In Singapore, the gemstone engagement ring is redefining tradition. While diamonds remain a classic, modern couples are increasingly seeking the rarity, colour, and personal narrative that only a coloured gemstone can offer. At GIOIA Fine Jewellery, we move beyond the commercial standard to offer the truly exceptional—from unheated Sapphires to neon Paraiba Tourmalines.
Guide to Custom Gemstone Rings
Sapphire Engagement Rings: Beyond Royal Blue
As the most durable coloured gemstone (9 on the Mohs scale), Sapphires are the premier choice for daily wear. While the classic Royal Blue is timeless, GIOIA specialises in the rare and unheated varieties that mass-market jewellers cannot source.
- Padparadscha Sapphire: The rarest of all sapphires, featuring a delicate mix of pink and orange (the “lotus blossom” hue). We source unheated stones with the perfect 50/50 colour balance.
- Teal & Mermaid Sapphire: A sophisticated blend of blue and green, ideal for organic, nature-inspired ring designs.
- Unheated Royal Blue: Vivid, velvety saturation without the heat treatment common in commercial jewellery.

Ruby Engagement Rings: The Pigeon Blood Standard
The King of Gems, representing passion and vitality. At GIOIA, we look beyond the colour red. Our focus is on Unheated Rubies from Mozambique and Burma (Myanmar), specifically targeting the coveted “Pigeon Blood” rarity. Unlike treated stones, a GIOIA ruby is an investment-grade gem with natural fluorescence that glows in sunlight.

Paraiba Tourmaline Engagement Rings: The Neon Glow
For the couple who refuses to blend in. While diamonds rely on external light to sparkle, Paraiba Tourmaline is famous for its intrinsic “neon” glow. We source these rare gems directly from Brazil and Mozambique, looking for the unique presence of Copper and Manganese—the chemical combination that gives the stone its electric blue-green hue.

Emerald Engagement Rings: The Lush Garden
A symbol of rebirth and abundance. Emeralds require expertise to buy safely. We educate our clients on the importance of “Minor Oil” vs. “Moderate” treatments. Our collection features prime origins like Muzo Green (Colombia) and Zambia, selected for their glowing vitality and clarity.

Spinel Engagement Rings: The “Sparkle” Brilliance
Once a secret of gemologists, Spinel is the rising star of bespoke jewellery. Unlike Rubies (which are doubly refractive), Spinel is singly refractive—just like a diamond. We specialise in a wide spectrum of Spinel colours—from neon pink to metallic grey—stones with such high saturation that they appear self-luminous. Being 100% natural and typically untreated, they are the purest choice for a gemstone connoisseur.

Frequently Asked Questions
Find answers to commonly asked questions about our uniquely designed gemstone engagement rings.
Are coloured gemstones durable enough for daily wear?
Yes, but the choice of gemstone matters. We highly recommend Sapphires and Rubies (Mohs 9) or Spinels (Mohs 8) for engagement rings, as they are durable enough to withstand daily activities. We generally advise against softer stones like Opal or Pearl for rings that will be worn every day unless you are committed to extra care.
What is the difference between Heated and Unheated gemstones?
Unheated gemstones are completely natural and have not undergone thermal treatment to enhance their colour or clarity. They are significantly rarer and hold higher investment value. At GIOIA, we specialise in unheated Pigeon Blood Rubies and Royal Blue Sapphires, ensuring you own a gem of pure, natural beauty.
Do your gemstones come with certification?
Absolutely. Authenticity is our promise. Our rare gemstones are certified by renowned independent laboratories such as GRS, GIA or Local NGI. This certification verifies the gemstone’s origin (e.g., Burma, Sri Lanka, Colombia) and confirms whether it is natural and unheated.
How long does the bespoke design process take?
The entire journey, from the initial consultation and gemstone selection to the final handcrafted ring, typically takes 12 to 14 weeks. If you have a specific proposal date, please let us know during the consultation, and we will do our best to accommodate your timeline.
Are your gemstones ethically sourced?
Yes. We take great pride in our responsible sourcing. By buying directly from miners and trusted suppliers in origins like Sri Lanka, Mozambique, and Colombia, we ensure our gemstones are conflict-free and ethically obtained. This direct sourcing not only guarantees the integrity of the gem but also allows us to offer you the finest quality at competitive value.
Are gemstone engagement rings a good investment compared to diamonds?
While commercial diamonds often depreciate after purchase, rare, high-quality coloured gemstones—specifically Unheated Sapphires, Pigeon Blood Rubies, and Paraiba Tourmalines—have a history of retaining or increasing in value due to their extreme scarcity.
Unlike diamonds, which are available in large quantities, a fine quality coloured gemstone is a unique asset, making it a true heirloom piece to pass down to future generations.
