need to try every one — pick two or three that fit your style and audience.
Three shots: opening the box, holding the piece up to light, wearing it. Slow hand movements let the viewer see how the diamond plays with light.
Every centre stone 1 ct+ ships with an IGI certificate. Teach your audience how to read it — saves run 3–5x higher than average posts.
1 ct from $250, 1.5 ct from $417, 2 ct from $617. Frame these against natural diamond prices and your own budget — the gap does the talking.
"Are lab-grown diamonds real?" Collect questions via Story stickers and answer them. Lowest production cost, highest direct impact on sales.
Proposal and Anniversary Stories
Content tied to your own experience or a partner's real moment creates the closest connection with your audience. Reference our Engagement Ring Buying Guide to walk through ring sizing and design decisions. Posts that document the process tend to generate the highest link-click rates.
Styling and Stacking Suggestions
Seasonal outfit pairings — earrings, pendant and ring combinations — are easy to serialise and keep your referral links active over months rather than a single campaign window.
IGI Certificate Deep-Dive
Our Lab-Grown Diamond Certification Guide breaks down every field on an IGI report. Put it in your own words and walk your audience through colour, clarity and cut grades. This format builds trust because you are teaching, not selling — and educated followers convert at a much higher rate.
Why Affiliates Choose This Jewelry Program
Diamond jewellery commands a higher average order value than fashion or beauty, which means each commission payment is larger even at the same percentage.
Physical store in Tsim Sha Tsui, government licensing, 1,343+ verified reviews. Your audience can verify everything independently.
Engagements, anniversaries and birthdays happen year-round. Diamond content does not go seasonal the way fashion does.
Free earrings, no minimum sales, no clawback. If the partnership does not work out, you keep the gift and walk away.
Jewelry Affiliate Disclosure Rules — Japan & Hong Kong
Transparency builds trust — and in both Japan and Hong Kong, it is also a legal requirement. All affiliate partners must comply with the following:
- Include "Ad", "Sponsored" or "Provided by MadisonDia" at the beginning of the post or visibly on the image
- A hashtag alone is not sufficient — the disclosure must be clearly legible in the caption or on screen
- For Reels, display the disclosure within the first 3 seconds, or in the first line of the caption
- Even if you have not yet earned any commission, disclosure is required whenever you have received a gifted product
- Japan-based partners: posts must comply with the Consumer Affairs Agency's designation on stealth marketing under the Act against Unjustifiable Premiums and Misleading Representations. See the CAA stealth-marketing guidelines
- Hong Kong-based partners: posts must comply with the Trade Descriptions Ordinance. See HK Customs — Trade Descriptions Ordinance
These rules protect you as much as they protect MadisonDia. If you are unsure how to format your disclosure, we will provide specific examples when you sign your agreement.

Jewelry Affiliate Program — Frequently Asked Questions
Can I apply if I have fewer than 15,000 followers?
If your engagement rate exceeds 4%, or if your account is focused specifically on bridal or jewellery content, we will consider your application on a case-by-case basis. Mention this when you email us.
I am based in Hong Kong but most of my audience is in Japan. Which benchmark applies?
We go by where your audience is located. If 60% or more of your followers are in Japan, the Japan benchmark (2.0%) applies and your commission will be paid in JPY.
Can I run other brand affiliates at the same time?
Yes. We only ask that you do not feature a competing diamond brand in the same post.
Does the welcome-gift earring pair come with an IGI certificate?
No. IGI certificates are issued for centre stones of 1 carat or above. Each earring stone is 0.5 ct — a melee size graded in-house by MadisonDia and confirmed as D–F colour, VS–VVS clarity before it ships.
How do I track my commission?
Your personal dashboard shows clicks, orders, pending commission and confirmed commission in real time. We also send a monthly summary by email.
What is the average order value for MadisonDia?
Most referred orders fall in the USD $250–$1,700 range, which means even at the 10% starter tier, a single referral can earn $25–$170. Higher-carat custom orders regularly exceed $2,000.
Can I visit the store to see the products in person?
Of course. Our shop is at G11, Hankow Centre, 5–15 Hankow Road, Tsim Sha Tsui, Hong Kong. We are open daily from 12:00 to 20:30 (closed Saturdays). G11 is on the ground floor of a shopping mall, not an office tower — walk-ins are always welcome, no appointment needed.
