New to buying sapphires? Start with our Ultimate Sapphire Buying Guide — the complete resource for color, origin, treatment, and pricing.

Buy Now, Pay Later for Loose Sapphires:

Fine loose sapphires are not impulse purchases. A 1.5-carat unheated Ceylon blue, a vivid teal sapphire for a custom engagement ring, a GIA-certified padparadscha — these are considered, deliberate acquisitions that buyers think about for weeks or months before committing. The stone is right. The price is fair. The only friction is timing: the budget is not quite there yet, or it is there but concentrating it into a single payment feels significant.

Shop Pay Installments solves that problem. Crescent Gems now offers Buy Now Pay Later at checkout through Shop Pay, powered by Affirm — giving you the ability to split your purchase into manageable payments while we ship your stone as soon as the order is placed. You get the stone now. You pay over time. The custom ring commission you have been planning does not have to wait another three months while you save.

How It Works

Shop Pay Installments appears automatically at checkout for eligible orders. You do not need to apply in advance, open a separate account, or contact us to activate it. When you reach the payment step at checkout, if your order qualifies, you will see the installment options alongside the standard payment methods. Select the plan that suits you, complete a brief eligibility check through Affirm, and your order ships on our standard timeline.

We receive full payment immediately from Affirm. You pay Affirm on your chosen schedule. The stone is yours from the moment the order is confirmed.

Payment Options

The options available to you depend on your order total. All amounts include any applicable shipping and taxes.

Interest-Free Bi-Weekly Payments

For orders between $50 and $999.99, you can split the total into four equal bi-weekly payments with zero interest and zero fees. A $800 teal sapphire becomes four payments of $200, two weeks apart. A $600 pink sapphire becomes four payments of $150. No interest, no catch — Affirm earns nothing on these transactions. The full purchase price is simply spread across eight weeks.

Monthly Installments

For orders between $150 and $30,000, monthly payment plans are available over 3, 6, 12, 18, or 24 months depending on the purchase amount. Interest rates range from 0% to 36% APR depending on your credit profile and the term selected — and the full rate is disclosed at checkout before you confirm, with no hidden fees or charges. A $2,400 unheated Ceylon blue at 12 monthly payments is $200 per month. A $4,800 GIA-documented padparadscha at 24 months is $200 per month. The stone you have been researching for three months does not need to wait another three.

Which Stones Does This Cover?

Shop Pay Installments applies to all products in our catalog within the eligible price range — from a $150 small unheated violet sapphire through our most significant GIA-documented stones. Every loose sapphire, garnet, ruby, chrysoberyl, and other gem we carry is eligible, with no exceptions within the $35–$30,000 order range.

This is particularly relevant for the purchase categories where timing most commonly creates friction:

  • Engagement ring center stones: The 1.0–1.5 carat range of unheated Ceylon sapphires most commonly sought for engagement rings — typically $1,500–$4,000 — is exactly where monthly installments make fine natural stone accessible without compromising on quality.
  • Jyotish gemstones: Planetary gemstones prescribed for Saturn, Jupiter, Venus, and other Navaratna applications often require unheated certified material at meaningful carat weights — $800–$3,000 is a common range. Spreading that over six months while wearing the stone immediately is a practical option many buyers will find useful.
  • Collector and investment stones: GIA-documented premium stones — unheated blue above 2 carats, fine padparadscha, collector-grade tsavorite — where the price reflects genuine rarity and the buyer's intent is long-term ownership. Monthly installments allow these acquisitions to happen at the right time rather than the available time.

Customer Eligibility

Shop Pay Installments is available to customers with a billing address in the United States. You need a Shop Pay account (free, created at checkout if you do not already have one) and a supported debit or credit card. Eligibility for specific payment plans is determined by Affirm at checkout based on a soft credit check that does not affect your credit score. Not every customer will qualify for every plan — final approval is at Affirm's discretion — but the eligibility check takes seconds and the outcome is disclosed before you commit to anything.

A few practical notes: Capital One and Chase credit cards are not accepted for monthly payment plans (they are accepted for bi-weekly interest-free plans). Prepaid cards are not accepted. Monthly payment plans require a debit card.

What This Does Not Change

Our 14-day return policy applies to all orders regardless of payment method, including Shop Pay Installments purchases. If you receive a stone and it is not right — color different from what the photographs conveyed, clarity not as described — you can return it within 14 days for a full refund, and Affirm adjusts the installment plan accordingly.

Our disclosure standards do not change either. Every stone in our catalog has treatment status stated on the product page, GIA documentation noted where applicable, and our direct Ceylon sourcing as the foundation of every purchase. Financing makes the payment more flexible; it does not change what you are buying or how we represent it.

A Note on the Try-before you buy Program

Several stones in our catalog are available through the Try-before you Buy program — we ship the loose stone for home evaluation before you commit. The Try-before you buy and Shop Pay Installments DO NOT WORK TOGETHER , In these instances you can Buy the stone using our installment plan and return it with in 14 days if it does not work.

How to Use It

  1. Browse the full catalog or any color collection and add your chosen stone to the cart.
  2. Proceed to checkout as normal.
  3. At the payment step, select Shop Pay.
  4. If your order qualifies, the installment options appear — choose the plan that suits your timeline.
  5. Complete the brief Affirm eligibility check (seconds, no credit score impact).
  6. Confirm your order. We ship on our standard timeline.
