White gold studs that sparkle

Upgraded my natural diamond ring
I sold my 1-carat natural diamond ring and upgraded to a 3-carat lab diamond from Alya Stone, and even had money extra, best decision ever. The new stone is identical in brilliance with better qaulity, and I love that it’s conflict-free. The pave setting is so well-made, and the white gold has a gorgeous luster. If you’re on the fence about lab diamonds, Alya Stone will change your mind!

⟡ Effortless quality– Default E color VS+ lab diamonds (bright & eye-clean)
Are lab-grown diamonds real diamonds?
Absolutely! Lab-created diamonds are 100% real diamonds - chemically, physically, and optically identical to mined diamonds. Both are composed of pure carbon crystallized in the cubic crystal structure, sharing the same:
- Hardness (10/10 on Mohs scale)
- Brilliance (refractive index of 2.42)
- Thermal conductivity
The only difference is origin: ours are grown in controlled environments using Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT) methods, avoiding the environmental and ethical concerns of mining.
Certification proves authenticity: Every Alya Stone diamond comes with an IGI or GIA certificate using the same strict 4Cs grading system (Cut, Color, Clarity, Carat) as mined diamonds.
Do lab diamonds hold their value like mined diamonds?
While both lab-grown and mined diamonds depreciate after purchase, lab diamonds typically resell for 20-40% of their original price compared to 30-50% for mined stones. But here's what really matters: since you're paying 60-80% less upfront for a lab diamond, your actual dollar loss is far smaller. For example, that means losing $2,800 on a $4,000 lab diamond versus $10,800 on an $18,000 mined diamond of the same quality. Remember, diamonds are about celebrating love, not storing wealth.
Are lab diamonds good for daily wear?
Lab diamonds are equally durable as mined diamonds:
- Hardness: 10/10 (scratch-resistant)
- Best for: Engagement rings, eternity bands, right-hand rings
- Care Tips:
How do I verify my diamond’s quality?
We provide triple verification:
- IGI Certificate: Details exact 4Cs grades
- Laser Inscription: Micro-engraved ID matching the certificate
- HD Video (upon request): Inspect fire and scintillation before buying
Red Flags to Avoid:
- No certification
- Cloudy "fuzzy" diamonds (potential undisclosed treatments)
- Overly cheap prices (may be cubic zirconia or moissanite)
Every love story deserves a symbol as extraordinary as its promise. Our exquisite lab-grown diamond engagement rings blend timeless elegance with cutting-edge innovation, offering ethically crafted, IGI-certified diamonds that rival mined stones in brilliance, clarity, and durability—at 50-80% less cost.
