Things to Be Mindful Of

  • IGI certification for every stone is non-negotiable — it is the only real trust signal
  • In-home try-on (courier certified stones with a ₹5,000 refundable deposit) dramatically improves D2C conversion

Unit Economics

Real benchmarks from Indian operators in this space

Customer Acq. Cost

i
How much you spend to win one paying customer — ads, commissions, referrals. Lower is better. Aim to recover this within 3–6 months.

₹1,500–5,000

Lifetime Value

i
Total revenue you expect from one customer over their entire relationship with you. Higher LTV = more room to spend on acquisition.

₹25,000–80,000

LTV : CAC

i
Ratio of lifetime value to acquisition cost. A ratio above 3:1 is healthy; above 5:1 is excellent. Below 1:1 means you're losing money on each customer.

12:1

Avg Order Value

i
Average amount a customer spends per transaction. Increasing this (via upsells or bundles) is one of the fastest ways to grow revenue without new customers.

₹18,000

Monthly Churn

i
Percentage of customers who stop paying each month. 2–5% is typical for Indian B2C; under 1% for B2B SaaS. High churn kills growth even with strong acquisition.

Low — occasion-based repurchase

CAC Payback

i
How long until a customer's payments cover what you spent to acquire them. Under 12 months is strong. Shorter payback = faster you can reinvest in growth.

2–4 months

High-ticket purchase; Instagram + Google conversion funnel takes 3–5 touchpoints before purchase.

What Worked

Surat is the world's largest diamond cutting hub — lab diamonds at 70% lower price than mined. Targeted urban brides who wanted size over brand. Average order value ₹22,000 vs ₹80,000 for mined.

Biggest Mistake

Tried to sell online without certification. International Gemological Institute (IGI) certification for each stone added ₹800/unit cost but converted skeptics — 40% lower return rate.

Pros & Cons

Pros

  • India is the world leader in lab-grown diamond manufacturing (Surat)
  • 70-80% cost advantage over mined diamonds
  • Millennial bridal market shifting to lab-grown globally

Cons

  • Consumer education on LGD is needed — perception issues
  • IGI/GIA certification adds ₹5,000-15,000 per stone
  • HUID hallmarking compliance is complex for gold-set LGD jewellery
