Live diamond feed · Corona, CA origin
Every certified diamond and custom ring, on one live feed.
Caratstrand is the asset-light diamond network spun out of a California family jeweler. We connect independent retailers, kiosk-scale operators, and engagement-ring shoppers directly to wholesale supply — natural and lab-grown stones, GIA and IGI grading, HD assets, and a configurable custom manufacturing pipeline, all under a single real-time inventory layer.

The feed · a single inventory layer
One stream. Five things to know about what's on it.
Caratstrand pulls every certified stone, finished piece, and configured order onto the same publish-ready surface. Operators pick what shows; the shopper sees what's verifiable. Nobody carries inventory that isn't held upstream.
A live, scrollable feed of certified inventory
Each row of the feed is a real-time holdable SKU. Stock counts flow from upstream wholesalers in seconds; you can publish this same feed under your store label without owning a single diamond.

Honest lab-grown transparency
Operators can toggle lab-grown on or off per channel — but the choice is labeled, never substituted. IGI reports screen-side-by-side with GIA, so a shopper sees exactly which is which.
GIA + IGI reports, attached to the stone
Every row links to the original grading packet. No PDFs mailed later, no "request a copy" gates — verification is part of the browsing experience, not a sales follow-up.
Studio photography and 360° by default
HD photo and video assets follow each stone into your storefront. The same asset pack ships to the customer with the order — so what they bought online is what arrives, presented identically.
Custom manufacturing on the same wire
Engagements, weddings, and personalized pieces route to a partner bench through the same certified pipeline. Operators track every milestone; shoppers see the same real-time status as the retailer.
For retailers · kiosk-scale operators
Small-footprint stores compete with national chains — without the inventory.
A two-bench jeweler in a Southern California strip mall used to need a million-dollar stone case. Caratstrand replaces the case with a feed that mirrors the largest wholesalers in the country, plus a manufacturing pipeline for the engagement rings those wholesalers don't carry.

- Drop-shipping insured to your customer, hand-tied with the original grading packet
- Operator dashboard shows holds, conversions, and feed health at a glance
- Carrier-grade delivery in 2-5 business days, branded to your store

For shoppers · the engagement ring question
One-of-a-kind settings, backed by a verifiable Supply chain.
Most jewelers hand you a setting book and call it customization. We hand you the same certified supply chain that powers the inventory feed — every center stone is held upstream, every report is attached, every milestone is visible to you and to your partner retailer.
- Configurable across metal, profile, side stones, and engraving
- Same GIA / IGI feed that the retailer sees — no two versions of the truth
- Order routed to a vetted bench; milestones surface to both sides of the sale
Trust · how a stone gets onto the feed
From the wholesale network to the customer, the chain stays visible.
Every stone traces the same four stages. We don't ship anything we can't hold upstream, and we don't publish anything we can't grade.
- 01
Wholesale source
Stone comes from an integrated wholesale network. The supplier holds it; we hold the data.
- 02
Graded · GIA or IGI
Natural stones resolve to a GIA report; lab-grown stones resolve to an IGI report. Both attached.
- 03
Captured · HD + 360°
Studio photography and 360° video are matched to that lot. The same asset ships with the order.
- 04
Held or drop-shipped
A hold is placed upstream at purchase. The stone ships insured, with the report, hand-tied.
