The Montare Standard
The diamond this setting
was built to hold.
Every stone we source must meet our non-negotiable specifications — verified by certificate and by eye. A diamond can pass grading and still fall short of how it performs under light. We check both.
Crafted For You
Made to order in 2–4 weeks.
Every Montare ring is set, polished, and inspected to your specification. Sizing, engraving, and finish are confirmed during your consultation before production begins. No inventory — just your ring, built for you.
Questions Answered
Before you order.
What is included in the price?◆
The setting, the centre diamond (lab-grown, IGI-certified), and all side stones. Interior engraving (up to 30 characters), prong refinement, hallmark positioning, and sizing are arranged during your consultation at no separate charge.
Can I customise the setting?◆
Yes — claw count, halo style, side-stone arrangement, basket depth, and prong profile can all be tuned during the consultation. We share renderings before production starts.
Are the diamonds lab-grown or natural?◆
All Montare stones are lab-grown — chemically and optically identical to mined diamonds, IGI-certified, and held to our VVS1–VVS2 clarity and D/E colour standard. Same brilliance, fraction of the impact.
What is the difference between 14k and 18k gold?◆
14k gold (58.3% pure) is harder and more scratch-resistant — ideal for daily wear. 18k gold (75% pure) has a richer colour and slightly higher lustre. Both are excellent for engagement rings.
Is Platinum worth it for a ring?◆
For everyday wear, platinum is the most durable option. It does not fade or require rhodium re-plating like white gold. It is heavier and more expensive due to material density — roughly 40% more metal by weight for the same setting.
How long does production take?◆
2–4 weeks from consultation confirmation. Your ring is crafted to order — not pulled from inventory. We confirm sizing, metal, and centre-stone selection before production begins.
What if I need to resize after delivery?◆
One complimentary resize is included within the first year. Additional resizes are available at cost. Some designs (eternity bands, channel set) cannot be resized due to stone coverage — we will advise during consultation.
