METALS
Gold Weight
All UNCUT jewelry pieces are handcrafted, which may result in slight variations in the final gold weight compared to the initial estimate. These variations occur due to artisanal processes such as hand-setting of stones, filing, polishing, and finishing. The final invoice reflects the actual gold weight of the finished piece.
Kundan Gold - 22K
UNCUT Jewelry uses Kundan gold in traditional Kundan settings, where gold is hand-worked to encase gemstones. As Kundan gold is naturally soft, slight variations in finish are inherent to the artisanal process and a hallmark of its authenticity. Each piece is crafted to meet our exacting standards of beauty and durability.
18K Gold
UNCUT Jewelry uses 18K hallmarked gold (75% purity), offering the ideal blend of strength, durability, and a rich, luxurious hue. Each piece bears the official BIS government hallmark, certifying gold purity and authenticity to the highest standards.
Silver 900 (90% Purity)
UNCUT Jewelry uses Silver 900 (90% purity), a durable and lustrous alloy valued for its rich tone and strength. Ideal for select handcrafted designs, it offers distinctive character while meeting our high standards of quality and craftsmanship.
DIAMONDS
Uncut Diamonds / Polki Diamonds / Vilandi
Polki refers to natural, uncut diamonds that are hand-polished without modern faceting. Being natural stones, each Polki diamond may have slight variations in shape, size, and lustre, as well as natural inclusions. These are not flaws, but inherent characteristics—a mark of their authenticity and charm.
At UNCUT Jewelry, we work exclusively with Syndicate Polki—the highest quality grade, valued for its superior lustre, minimal visible inclusions, and exceptional durability. This ensures that every piece we create is not only beautiful, but also heirloom-worthy.
Natural Diamonds
All diamonds used in UNCUT Jewelry are natural, sourced responsibly, and certified FG VVS quality unless otherwise specified. Minor inclusions, visible only under magnification, are part of the diamond’s natural formation and do not compromise its beauty, brilliance, or value.
STONES
Rubies
UNCUT Jewelry uses only natural, heat-treated rubies, a standard and widely accepted enhancement in fine jewelry. Heat treatment improves a ruby’s color and clarity without compromising its durability or authenticity. We do not use glass-filled or fracture-filled rubies, ensuring every gemstone meets our heirloom-quality standards.
Glass-Filled Ruby
Glass-filled rubies are natural corundum stones treated with lead glass to improve their appearance. These stones require extra care and should be protected from harsh chemicals, ultrasonic cleaning, and extreme heat.
Lab-created rubies
These earrings use lab-created rubies, which are chemically, physically, and optically identical to natural rubies. They offer the same brilliance and durability while being an ethical and sustainable alternative. Their vivid color and clarity mirror natural rubies, and slight variations in hue or inclusions may be visible, reflecting their unique growth process.

Care should be taken to avoid exposure to strong heat, harsh chemicals, or ultrasonic cleaning, as these may compromise the treatment.
Lab-Created Emerald
Lab-created emeralds are crafted to mirror the chemical composition, structure, and vibrant green beauty of natural emeralds. Slight internal characteristics may be present, just as in natural emeralds, and should be appreciated as part of the stone’s unique character. These gemstones offer elegance and durability at a more accessible value.
