2. What Is ONYA Diamonds?
ONYA Diamonds is a Bengaluru-based lab-grown diamond jewellery brand founded in 2024 by Himani Yadav and Gaurav Choudhary. The brand positions itself at the intersection of conscious luxury and accessible elegance, offering IGI-certified lab-grown diamond jewellery across rings, pendants, earrings, necklaces, bracelets, and mangalsutras. ONYA's core promise is "intelligent luxury" — high-quality diamond jewellery (VVS-EF grade) without the mined-diamond price tag, backed by lifetime exchange (100%) and buyback (80%) policies.
The brand operates an omnichannel model combining a Shopify-powered D2C e-commerce platform with physical retail stores across Bengaluru. Within roughly a year of founding, ONYA expanded to six company-owned stores in Bangalore neighborhoods (Jayanagar, HSR Layout, Sarjapur, Indiranagar, Whitefield Main Road, and Neeladri Road), with a franchise program for wider expansion. The brand targets India's growing segment of young, educated, sustainability-conscious consumers — particularly tech-sector professionals in urban centers — who want premium diamond jewellery at transparent prices.
ONYA differentiates through its buyback/exchange policy, bespoke customization service, transparent order tracking (CAD to delivery), and a content-driven approach that benchmarks competitors publicly.

| Baseline | Aug–Sep 2025 | 94.0% | 6.0% | 15.5:1 |
| Mobile Peak | Oct–Nov 2025 | 94.8% | 5.2% | 18.1:1 |

Key Findings
- **Overwhelmingly mobile**: 92.3% phone share in the latest period — one of the highest mobile ratios for any Indian e-commerce site, indicating a young, mobile-native audience.
- **Desktop doubled over 10 months**: Desktop share rose from ~5% (Oct-Nov 2025) to ~8% (Spring 2026), a 3.2 pp increase. This suggests growing high-value purchase behavior (desktop users tend to convert at higher AOV for jewellery).
- **Holiday desktop spike**: December 2025–January 2026 saw desktop peak at 11.2% (Feb 8–Mar 7), likely driven by wedding/engagement season research and purchase behavior.
- **Tablet is zero**: 0.00% across all 40 data points — tablet is irrelevant for this audience.
- **Implication**: Mobile-first UX is critical. The site must load fast on mobile, have thumb-friendly CTAs, and offer a seamless mobile checkout. The rising desktop share suggests a growing segment of high-intent buyers who prefer larger screens for high-value purchases.

| **No subscription/EMI prominent** | No visible EMI or subscription financing option on product pages — could increase conversion for ₹50K+ items | Low | High | Yes |
| **No marketplace presence** | Absent from Amazon, Flipkart, Myntra — missing discovery-driven shoppers | Medium | Medium | Yes |
| **Limited international** | No international shipping or global presence despite lab-grown diamonds being a global market | High | Medium | Long-term |
