BOJ Rewards is Beauty of Joseon's free gems program for shoppers on its US store. Members earn 1 gem for every $1 spent, plus gems for joining, subscribing to the newsletter, following BOJ on TikTok and Instagram, writing reviews, referring friends and their birthday. 80 gems convert to $5, so the base earn works out to a 6.25% return (our arithmetic). Gems can also be exchanged for 10%, 15% or 20% off, or for full-size skincare, and spending $300, $600 and $1,000 moves a member up through the Amber, Jade, Pearl and Sapphire tiers.

How to join BOJ Rewards
Joining starts with the "Join Now" button on the BOJ Rewards page, which is linked as "BOJ REWARDS" in the store's main menu. Members who already have an account use "Sign In". Gems are credited only from the moment a member joins, so orders placed before joining don't earn gems retroactively.
Every member starts in the Amber tier. Joining the program earns 50 gems, and joining the BOJ newsletter earns another 50.
How you earn gems
| Action | Gems | Notes |
|---|---|---|
| Place an order | 1 per $1 spent | Earned on every order |
| Join the program | 50 | Once |
| Join the BOJ newsletter | 50 | Once |
| Follow BOJ on TikTok | 25 | Once |
| Follow BOJ on Instagram | 25 | Once |
| Write a review | Up to 150 | BOJ doesn't publish what earns the top amount |
| Refer a friend | 150 | The friend gets 20% off |
| Birthday | 150 | Each year, and the FAQ says birthday gems rise as members move up the tiers |
The one-off actions are worth more than they look next to a 1 gem per $1 base. Joining, the newsletter and the two follows add up to 150 gems, which is $9.38 at the conversion rate (our arithmetic), the same as the gems from about $150 of purchases. A referral pays another 150 gems, and a member's birthday pays the same each year.
Higher tiers are described as unlocking "increased earning power". The only earn rate BOJ publishes is 1 gem per $1, and the tier table shows tier benefits as an upgrade bonus, early access and a gift rather than a faster earn rate.
What BOJ gems are worth
BOJ publishes the exchange rate on the redemption section: 80 gems equal $5. A gem is worth $0.0625, so the 1 gem per $1 earned on a purchase returns 6.25% (our arithmetic).
| Gems | What you get | Value at $0.0625 a gem |
|---|---|---|
| 80 | $5 off | $5.00 |
| 300 | 10% off | $18.75 |
| 500 | 15% off | $31.25 |
| 800 | 20% off | $50.00 |
| 400 | Free Revive Eye Cream 30ml | $25.00 |
| 600 | Free Glow Serum 60ml | $37.50 |
| 1,000 | Free Dynasty Cream 100ml | $62.50 |
The right-hand column is our arithmetic and is a way to compare the options, not a price BOJ gives. The percentage-off rewards depend on basket size: 20% off for 800 gems beats $50 only on an order above $250, assuming it applies to the whole order, which BOJ doesn't spell out.
How to redeem gems
Members choose from seven options in the "Redeem for Products" section: a percentage off at 300, 500 or 800 gems, a conversion of 80 gems into $5, or a free full-size product at 400, 600 or 1,000 gems. Free products are Revive Eye Cream 30ml, Glow Serum 60ml and Dynasty Cream 100ml.
Redeeming produces a code, and each order accepts only one redeemed code. A used code can't be reused or applied to another order.
Status tiers and perks
BOJ Rewards has four tiers named after gemstones. Reaching a tier needs spend of $300 for Jade, $600 for Pearl and $1,000 for Sapphire. Amber needs only a sign-up.
| Amber | Jade | Pearl | Sapphire | |
|---|---|---|---|---|
| Spend to reach | Sign up | $300 | $600 | $1,000 |
| Tier upgrade bonus | None | 100 gems | 200 gems | 300 gems |
| Early access to launches | Yes | Yes | Yes | Yes |
| Annual VIP gift | No | No | No | Yes |
| Birthday gems | Base amount | Higher | Higher again | Highest |
Tiers are reviewed once a year. Twelve months after a member reaches a tier, BOJ checks whether the required spend was met over the past year, and a member who fell short can be moved to a lower tier. Birthday gems rise with each tier, though BOJ doesn't publish the amounts above Amber.
The fine print
- One redeemed code per order. A code can't be combined with another redeemed code or used again.
- Gems start from sign-up. Past orders don't earn gems.
- Tiers can go down. Spend is reviewed 12 months after reaching a tier, and a member who didn't spend the tier's amount over that year may drop.
- Expiry isn't stated. BOJ's rewards page and FAQ don't say whether gems expire.
- Reviews are capped but unspecified. Reviews earn up to 150 gems, and BOJ doesn't publish how the amount is decided.
What stands out about BOJ Rewards
A cash conversion beside the product rewards. Most programs ask a member to pick a reward from a list. BOJ lets members convert 80 gems into $5, which makes the value of every other option easy to check.
Social and newsletter gems make the first 150 gems easy. Joining, subscribing and following on two networks pay 150 gems before a first purchase, which is a worthwhile $9.38. It brings a new customer onto the email list and the social accounts in the same step.
Tier upgrades pay a lump sum, not a faster earn rate. A Jade member moving to Pearl gets 200 gems, but earns the same 1 gem per $1. The reward for climbing is a one-off bonus, early access and, at the top, a gift, so the tiers add status without making the program cost more per order.
Full-size products as the top reward. A free Dynasty Cream 100ml for 1,000 gems gives members something concrete to save toward, and it sets the highest gem price on a product rather than a discount.
What members should know going in:
- Tier perks lean on early access and gifts. Members who want a faster earn rate at higher tiers won't find one published.
- No gem expiry is published, which is good for members now but leaves the rule open.
Is BOJ Rewards worth joining?
If you buy from Beauty of Joseon at all, yes: it is free, and joining, the newsletter and two follows put 150 gems in the account straight away. An occasional buyer who orders once or twice a year will mostly use the sign-up gems and the birthday gems, and converting 80 gems into $5 is a simple way to use them. A regular buyer earns about 6% back at the base rate, and the tier upgrade bonuses push that up a little as spend passes $300, $600 and $1,000. Someone who cares about early access to launches gets it from the first day as an Amber member. The Sapphire tier makes sense for heavy buyers who want the annual gift, though $1,000 of spend is a high bar for most shoppers.
What Shopify brands can learn from BOJ Rewards
BOJ Rewards is small and easy to read, and several of its choices carry over to a Shopify brand:
- Publish the exchange rate. "80 gems = $5" lets a customer work out what a point is worth in a second. Give your points a rate that is easy to calculate. Mage lets you set earning rates per $1 and fixed-amount rewards, and flexible rewards that let customers slide points against a value range.
- Pay for the actions that build your audience. BOJ pays for the newsletter and two social follows. In Mage, earning rules include account signup bonuses, social follows and shares with your profile URL, and newsletter sign-ups captured by a popup app can award points or store credit.
- Give a bonus when someone moves up a tier. A one-off upgrade gift marks the moment a customer reaches a new level without raising your earn rate. In Mage, VIP tiers can be set by amount spent, points earned or number of orders, and Points Drops can add a one-time bonus to members of a VIP tier.
- Scale the birthday reward with status. BOJ's birthday gems rise with tier. In Mage, birthday rewards can scale by tier, from bonus points up to free products, and tiers can carry early access to launches.
- Give both sides of a referral something. A friend gets 20% off and the referrer gets 150 gems. Mage's referrals pay the friend and the advocate different rewards, such as a percentage off, a fixed amount, points or store credit.
If you're building a points and tiers loyalty program on Shopify, Mage covers the structure above: points with fixed-amount, percentage and free-product rewards, VIP tiers on amount spent, points earned or number of orders, tier perks such as multipliers and early access, social and newsletter earning rules, Points Drops and referrals.
