Gold, Diamonds, Care & Certification
This is DEEVE's complete jewelry education library — science-based guides covering gold purity (14K vs 18K), lab-grown diamonds, IGI and GIA certification, the 4Cs, jewelry care, sizing, and styling. Every guide is authored by Ara Talachian, Master Goldsmith & Certified Gemologist, and grounded in materials science and gemology — not marketing copy.
Quick Answer: 6 Key Facts About Fine Jewelry
- 14K gold is the durability standard — 58.3% pure gold, harder than 18K, ideal for everyday fine jewelry
- Lab-grown diamonds are real diamonds — chemically identical to natural, IGI/GIA certified, 50–80% lower price
- IGI is the #1 certification for lab-grown diamonds — full 4Cs grading; GIA is the standard for natural diamonds
- Cut is the most important of the 4Cs — Excellent/Ideal cut determines brilliance more than color or clarity
- VS2 clarity or better is eye-clean — inclusions invisible to the naked eye; best value for most buyers
- Solid gold requires minimal care — warm water + mild soap monthly; store separately to avoid scratching
Jewelry Guides & Education Hub
Expert, science-based guides to help you make informed decisions about fine jewelry. Written by Ara Talachian, Master Goldsmith & Certified Gemologist, Ontario, Canada.
Why Jewelry Education Matters
Purchasing fine jewelry is a significant investment — both financially and emotionally. Our education hubs are written by Ara Talachian and grounded in materials science and gemology — not marketing copy. Whether you're buying your first solid gold piece, selecting an engagement ring, or caring for inherited jewelry, the guides below give you the knowledge to make confident, lasting decisions.

Gold Education Hub
Gold is the foundation of fine jewelry — but not all gold is equal. Karat weight, alloy composition, and manufacturing method determine how a piece performs over years of daily wear. 14K gold (58.3% pure) is the industry standard for durability; 18K (75% pure) offers a richer tone but is softer.
Our gold guides are grounded in materials science — covering Vickers hardness data, alloy oxidation chemistry, and long-term wear analysis.

- Why gold plated jewelry fails
Diamond Education Hub
Lab-grown and natural diamonds are chemically, physically, and optically identical — both pure carbon in a cubic crystal lattice, both scoring 10 on the Mohs scale. The only difference is origin. Lab-grown diamonds are certified by IGI or GIA using identical grading standards.
Our diamond guides cover the full spectrum: the 4Cs, certification standards, growth methods, ethical sourcing, and realistic resale expectations.

- Diamond ethics and traceability
Jewelry Care Hub
Solid gold and diamond jewelry requires minimal maintenance compared to plated or fashion jewelry — but the right care practices make the difference between a piece that stays brilliant for decades and one that dulls prematurely.
Our care guides cover every material in DEEVE's collection: 14K and 18K gold, lab-grown diamonds, pearls, emeralds, sapphires, rubies, and turquoise.

Diamond Certificates Guide
A diamond certificate is the independent verification of a diamond's quality. It documents cut, color, clarity, and carat weight as assessed by a third-party gemological laboratory. Not all certificates are equal: IGI, GIA, and HRD use different grading scales.
Our certificate guides cover IGI, GIA, and HRD in detail — including how to verify authenticity and what each field on the report means.
