Precious vs Semi-Precious Gemstones: What’s the Difference? (Indian Buyer’s Guide)
Gemstones have been celebrated in Indian jewellery for centuries—admired for their colour, brilliance, symbolism, and timeless appeal. Today, as more people move toward custom and bespoke jewellery, understanding gemstone categories helps you choose pieces that match your style, purpose, and budget.
At ASTU Jewellery, Mumbai, every gemstone—precious or semi-precious—is transformed into a handcrafted masterpiece. Our bespoke rings, bridal sets, and daily-wear jewels combine heritage craftsmanship with modern design. This guide simplifies the difference between precious and semi-precious gemstones, helping you select the perfect stone for your next custom piece.
What Are Precious Gemstones?
Traditionally, only four gemstones are classified as precious due to their rarity, exceptional value, and historical significance:
1. Diamond
Celebrated for unmatched brilliance and durability (10/10 on Mohs scale), diamonds remain the top choice for Indian engagement rings. ASTU features several stunning pieces with diamond artistry, such as the Yellow Sapphire and Diamond Solara Ring and the Blue Sapphire and Diamond Statement Ring, which beautifully highlight diamond’s sparkle.
2. Ruby
Ruby’s vibrant red symbolizes passion and strength, making it popular in bridal and heirloom jewellery. ASTU’s Ruby and Diamond Double-Band Flora Ring showcases ruby’s elegance with a contemporary twist.
3. Sapphire
Best known in royal blue, sapphires come in many colours and are extremely durable. Our collection includes the striking Multi-colour Sapphire 14K Gold Ring, ideal for those seeking a bold and expressive sapphire piece.
4. Emerald
Renowned for their lush green colour, emeralds are iconic in Indian jewellery. ASTU’s Emerald and Diamond Multi-Band Ring, Emerald and Diamond Cocktail Ring, and Dainty Emerald 14K Gold Ring are top choices for custom creations that blend tradition with a modern aesthetic.
Precious gemstones at ASTU frequently feature in luxury designs such as:
-
Emerald and diamond cocktail rings

What Are Semi-Precious Gemstones?
Semi-precious gemstones include a diverse range of stones admired for their unique colours, patterns, and affordability. These stones allow for more experimentation in bespoke designs.
Popular Semi-Precious Gemstones in India (Featured at ASTU)
Tanzanite – Seen in the Tanzanite 14k Gold Ring and Tanzanite & Emerald Estate Ring, this rare violet-blue gemstone brings contemporary elegance to engagement rings and cocktail pieces.
Tourmaline – The Pink Tourmaline Double-Band 14k Gold Ring is a perfect example of the gemstone’s romantic tones and versatility.
Amethyst – Adds rich purple tones to bespoke rings and daily-wear jewellery.
Opal – The Opal 14K Gold Ring highlights the gemstone’s signature rainbow-like iridescence.
Turquoise – Often used for vibrant, artistic custom designs.
Multi-colour Sapphires – While sapphire is technically precious, many varieties used in market practice fall under semi-precious categorization. The Multi-Colour Sapphire 14k Gold Ring showcases this beautifully.
Semi-precious gemstones at ASTU offer endless design freedom—perfect for custom rings, cocktail jewellery, and artistic statement pieces.
Key Differences Between Precious & Semi-Precious Gemstones
1. Rarity
Precious gemstones are significantly rarer, which increases their value and desirability. Semi-precious stones are more abundant and accessible.
2. Value
Precious stones—like diamonds, rubies, sapphires, and emeralds—retain higher market value over time. Semi-precious stones offer versatility and affordability, making them ideal for experimental or fashion-forward designs.
3. Durability
Diamonds, rubies, and sapphires are extremely durable, perfect for everyday wear such as engagement rings. Some semi-precious stones like opal, tanzanite, or turquoise may require extra care.
4. Aesthetic Variety
Semi-precious gemstones provide a richer palette of colours and artistic opportunities, enabling truly unique bespoke creations.
5. Usage in Indian Jewellery
Precious stones dominate bridal jewellery and heirloom collections, while semi-precious stones shine in contemporary, fusion, and daily-wear pieces.
