A yellow, lustrous metal that gathers instant attention when you adorn even a tiny piece. Gold has been used as a precious metal in various forms for centuries, owing to its radiance and socio-economic significance.
Colours of Gold
With innovation in jewellery design, jewellers experiment with designs and even colours of gold. The purest form is yellow, but when mixed with other metals, different colours become possible — yellow, rose, and white.
Rose gold is made by alloying gold with copper. The higher the copper content, the redder the gold. White gold is created when pure gold is alloyed with metals such as palladium, silver, or rhodium — a popular choice for wedding bands.
Gold Purity (Karat)
Gold purity is measured in karats (K). 24K is pure gold (99.9%), but it's too soft for everyday jewellery. Common purities include:
• 22K (91.6% pure) — ideal for traditional Indian jewellery
• 18K (75% pure) — perfect for diamond-studded pieces
• 14K (58.3% pure) — durable for everyday wear
At Heart of Gold, we use only BIS Hallmarked gold, ensuring certified purity in every creation.
How to Care for Gold Jewellery
1. Remove ornaments before bathing or applying perfumes and deodorants.
2. Avoid harsh chemical-based cleansing agents — they can corrode the metal.
3. Clean with warm water and a soft cloth.
4. Store pieces separately in soft pouches to maintain lustre.
5. Have your jewellery professionally cleaned once a year.
