Every Monday drop at SARDA™ begins with the stones — and this week's lineup is one worth studying. From the warm golden shimmer of a hand-carved Labradorite from Madagascar to the minty luminosity of irradiated Prasiolite from Brazil, the June 29 debut brings two distinct collections and four remarkable gem types into the SARDA family. Here's the full breakdown.

Golden Sheen Labradorite — One That I Can Call Collection

At first glance, Golden Sheen Labradorite looks like a richly polished oval with deep, warm depth. Then the light shifts — and a luminous golden shimmer radiates from within. This is adularescence, the optical phenomenon that makes labradorite unlike almost any other stone. While classic labradorite typically shows a blue or teal flash, the golden sheen variety reveals a warm, honeyed interior glow that moves beautifully with the wearer.

This week's pieces feature stones sourced from Madagascar, one of the world's premier sources for gem-quality labradorite. The stones are entirely untreated — no heat, no coating, nothing added — pure natural beauty. What makes these pieces especially singular is the cut: an oval carved cabochon featuring a dragonfly design, each stone weighing approximately 22.53 carats. The artisan stone carvers have worked the dragonfly motif directly into the surface of the cabochon — meaning the symbol lives in the stone itself, not the setting.

Labradorite was first documented by European explorers in the 1770s on the Labrador Peninsula in Canada. Inuit peoples have long treasured this stone, believing it captured the lights of the aurora borealis within its surface. The golden sheen variety is especially prized for the rarity of its warm-toned flash. Learn more at GIA.

Mohs Hardness: 6–6.5. Store separately from harder stones and avoid rough surfaces. Clean gently with a soft, damp cloth.

Golden Sheen Labradorite debuts this week in the One That I Can Call collection as a bracelet, ring, and pendant.

Prasiolite — Glory To U Alone Collection

Soft, minty, and quietly luminous — Prasiolite is one of those stones that rewards a long look. This transparent, pale-to-medium green variety of quartz has a cool, fresh quality that takes a faceted cut beautifully. This week's pieces feature Prasiolite in a generous cushion square cut at 4.13 carats, held in a birdnest-style setting that gives the stone room to glow.

Prasiolite originates from Brazil, the world's primary source. The stone is irradiated — a controlled process that converts amethyst's purple tones into Prasiolite's characteristic green. Natural untreated Prasiolite is exceedingly rare; virtually all commercial Prasiolite undergoes irradiation. The name comes from the Greek "prason" (leek) and "lithos" (stone) — a reference to its cool, vegetable green. Read more at the International Gem Society.

Mohs Hardness: 7. Relatively durable for daily wear. Avoid prolonged heat or intense direct sunlight, as high temperatures can gradually affect the color of irradiated stones over time. Clean with mild soap and lukewarm water; rinse thoroughly.

Prasiolite debuts in the Glory To U Alone collection as a bracelet, ring, and pendant, always in combination with Peridot and Bali Crush™ Mystic Topaz.

Peridot — Glory To U Alone Collection

Few gemstones have a history as long as Peridot. One of the rare gems that exists in only one color family — a vivid, iron-rich green ranging from yellow-green to olive — Peridot was mined in ancient Egypt as early as 1500 BCE on the island of Zabargad. Ancient Egyptians called it the "gem of the sun" and prized it highly. It remains the August birthstone and one of history's most continuously beloved gems.

This week's Peridot is sourced from China, a major producer of fine gem-quality material, and is completely natural with no treatment. The stones appear in pear and round cuts (0.20–0.65 carats each) as elegant accent companions to the larger Prasiolite and the rainbow-flash Bali Crush™ Mystic Topaz. The interplay of Peridot's clean olive green with Prasiolite's minty softness is one of this week's most distinctive pairings. Learn more at GIA.

Mohs Hardness: 6.5–7. Peridot can be slightly brittle — avoid hard impacts and sudden temperature changes. Warm soapy water is ideal; skip ultrasonic and steam cleaners.

Peridot appears throughout the Glory To U Alone bracelet, rings, and pendant.

Bali Crush™ Mystic Topaz — Glory To U Alone Collection

Bali Crush™ Mystic Topaz is SARDA's signature name for their square princess cut mystic topaz accent stones — and once you see them in motion, the sparkle is hard to look away from. Mystic Topaz starts as a natural white topaz from Brazil and is treated using PVD (Physical Vapor Deposition), an ultra-thin metallic coating applied at the molecular level that creates a spectacular rainbow effect. Depending on the viewing angle, you'll see simultaneous flashes of blue, green, gold, pink, and purple.

At 1.15 carats in a crisp square princess cut, these accent stones bring bold spectral sparkle to the Glory To U Alone pieces without overpowering the softer tones of Prasiolite and Peridot. The Bali Crush™ stones are the element that binds the entire multi-stone palette together — earthy meets electric. For more on topaz, see GIA's Topaz overview.

Mohs Hardness: 8 (topaz base). Hard and durable, but the PVD coating needs gentle handling — avoid abrasive cleaners, ultrasonic baths, and contact with harder stones. Clean with a soft cloth and mild soapy water.

Bali Crush™ Mystic Topaz features in the Glory To U Alone bracelet and rings.

Caring for This Week's Stones

Four stone types, four slightly different care profiles — here's a quick reference:

• Golden Sheen Labradorite (Mohs 6–6.5): Store separately from harder stones. Clean with a soft damp cloth; avoid abrasive contact near the carved cabochon surface.
• Prasiolite (Mohs 7): Avoid sustained heat or strong direct sunlight. Mild soap and lukewarm water; rinse well and pat dry.
• Peridot (Mohs 6.5–7): Skip the ultrasonic cleaner. Warm soapy water only; avoid sudden temperature changes and hard impacts.
• Bali Crush™ Mystic Topaz (Mohs 8 base): The PVD coating needs gentle care — no ultrasonic, no abrasives. A soft cloth and mild soap keep it looking brilliant.
