- Navigate to the "Verify HUID" tool on the dashboard.
- Enter the 6-digit alphanumeric code stamped inside the ornament.

Check the individual HUID record and invoice details before completing a purchase.
Gold Purity Explained: 24K, 22K, 18K, and 14K
Carat (K) measures the purity of gold alloyed with secondary metals for strength and durability. Pure gold is 24 Carats but is too soft for daily jewellery wear.
- 24K (99.9% Pure): Primarily used for bullion bars, coins, and special ornaments; bright yellow tone.
- 22K (91.6% Pure): The traditional Indian standard for bridal necklaces, bangles, and kadas; warm deep yellow.
- 18K (75.0% Pure): Excellent durability; preferred for stone-studded necklaces, diamond rings, and rose/white gold styles.
- 14K (58.5% Pure): Highly durable alloy; excellent for modern light-weight rings and delicate everyday chains.
Strict Standards
Ask for an invoice that clearly describes the selected ornament and applicable details.
Natural vs Lab-Grown Diamonds: Factual Differences
Both natural diamonds and laboratory-grown diamonds share identical physical, chemical, and optical characteristics. Their primary differences relate to origin, scale of rarity, and long-term resale policies.
- Natural Diamonds: Formed within the Earth over geological time. For an individual stone or ornament, ask whether an independent grading report is supplied and verify that it matches the selected item.
- Lab-Grown Diamonds: Cultivated in modern laboratory reactors replicating geological heat and pressure; chemically identical but produced in controlled volumes.
Product Documentation
Ask whether the selected stone includes a grading report or inscription.
